Abstract A novel hexaarylbiimidazole derivative 2,2′‐bis‐(2‐chlorophenyl)‐4,4′,5,5′‐tetra‐[3‐(2‐hydroxyl‐3‐ethylene glycol monoethylene ether‐propane‐1‐oxy)‐phenyl]‐1,2′‐biimidazole (BCTE‐HABI) was synthesized from 3,3′‐dihydroxyl benzil. Ultraviolet spectra, fluorescence spectra, ESR measurements, photo‐dilatometer experiments and photo‐DSC measurements indicated its good UV‐visible absorption ability, high photolysis efficiency and efficient photo‐initiation for acrylates.
