The general reaction of photosynthetic photolysis can be given as H 2 A + 2 photons (light) → 2 e − + 2 H + + A The chemical nature of "A" depends on the type of organism. This application note demonstrates a 230 % increase in throughput on the direct [2+2] cycloaddition of maleic anhydride with ethene to form a cyclobutane motif by using the new Vapourtec’s 365 nm High Power LED. Pilar Prieto, Define photolytic. A synthesis of a library of compounds enables the chemist to rapidly screen possible chemistries and produce small quantities to be used for other screening processes. These features typically result in higher conversions or yields, improved selectivity, enhanced energy efficiencies and reductions of solvent volumes and consequently waste. However, in photochemistry courses it is taught that because the chemistry of the excited singlet and triplet states are added to that of the ground state excitation by light multiplies by 3 the accessible reaction paths.
