Donor Acceptor

A donor/acceptor/donor-type benzoselenadiazole-incorporated monomer was synthesized. The procedure described herein offer several advantages, including high product yields, easy purification and large scale production. Optical properties of the resulting compounds were examined by means of UV-vis and fluorescence spectroscopies. The fluorescence spectra exhibit that the emission maxima of material at 419 nm belongs to blue light region.

Donor Acceptor

Novel donor-acceptor conjugated organic molecules composed of central fluorene and phenothiazine units and aldehyde terminal groups have been designed and constructed via the Vilsmeier-Haack reaction. Optical properties of the resulting molecules were examined by UV-vis and fluorescence spectroscopies. The fluorescence spectra of the molecules in the solid state show strong emission peaks in the violet, blue, cyan and green light regions. Thus, the molecules are expected to be promising light-emitting materials for organic light-emitting diodes applications.
