The spectral properties of some carbazole-containing polymers with phosphore groups in the main chain

The absorbtion, fluorescence and phosphorescence of the carbazole-containing polymers with phosphore groups in the main chain of two types (carbazole chromophores are separated with spacers (pf(2)-sep) and without spacer (pf(2)-conj)). were studied. It was shown that spectral properties of pf(2)-sep polymer are connected mainly with optical transitions in individual carbazole chromophores. The optical properties of pf(2)-conj polymer are rather different comparative the pf(2)-sep. That, is caused by perturbation carbazole groups electron system by phosphor-groups and influence carbazole groups (belong to the same unit) each other. This perturbation takes place under special relative geometrical displacement of carbazole and phosphor groups.
