Abstract
Quantum yield of a photo-reactive materials are defined as the rate of the product formation over the sum of various deactivation process rates, which is usually regarded as identical to the molecule, because the quantum yield of the photoreaction is described according to the photo-physical process. The quantum yield of the photo-reaction in solid state polymer is not only determined by the photo-physical, however, but also by the effect of free volume of polymer matrix. Therefore the quantum yield of photo-reaction of photo-reactive molecule in solid state polymer has inhomogeneous distribution. We have determined the quantum yield distribution of a photo base generator (PBG) to find that the PBG is much reactive in solid state polymer than in solution. The reason is well explained by the dynamic free volume concept.
