以AIE活性基团调控手性高分子在聚集诱导下AICPL材料为研究主线，选择联萘酚、联萘胺、环己二胺、Salen-Zn(II)、Salen-(BF2)2配合物等为手性单元，以四苯乙烯(TPE)、二苯芴乙烯、1,-4-二氢吡啶/吡喃衍生物、硼杂氮代β-二酮-(BF2)2等AIE活性基团为连接体，通过Pd催化偶联反应，合成结构规整、高度有序的D-π-A/D-A型的手性高分子和高分子配合物。通过改变不良溶剂比例，使手性高分子聚集诱导后荧光强度急剧增大(AIE)，同时产生较强聚集诱导偏振荧光(AICPL)发射信号。通过在手性共轭高分子引入不同的donor与acceptor结构基团，产生空间效应和电子诱导效应，改变高分子能级带隙，调控CPL发射波长，并提高荧光量子效率。通过手性结构基团、AIE活性基团与高分子共轭骨架结构间相互作用，产生协同放大效应，提高偏振荧光各向异性的r值和AICPL的gem值。

This program is mainly focused on investigation on tunable AICPL emission materials based on AIE-active chiral polymers. Herein, binaphthol, binaphthyladiamine, diaminocyclohexane, salen-Zn(II), salen-(BF2)2 chosen as chiral units, and tetraphenylethylene(TPE), 9-(diphenylmethylene)-9H-fluorene, 1,4-dihydropyridine/pyran derivatives, aza-β-diketonate as AIE-active linker unit, regular and well-ordered D-π-A/D-A type chiral polymer or chiral polymer complexes can be synthesized by Pd-catalyzed cross-coupling reaction. Aggregation-induced circularly polarized luminescence (AICPL) signals of chiral polymers in the aggregate state can be greatly enlarged by changing poor solvent fraction. Low band gaps, tunable AICPL emission wavelength and high fluorescence quantum efficiency can be improved by introducing different donor and acceptor groups into chiral polymer main chain backbone. The interaction among chiral unit, AIE-active chromophore and conjugated polymer chain backbone structure can produce the synergic chirality enlargement effect, which leads to the increase of the anisotropy r and AICPL gem values.
