摘　　要：为了讨论反应性聚合物结构变化对其光电性能、原位反应及相关应用的影响,提出改变高化学活性菲醌(PQ)的单体卤代位置方法,利用其与双硼酯基芴进行Suzuki偶联,构筑空间结构分别为直线型(L-PPQF)和锯齿型(V-PPQF)的两种活性聚合物.对两类新型反应性聚合物的核磁光谱、红外光谱、紫外荧光光谱、电化学分析及与乙二胺结构原位反应的动力学进行了研究,结果表明,菲醌被成功插入到聚合物主链结构,其反应活性得到了很好的保留;L-PPQF共轭程度明显好于V-PPQF,导致其吸收与荧光光谱明显红移,而还原电位明显升高;活性位点更加裸露的V-PPQF对于低浓度的乙二胺溶液更加敏感,可应用于胺类传感的制备,而L-PPQF更适用于功能性聚合物制备等领域.In order to clarify the effect of the structural change of reactive polymer on its photoelectric properties, in-situ reaction and related applications, a monomer halogenated position method of changing 9, 10-phenanthrenequinone （pQ） with high chemical activity was proposed. With the Suzuki coupling of reactive polymer and diboron-ester based fluorene, two active polymers with the spatial structures of liner shape （L-PPQF） and zigzag shape （V-PPQF） were constructed. Through performing the study on the nuclear magnetic resonance （NMR）, infrared spectrua （IR）, ultraviolet visible and photo-fluorescence spectra （UV-PL）, electrochemical behavior and in-situ reaction kinetics of ethylenediamine structure for the developed reactive polymers, it is noted that the PQ has been successfully inserted into the main chain structure of polymers, and its reactivity is well retained. The conjugated degree of L-PPQF is obviously better than that of V-PPQF, and thus the absorption and fluorescence spectra of L-PPQF are significantly red-shifted and its reduction potential gets significantly improved. The V-PPQF with more naked reactive positions is more sensitive to the low concentration ethylenediamine solution and can be used for the preparation of amine sensing units, while the L-PPQF is more suitable for the preparation of functional polymers.
