Two-photon absorption properties of heterafluorenes and spirobiheterafluorenes bearing aminostyryl arms

Abstract

A phosphoniafluorene and a spirobiphosphoniafluorene bearing 4-(diethylamino)styryl groups were synthesized. These compounds exhibited bathochromically shifted absorption and emission, compared with their silicon analogues, because of the strong acceptor property of the phosphonium core. They also showed enhanced two-photon absorptions at around 930 nm.
