两亲性棒卷化合物具有优异的光物理性质，可以在水或极性溶剂中组装成不同尺寸的超分子纳米结构。在此，我们合成了以9,10-二苯乙烯基蒽（DSA）为核心、以萘单元为端基、通过四甘醇链连接DSA的两亲性化合物2N-DSA 、 4N-DSA和6N-DSA 。这些化合物在水溶液中具有优异的聚集诱导发射（AIE）特性，并组装成蠕虫状碎片或不同尺寸的球形组件，从而保证了棒与线圈段的体积比。值得注意的是，DSA 与缺电子化合物 2,4,6-三硝基苯酚 ( TNP )、2,4,5,7-四硝基芴酮 ( TNF ) 和四乙二醇二硝基苯甲酸酯 ( TGDNB ) 之间的供体-受体相互作用形成电荷转移复合物，它可以作为纳米反应器，将Suzuki偶联反应的产率提高约8-10倍。实验结果表明，供体-受体、分子间π-π堆积以及疏水-亲水相互作用的协同效应显着影响聚集体的形态和纳米反应器的效率。

Donor–Acceptor Assembly of Amphiphilic Molecules Based on 9,10-Distyrylanthracene Derivatives with Terminal Naphthalene Groups

Amphiphilic rod–coil compounds have excellent photophysical properties and can be assembled into supramolecular nanostructures of different sizes in water or polar solvents. Herein, we synthesized the amphiphilic compounds 2N-DSA, 4N-DSA, and 6N-DSA with 9,10-distyrylanthracene (DSA) as the core and a naphthalene unit as the terminal group that connected DSA through a tetraethylene glycol chain. These compounds have excellent aggregation-induced emission (AIE) properties in aqueous solution and are assembled into worm-like fragments or different sizes of spherical assemblies, defending the volume ratio of the rod to coil segments. Notably, the donor–acceptor interaction between DSA and electron- deficient compounds 2,4,6-trinitrophenol (TNP), 2,4,5,7-tetranitrofluorenone (TNF), and tetraethylene glycol dinitrobenzoate (TGDNB) forms a charge transfer complex, which can be used as a nanoreactor to improve the yield of the Suzuki coupling reaction about 8–10 times. The experimental results reveal that the synergy effect of the donor–acceptor, intermolecular π–π stacking, and hydrophobic–hydrophilic interactions significantly influences the morphology of aggregates and the efficiency of the nanoreactor.
