## Abstract **Summary:** A highly fluorescent photochromic polymer, polyโBTFO4, was prepared. The fluorescence quantum yield of the polyโBTFO4 was six times higher than that of BTFO4. Fatigue resistance of the polymer at its photostationary state was significantly enhanced compared with that of BTF

## Abstract **Summary:** Photoorientation processes in two cholesteric mixtures were studied. Mixture I contained a nematogenic phenylbenzoate homopolymer, a photochromic diarylethene dopant and a chiral dopant. Mixture II consisted of a binary combโshaped nematogenic copolymer with fluorescent per
## Abstract In comparison with poly(9,9โdialkylfluorene)s widely used in organic optoelectronic devices, poly(9,9โdialkylfluoreneethynylene)s (**PFEs**) have attracted less attention partly because of their poor fluorescence quantum yield (FQY) in the solid state. In order to improve the FQY, a 1,4
