摘要: In the second part of this review we highlight bimolecular reactions (hydrogen abstraction, and energy or electron transfer) that take place in photochemistry poly(organophosphazenes). Both inter-molecular interactions (i.e. between excited free chromophores ground state groups attached to phosphazenes, phosphazene substituents external quenchers) intra-molecular processes geminally same phosphorus supported different along polyphosphazene skeleton) are exploited. Suggestions given on possible practical application these photochemical domains, e.g. heterogeneous-phase photosensitization, photocrosslinking, photoconductivity, microelectronics, light-induced radical polymerization vinyl monomers, etc.
