Abstract

Thanks to their chemical, thermal, photophysical, and photochemical properties, phenanthroimidazole derivative compounds attract attention in optoelectronic device technology, especially in OLEDs. For this reason, phenanthroimidazole derivatives are the most promising compounds for these applications in the future. In this study, the -diCl bearing phenanthroimidazole compound was synthesized, characterized, and investigated in detail the photophysical and aggregation properties. Spectroscopic studies for its characterization used 1 H-NMR, ATR-IR, and detailed LCMS-MS (mass and product ion scan). The absorption and emission spectra of diCl-PHN have been recorded with solvents of different polarities at room temperature. diCl-PHN exhibit high fluorescence quantum yield in DMSO with 0.78. CIE chromaticity diagram results of diCl-PHN were obtained and displayed good intensity. Additionally, aggregation properties were recorded at seven different water concentrations (water/DMSO %). With the results obtained from the study, it was concluded that this phenanthroimidazole derivative compound is a suitable molecule for fluorescent applications.
