| Abstract: | A blue luminescent material named QCC that contains quinoline and coomarin units was synthesized. The photophysical property of QCC was investigated by the UV-vis absorption and fluorescence emission spectra, which indicates that QCC can emit blue light. With the increase of polarity of solvents, the emission wavelength of DCC shows an obvious red-shift. Besides, we investigated the interactions between QCC and electron donor N, N'-dimethylaniline(DMA), electron acceptor(DMTP)using fluorescence quenching technique, which demonstrates that QCC has excellent electron transfer property. At the same time, the interactions of QCC with C70 and CNTs were also investigated to confirm the above property, respectively. The electrochemical property and energy levels of QCC were calculated by Gaussian 09 software, and the results basically conform with the data measured by cyclic voltammetry method.Thermal stability study reveals that QCC has good thermal stability with thermal decomposition temperature(td)of 270 ℃. These results indicate the QCC has the potential in the construction and application of blue organic light emitting diodes(OLEDs). |
