Searching for the origin of life with a 365nm LED (with photoredox organocatalysis) How did life begin? Were the first catalysts, photocatalysts? Was an LED involved? What is it like doing chemistry on a meteor? What came first, the chicken or the egg? We’ll answer some or none of these questions this month, when we discuss the recent Account by Oliver Trapp and coworkers on their work in prebio..

Setting Up Your Initial Photochemistry Reactions This is the third and final part of a three part series designed to help you get started by understanding light sources in photochemistry. Missed the start of the series where we cover the basics and core principles? No worries, you can read it here… Visible light photoredox catalysis uses the excited states of metal complexes and organic dyes to ..

Part II: Understanding and Measuring Light Sources This is the second part of a three part series designed to help you get started by understanding light sources in photochemistry. Missed the first part of the series where we cover the basics and core principles? No worries, you can read it here… The ease in setting up photochemical reactions led to a rapid adoption of photoredox chemistry. Much..

A few weeks ago, we discussed the history of the Lucent360™, our new photoreactor for light and temperatures control for screen to scale, in both batch and flow. This month, we want to share a series of experiments that demonstrate the value of the Lucent360™ for studying a photochemical reaction. This project was brought to us by chemists at the IRCOF and Oril in France*. There is no shortage o..

We typically send out a year-end review of our favorite photochemistry papers every January. We really enjoy putting together that list, although we always have significantly more papers that we like than spots on the list. That list ends up being heavily biased towards papers published towards the end of the year. As a remedy, we thought a nice lazy midsummer activity would be to update our fav..

We are huge fans of what could be classified as “creative photocatalysts”. One of our favorite papers over the past few years was this work that we wrote about here using Hypericum flowers as an organic dye for C-C bond formation. A few dried flower petals, a base and an LED and you have a new photochemical reaction. So, if your paper can be described as using a “Fenton Boat photocatalyst”, well..

This month, we highlight the recent work of several students from the Balasubramanian Lab at the University of Cambridge using the EvoluChem™ Photoredox Boxes in their graduate studies. Shankar Balasubramanian is a godfather in the field of nucleic acid chemistry and methods to sequence epigenetic modifications. In recent years this work has involved visible-light applications. Ben Mortishire-Sm..

다양한 광원 사용 가능 빛을 고르게 분산시키는 광화학 챔버 표준 교반 플레이트 사용 가능 최대 32개 반응 조건 실험 가능 촉매 및 시약 사용 가능 Our original photoreactor’s patented design is compatible with most vial formats (0.3 ml, 2 ml, 4 ml and 20 ml vials) as well as most stirring plates. A built-in fan keeps the reaction conditions at room temperature. Several light source options are available. PhotoRedOX BOX 더 자세한 정보는 켐코코리아로 문의하세요~! 켐코코리아 주식회사 Tel..

Introducing the Lucent360™ Advanced Photoreactor The Lucent360™ Advanced Photoreactor enables parallel (screen), batch and flow with wavelength,light intensity and temperature control in one device. Multiple vial formats and configurations (from 0.3ml to 700 ml) Temperature controlled (0° to 80° C) with thermostatic fluid Interchangeable LED light modules (365 nm through 525 nm) Screen up to 4 w..

This month we decided to summarize the Ni cross-coupling photocatalysis literature in a short review. But we quickly realized that’s a terrible idea, because a. it’s a lot of work, b. does not sound all that fun, and c. has been done, repeatedly here, and here. Also, here. This is a long one. This is a short one. This one is in flow? This one is open access . This one’s just right. Instead, we d..
