Abstract |
Phenanthroimidazole-based derivatives have received great attention as promising attractive molecular scaffolds for optoelectronic materials of organic light-emitting diodes (OLEDs), dye-sensitized solar cells, and effective mother-luminophores of fluorescent chemosensors for detecting cations. In order to investigate the photophysical properties of all phenanthroimidazole-triarylborane dyads, density functional theory (DFT) calculations were performed. From the calculation results, we tried to analyze the UV-vis absorption and photoluminescence (PL) spectra obtained from the experiments. The results indicate that the high-energy emission corresponds to π- π* transition of the phenanthroimidazole portion, whereas the low-energy emission origiginates from the intramolecular charge transfer (ICT) transition between phenanthroimidazole and triarylborane moiety. |
