Outline of Final Research Achievements

The fused azobenzene-boron complexes (BAzs) were prepared, and highly efficient near-infrared (NIR) emission was observed from the nitrogen-nitrogen double bond (N=N) containing conjugated copolymer. From the optical measurements, it was found that BAz worked as a strong electron-acceptor originating from intrinsic electron deficiency of the N=N double bond and the boron-nitrogen (B-N) coordination. The simple donor-acceptor (D-A) type copolymer with bithiophene and BAz exhibited intense photoluminescence in the NIR region both in the dilute solution and in the film. We expected that the properties lead to an application to emissive polymer devices.
