“…Compounds with 1-phenyl-1 H -benzimidazole skeleton 1 have gained attention for a long time and been studied for the applications of platelet-derived growth factor receptor (PDGFR), 2 cyclooxygenase (COX), 3 and phosphodiesterase 10A 4 inhibitors, as well as for many optoelectronic materials. 5 N -Aryl-1,2-phenylenediamines are also important for synthesizing various benzimidazole derivatives, and 1,3,5-tris( N -phenyl-benzimidazol-2-yl)benzene (TBPI) is an important electronic material for OLED applications that is still widely used nowadays. 6 …”
