New blue light emitting polymers having the characters of PPP and PPV
The new blue light emitting conjugated polymers. PBPV and PTPV having advantages of both PPP and PPV have been synthesized by Suzuki coupling reaction and nickel-catalyzed coupling reaction. The obtained polymers showed good solubility. PTPV has more good thermal stability than that of PBPV. The photoluminescence spectra of PBTV and PTPV showed the maximum at 460 nm and 450 nm, respectively. The optical energy band gap of PBTV and PTPV were 2.93 eV and 2.98 eV, respectively.
