Three new alternating conjugated polymers consisting of pyrene and 3‐dodecylthiophene (PPyMT), 4,4′‐didodecyl‐2,2′‐bithiophene (PPyBT), or 9,9‐didodecylfluorene (PPyFlu) moieties have been prepared using Suzuki coupling reaction or Sugimoto approaches. The polymers were readily soluble in common organic solvents and exhibited good thermal stability in nitrogen and air atmospheres. The structures and
三个选自芘和3-十二烷基(的新交替共轭聚合物PPyMT),4,4'-双十二烷基-2,2'-二噻吩(PPyBT),或9,9- didodecylfluorene(PPyFlu)部分已经使用Suzuki偶联反应来制备或杉本的方法。该聚合物易溶于常见的有机溶剂,并在氮气和空气气氛中表现出良好的热稳定性。聚合物的结构和光学性质通过NMR,FTIR,XRD,UV-vis和荧光光谱进行了表征。PPyMT和PPYBT在溶液中显示蓝光发射,而PPyFlu在胶片状态下发出蓝光。由于pyr-pyπ-π堆积相互作用,聚合物表现出分子间聚集和结构有序性。©2010 Wiley Periodicals,Inc.
