Alternating copolymer of thiophene and N-(phenylethynyl)pyrrole. New pi-conjugated alternating five-membered ring copolymer and its packing structure
An alternating copolymer, Copoly-1, of thiophene and N-(phenylethynyl)pyrrole was prepared by palladium-catalyzed polycondensation. Powder X-ray diffraction (YRD) analysis indicated that Copoly-1 formed a stacked packing structure with doubly-running polymer main chains. Optical data support the molecular and packing structures of Copoly-1. (c) 2005 Wiley Periodicals, Inc.
