Synthesis and Optical Properties of Donor-Accepter Organic Conjugated Molecules Composed of Fluorene and Phenothiazine

Abstract:

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.
