摘要

A method of the synthesis of a new generation of polymers with intrinsic llorescence-poly(Shiff's bases)-bifluorophores-was developed. These polyniers con. lin two different fluorophores in each unit of the main polymer chain. One of the lOrescent fragments is a donor of electron excitation energy and the second one is an :ceptor. The photophysical properties of poly(Shiff's bases)-bifluorophores were in- ~stigated. It was shown that in poly(Shiff's bases)- bifluorophores nonradiation energy ansfer along the polymer chain in the solid and liquid solutions of polymers takes ace. The influence of the disposition of fluorophores in the polymer chain and the stance between them on nonradiation energy transfer were investigated. It was town that the maximum nonradiation energy transfer is realized in polymers-biflu- ophores with a statistical distribution of the fluorophore fragment in the polymer lain. The influence of the distance between a donor and an acceptor of the electron :citation energy on the nonradiation energy transfer was investigated. It was estab- ;hed that nonradiationenergytransfer is not observed if the distance between a donor Id an: acceptor of energy exceeds 10 nm.
