This technology introduces alkoxy flexible segments terminated with carbazole into poly(diarylfluorene) backbones via a rod-coil copolymer strategy, achieving intrinsic polymer flexibility. Single-chromophore exciton regulation enhances charge transport efficiency, while interchain interpenetration structures ensure uniform deep-blue emission even after film stretching. Flexible light-emitting diodes based on this exhibit deep-blue emission meeting NTSC standard blue specifications.
