摘要
联萘酚及其衍生物具有C2轴不对称性、修饰位点多、手性构型高度稳定等特点,在分子或离子识别、有机电致发光(OLED)、非线性光学以及分子机器等光电功能材料领域得到了广泛研究并展现出良好的应用前景。本文依据联萘酚衍生物光电功能材料分子结构的不同,总结了其结构修饰的设计原理、修饰方法及其应用,评述了各位点修饰材料的结构和光电性能的关系:单位点及多位点修饰的联萘酚,主要是通过氢键作用、光诱导电子转移(PET)等机理实现分子或离子识别,多应用于荧光化学传感器;双位点修饰的联萘酚,主要是利用扭转非平面结构和π共轭特性等调节光电性能,广泛应用于OLED;同样,基于C2轴不对称性和手性诱导特性,联萘酚衍生物在非线性光学以及分子机器等领域也展现出良好的应用。最后,展望了联萘酚类光电功能材料的研究和发展方向。
Chiral binaphthol derivatives （ BINOLs） have recently attracted considerable attention as active materials in photoelectric applications,such as sensors,organic light-emitting diodes （OLED）,nonlinear optics, and molecular machines,due to their particular C2-unsymmetry,polysubstitution and stable chiral conformation. In this review,the design strategies and applications of BINOLs are summarized according to their different molecular modification methods. The relationships between structures and optoelectronic properties are also elucidated. Monosubstituted and polysubstituted BINOLs are mainly applied to fluorescent sensors based on photo-induced electron transfer （PET） and hydrogen bond interaction mechanisms. Disubstituted BINOLs are widely used in OLEDs,due to their outstanding optoelectronic properties that can be adjusted by changing the conformation and conjugation of the twisty π-conjugated naphthalene of BINOLs. There are also many other applications,such as in nonlinear optics and molecular machines grounding on the C2-symmetric and chiral character of BINOLs. Further development and prospects of BINOLs are also discussed.
