低带隙有机导电聚合物的设计及应用

Design and application of organic conductive polymers with low-band-gap

由于有机导电聚合物特殊的电、磁性质,从20世纪70年代被发现以来,一直受到广泛的重视。拥有低带隙的有机聚合物在基态就能显示本征导体或半导体性质,因此低帯隙是这类化合物一个重要的追求目标。介绍了有机导电聚合物的概念、种类;如何设计具有低带隙的有机导电聚合物;以及在太阳能电池、发光二极管、电磁屏蔽和气体传感器等方面的应用;并对其未来研究的发展趋势进行了展望。

The organic conductive polymer has aroused great attention because of the especial electronic and magnetic properties, since it was found in the 1970s. The polymer with low band gap exhibited intrinsic conduction or semieonductive properties even in ground state, so obtaining low band gaps was an important goal to study such polymer. The definition and types of the polymer were introduced. The method to design those compounds with low-band-gap was studid, and the utilization in solar cell,light emitting diode,electromagnetic shielding and gas sensor, and the prospect of research the polymer were pointed out.
