Abstract
2-(4-(4-(hydroxymethyl)-1H-benzo[d]imidazol-2-yl)-1H-benzo[d]imidazol-2-yl)phenol was synthesized with(2,3-diaminophenyl) methanol prepared from 3-methylbenzene-1,2-diamine as the raw materials,through amino protection,bromide,hydrolysis reaction,oxidation and condensation.The molecular structures of the intermediates and the target compound were confirmed by 1H-NMR.UV and fluorescence properties of end product were researched,the results show that the compound can be coordinated with Zn2+,resulting in strong fluorescence,fluorescence quantum yield of 0.64,Stoke's shift of 142nm.
