PHOTOPHYSICAL BEHAVI0RS OF OLIGOMER BASED ON 1, 1′-BINAPHTHOL WITH 3, 3′-ACETYLENE SPACER*

Received Date: 6 September 1997

The photophysical behaviors of the oligomer based on 1,1'-binaphthol with3,3'-acetylene spacer were investigated. The oligomer molecule has a naphthyl-acetylene-naphthyl effective conjugation segment. The atropic of the 1,1'-binaphthyl moiety led totwisted and rigid main chain in the oligomer. With the changes of the external environ-ment such as solvents used, solvent viscosity and ambient temperature, the wavelengthsof 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.
