Photoaddition 意味

WebAug 4, 2024 · Photolysis is also called photo fragmentation or photodissociation, or photodecomposition. It is a chemical reaction in which photons break down molecules of a chemical compound. It is one or more photons interacting with a single target molecule and is not limited to visible light. Flash photolysis is an example of photo-dissociation. WebThe photoaddition reactions systematically studied by De Schryver6 and Hasegawa7 are basically different from these photoinitiated polymerizations. Here the polymer is not formed by a chain mechanism but by a step mech-anism, i.e. each step of addition requires a new photoprocess. The same is
