英文摘要: Abstract(#br)Manipulating the sub-units of conjugated co-polymers was a convenient and promising strategy for developing novel functional materials. Here a soluble alternating copolymer (P-Boc) consisted of 9,9-dialkylfluorene and 1,4-diketo-2,5-di( t -butoxycarbonyl)-3,6-diphenyl-pyrrolo[3,4- c ]-pyrrole was designed and synthesized. Heating the spin-coated P-Boc film could afford an insoluble polymer film (P-2H) with multiple lactam hydrogen units by the removal of the t -butoxycarbonyl groups. Unlike the small molecules with lactam hydrogen, the P-2H film was insoluble and exhibited the remarkable naked-eye visible color change and a new long-wavelength absorption band in the fluoride anion-containing organic solution. The naked-eye visible and spectroscopic detection limits for...
