Binaphthol and its derivatives have the characteristics of C2 axis asymmetry, modified sites, and highly stable chiral configuration, and are widely used in molecular or ion recognition, organic electroluminescence (OLED), nonlinear optics and molecular machinery The field of functional materials has been extensively studied and demonstrated a good application prospects. In this paper, based on the different molecular structure of binaphthol derivatives photoelectron functional materials, the design principles, modification methods and applications of the structural modification were summarized. The relationship between the structure and the photoelectric properties of each site modified materials was reviewed: single site and multiple site Modified binaphthol mainly through hydrogen bonding, photoinduced electron transfer (PET) and other mechanisms to achieve molecular or ion recognition, and more used in fluorescent chemical sensors; double-site modified binaphthol, mainly the use of reverse non-planar Structure and π-conjugate properties are widely used in OLEDs. In the same way, binaphthol derivatives have also shown good applications in nonlinear optics and molecular machinery based on the C2 axis asymmetry and chiral induction properties . Finally, the research and development direction of binaphthol photoelectric functional materials are prospected.
