Exploration of efficient fluorescent, charge transfer, and energy harvesting materials based on the synthesis of well-defined helical polymers

合成了侧链上含芘的聚（喹啉-2,3-二基）。芘准分子的螺旋感选择性和荧光强度随溶剂的不同而发生显著变化。此外，还制备了具有氯辛基和(s)-2-甲基丁基侧链的聚（喹啉-2,3-二基）s。由多喹啉制备的薄膜在可见光区表现出选择性反射。溶剂退火后，聚合物薄膜的反射行为随溶剂的变化而变化。

Poly(quinoxaline-2,3-diyl)s bearing pyrene units at their side chains have been synthesized. Helix sense selectivity and fluorescence intensity, which originated from pyrene excimer were dramatically changed depending on their solvents. Furthermore, poly(quinoxaline-2,3-diyl)s having chlorooctyl and (S)-2-methylbutyl side chains were also prepared. Thin films fabricated from the polyquinoxaline exhibited a selective reflection in the visible region. After solvent annealing, the reflection behavior of the polymer film was changed depending on the solvent.
