Year in review 2020. Let’s all agree to not look back. 20 papers for 2020<\/strong><\/p>\n

\"sarcastic

Unofficially the Official Logo of 2020…<\/p><\/div>\n

As the year comes to the close, we thought it was time to have a little fun and look back at the year in photochemistry. 2020 was a big year for us at HepatoChem under some trying circumstances. Before we move forward to 2021 with the launch of some exciting new equipment and products, we thought that we would look back at some of our favorite photochemistry work in the literature from the past year. A quick search finds a few thousand (photoredox, photocatalysis, photochemistry, metallaphotoredox) papers so far in 2020 and with(out lifting a finger to verify) very little research effort we’re willing to bet that this is more than in 2019. Many of the papers on the list break ground and move the field farther into unimaginable areas, while others find photochemical replacements for traditional reactions solving some unmet need. A few papers are outside the realm of topics that most of us spend any time thinking about but demonstrate the power of photochemistry. Some of the papers also include nice pictures of EvoluChem photoreactors and equipment and deserve a shout out. And a few others are just plain weird. And let’s face it, 2020 was weird for all of us.<\/p>\n

If you think we’ve missed your favorite paper or just want to send along an example of your work that you want us to recognize or recognize in the future, send us an email or respond to the tweet for this article (#photoredox20for2020<\/strong><\/a>) If you disagree with the list, let us know how we screwed up by sending us an email here<\/span>.<\/p>\n

To get started, a few FAQ about how we generated this list.<\/p>\n

What are the criteria for inclusion?<\/strong><\/p>\n

Each paper probably uses light in some way, either a bulb, LED, laser or sunlight. We started this exercise without any particular standards or criteria, other than the goal to share the papers we enjoyed (the most) and to make it fun. It then became readily apparent that there were far more than 20 papers worthy to be included, because there was a ridiculous amount of good work put out this year. So, at a certain point we just stopped adding more. Some of the work will likely be familiar to anyone used to the photochemical field; however, in our fake scoring system bonus points were given for open access papers and work from new professors.<\/p>\n

Why 20 papers?<\/strong><\/p>\n

The year is 2020, I can’t believe you asked this question.<\/p>\n

Are there 20 papers listed?<\/strong><\/p>\n

No, there are probably more or maybe less. You’ll need to read and count the entire list to find out.<\/p>\n

Is there a vote for best photochemistry achievement of 2020?<\/strong><\/p>\n

No. Awards are stupid. Do you really think we want to deal with running an internet voting poll and awarding photoredox achievement of the year to this? https:\/\/www.youtube.com\/watch?v=vfLZOkn0chc<\/strong><\/a><\/p>\n

Do the links for each article work?<\/strong><\/p>\n

Sometimes, when formatting an email or a links on website, links go to the wrong place. You can either be confused by this, email us and complain. Or use google and find the correct article. Your choice. Other times, links go to wrong place intentionally and you might find something fun.<\/p>\n

Do I win a prize if I click on each article?<\/strong><\/p>\n

You’ll have to click on each article to find out.<\/p>\n

How do I get my work on the 21 for 2021 list?<\/strong><\/p>\n

Go here and get to work<\/a>. Send us the paper once you’ve submitted.<\/p>\n

In no particular order, here are our 20 favorite photochemistry papers for 2020.<\/strong><\/p>\n

1: Organocatalyzed Birch Reduction Driven by Visible Light<\/strong><\/em><\/h3>\n

Our Take: <\/strong>We wrote about this one back here<\/span><\/a>. Just an incredible achievement to find this much reduction potential in a photocatalytic reaction with mild conditions. Unless you prefer running reactions with liquid ammonia.<\/p>\n

4: Photons as a 21st century reagent<\/strong><\/em><\/h3>\n

8: U.S. Food and Drug Administration-Certified Food Dyes as Organocatalysts in the Visible Light-Promoted Chlorination of Aromatics and Heteroaromatics<\/strong><\/em><\/h3>\n

Our Take:<\/strong> While it was the weirdness of the title that caught our eye here, being able to use non-toxic catalysts that are produced cheaply in metric ton quantities to do important chemistry is certainly valuable. There is only so much iridium out there for everyone else to use.<\/p>\n

Year in review 2020.\u00a0 Let\u2019s all agree to not look back.\u00a0 20 papers for 2020<\/strong><\/p>[caption id=\"attachment_8813\" align=\"alignright\" width=\"300\"]\"sarcastic Unofficially the Official Logo of 2020...[\/caption]

As the year comes to the close, we thought it was time to have a little fun and look back at the year in photochemistry.\u00a0 2020 was a big year for us at HepatoChem under some trying circumstances.\u00a0 Before we move forward to 2021 with the launch of some exciting new equipment and products, we thought that we would look back at some of our favorite photochemistry work in the literature from the past year.\u00a0 A quick search finds a few thousand (photoredox, photocatalysis, photochemistry, metallaphotoredox) papers so far in 2020 and with(out lifting a finger to verify) very little research effort we\u2019re willing to bet that this is more than in 2019.\u00a0 \u00a0Many of the papers on the list break ground and move the field farther into unimaginable areas, while others find photochemical replacements for traditional reactions solving some unmet need. \u00a0\u00a0A few papers are outside the realm of topics that most of us spend any time thinking about but demonstrate the power of photochemistry. \u00a0Some of the papers also include nice pictures of EvoluChem photoreactors and equipment and deserve a shout out.\u00a0 And a few others are just plain weird.\u00a0 And let\u2019s face it, 2020 was weird for all of us.<\/p>

If you think we\u2019ve missed your favorite paper or just want to send along an example of your work that you want us to recognize or recognize in the future, send us an email or respond to the tweet for this article (#photoredox20for2020<\/strong><\/a>)\u00a0 If you disagree with the list, let us know how we screwed up by sending us an email here<\/span>.<\/p>

To get started, a few FAQ about how we generated this list.<\/p>

What are the criteria for inclusion?<\/strong><\/p>

Each paper probably uses light in some way, either a bulb, LED, laser or sunlight.\u00a0 We started this exercise without any particular standards or criteria, other than the goal to share the papers we enjoyed (the most) and to make it fun. \u00a0\u00a0It then became readily apparent that there were far more than 20 papers worthy to be included, because there was a ridiculous amount of good work put out this year.\u00a0 So, at a certain point we just stopped adding more. \u00a0Some of the work will likely be familiar to anyone used to the photochemical field; however, in our fake scoring system bonus points were given for open access papers and work from new professors.<\/p>

Why 20 papers?<\/strong><\/p>

The year is 2020, I can\u2019t believe you asked this question.<\/p>

Are there 20 papers listed?<\/strong><\/p>

No, there are probably more or maybe less.\u00a0 You\u2019ll need to read and count the entire list to find out.<\/p>

Is there a vote for best photochemistry achievement of 2020?<\/strong><\/p>

No.\u00a0 Awards are stupid.\u00a0 Do you really think we want to deal with running an internet voting poll and awarding photoredox achievement of the year to this?\u00a0 https:\/\/www.youtube.com\/watch?v=vfLZOkn0chc\u00a0<\/strong><\/a><\/p>

Do the links for each article work?<\/strong><\/p>

Sometimes, when formatting an email or a links on website, links go to the wrong place.\u00a0 You can either be confused by this, email us and complain.\u00a0 Or use google and find the correct article.\u00a0 Your choice.\u00a0 Other times, links go to wrong place intentionally and you might find something fun.<\/p>

Do I win a prize if I click on each article?<\/strong><\/p>

You\u2019ll have to click on each article to find out.<\/p>

How do I get my work on the 21 for 2021 list?<\/strong><\/p>

Go here and get to work<\/a>. \u00a0\u00a0Send us the paper once you\u2019ve submitted.<\/p>

In no particular order, here are our 20 favorite photochemistry papers for 2020.<\/strong><\/p>

1: Organocatalyzed Birch Reduction Driven by Visible Light<\/strong><\/em><\/h3>

Our Take:\u00a0 <\/strong>We wrote about this one back here<\/span><\/a>.\u00a0 Just an incredible achievement to find this much reduction potential in a photocatalytic reaction with mild conditions.\u00a0 Unless you prefer running reactions with liquid ammonia.<\/p>
