Spectral properties of carbazole-containing polymers with phosphore groups in the main chain

Abstract

The absorption, fluorescence and phosphorescence of the carbazole-containg polymers with phosphore groups in the main chain of two types and without spacer were studied. It was shown that spectral properties of pf2-sep polymer are connected mainly with optical transitions in individual carbazole chromophores. The optical properties of pf2-conj polymer are rather different comparative to the pf2-sep. That is caused by perturbation carbazole groups electron system by phosphor-groups and influence carbazole groups each other. This perturbation takes place under special relative geometrical displacement of carbazole and phosphor groups.
