Abstract

Abstract : Poly(xanthon-3-yl methacrylate) having a π-stacked conformation efficiently harvests photo excitation energy for sky blue phosphorescent emission of iridium bis[(4, 6-difluorophenyl)pyridinato- N, C 2 ]picolinate (FIrpic) in solution and in film. Abstract : Poly(xanthon-3-yl methacrylate) (poly(XOMA )) and poly(xanthon-3-yl methacrylate- co -methyl methacrylate) (poly(XOMA - co -MMA )) having a π-stacked conformation were synthesized as host material candidates for phosphorescence-based light emitting diodes. Poly(XOMA ) harvested photo excitation energy for blue phosphorescent emission of iridium bis[(4, 6-difluorophenyl)pyridinato- N, C 2 ]picolinate (FIrpic) in a CHCl3 solution and in film.
