  Low-Bandgap Benzodifuranone-Based Polymers

  摘要：

  pi-Conjugated monomers and polymers containing benzodifuranone units in the main chain were prepared. Polymers were obtained using palladium-catalyzed Suzuki and Stifle polycondensation reactions of dibromo-substituted benzodifuranone derivatives with either dihexylfluorene diboronester or bis(trimethylstannyl)thiophene. The optical and electronic properties were investigated using UV/vis absorption spectroscopy and cyclic voltammetry. It was found that the polymers show very broad absorption bands with a high extinction coefficient up to 32500 L mol(-1) cm(-1). The polymers also show reversible redox behavior, giving small HOMO-LUMO gaps up to 1.30 eV with strong donor-acceptor character.

  A stimuli-responsive color-changing functional coating is prepared from the following raw materials: an epoxy resin, a furanone pigment, an amine curing agent, and a solvent. The furanone pigment is an organic conjugated conductive molecule. The amine curing agent reacts with the furanone pigment to form a cross-linked molecule containing a hydrogen bond that can exhibit excellent electron transition behaviors. Moreover, as the cross-linked molecule is unstable, it may give rise to electron transitions with different properties under different stimulus conditions, imparting a color-changing property to the coating that allows the coating to have different colors in response to different environmental stimuli. Experimental results show that the stimuli-responsive color-changing functional coating in the present invention has thermochromic, ultraviolet-photochromic and strongly acidochromic properties, and is responsive to diverse color-changing stimulus conditions with a wide color-changing range.
