Four heterocyclic hexaarylbiimidazoles, BFuTM‐HABI, BThTM‐HABI, BCTFu‐HABI, and BCTTh‐HABI, were synthesized to improve the UV‐vis absorption properties of hexaarylbiimidazoles. UV‐vis spectra, fluorescence spectra, ESR measurements, photo‐dilatometer experiments, and photo‐DSC measurements indicate that BCTFu‐HABI and BCTTh‐HABI exhibit better UV‐vis absorption abilities and photoinitiation activities for acrylate derivatives with different functionalities than BFuTM‐HABI and BThTM‐HABI, respectively. © 2007 Wiley Periodicals, Inc.
