摘要

The photophysical behaviors of the oligomer based on 1,1'-binaphthol with 3,3'-acetylene spacer were investigated. The oligomer molecule has a naphthyl-acetylenenaphthyl effective conjugation segment. The atropic of the 1,1'-binaphthyl moiety led to twisted and rigid main chain in the oligomer. With the changes of the external environment such as solvents used, solvent viscosity and ambient temperature, the wavelengths of absorption and the intensities of fluorescence and absorption are changed slightly, but the fluorescent intensity and quantum yield can be influenced. The luminescent behaviors of the oligomer exhibit twisted intramolecular charge transfer characteristics, which could have a potential application in wavelength-stable light emitting material adaptable to ambient temperature and the solvents used in wide range.
