Photochemistry is taking dominating the field of synthetic chemistry. That’s a bit much, I guess. Making intriguing and significant molecules in ways that may be simpler, safer, or even unattainable using standard thermal processes is achievable through the use of photochemistry, which is a truly cool science. Okay, that’s better. In this discussion, the term “photoredox catalysis” refers to catalytic reactions that are in some way triggered by visible light. Today’s chemical journals contain many innovative methods that use visible light as the main reagent in a chemical reaction.
You might have assumed this was a fad because we make fun of the microwave, or you might just truly enjoy your oil bath (weird). However, if you’ve never worn a pair of hip orange glasses, activated a brilliant blue LED, and pointed it at a reaction flask, you’re missing out. If you’re lucky, photochemistry will bring you many hours of pleasure and millions of bucks. In all seriousness, the objective of this 3-part series is to introduce you to the basics of photochemistry and provide you with the information you need to get started. Light comes in three primary categories: Visible (from 380 to 700 nm), visible light (between 100 and 380 nm), and infrared (greater than 700 nm). Longer wavelengths have substantially less energy than shorter wavelengths, which have more energy. UV radiation has the power to initiate free radical reactions and radical rearrangements and is strong enough to directly disrupt chemical bonds. Synthetic uses can be made of conventional processes, such as photocycloadditions of,-unsaturated ketones to alkenes. However, this aggressiveness drastically lowers the tolerance for functional groups. Although UV light does not penetrate deeply into the skin, it has enough energy to directly damage DNA and result in severe sunburn. What is generally referred to as “heat radiation” is the weakest wavelength, infrared, which is invisible to the human eye. Infrared radiation is useful chemically for isomerization’s, cleavage processes, and the activation of prodrugs in vivo. It is emitted and absorbed by molecules during rotations and vibrations. Red light has the highest transmission efficiency and is least susceptible to material absorption. Between these two extremes lies visible light, the kind that can be seen with the naked eye. Nearly all of the energy used by living things on Earth originates from photosynthesis, which converts visible light into carbohydrates [1-4].
The majority of the chemicals in our environment, fortunately, do not absorb much light, and when they do, not much happens. Visible light is generally not very sensitive to most objects. Otherwise, your Tylenol bottle can have a limited shelf life and your morning cup of coffee might have a little too much reactivity. To chemically access the energy that is seen from light in our reaction, the photon must be absorbed by something. We frequently need a specific type of molecule, such as metal complexes with large aromatic ligands or strongly conjugated organic dyes, with strong absorbance bands in the visible region. Photosensitizers are substances that can transfer light-excited energy into another item. For our purposes, these serve as our photocatalysts.
