Hexaarylbenzenes (HAB) and their derivatives have attracted considerable attention due to fantastic molecular geometry various applications in materials science. Herein, a set of novel, pyrene-based, asymmetric hexaarylbenzene molecules 3a–c 10 were synthesized fully characterized by using 1H/13C NMR, single crystal X-ray diffraction, high-resolution mass spectra (HRMS), UV–Vis fluorescence spe...
