摘要: 本文采用EHMO/CO半经验计算方法,以准一维体系对梯形高聚物聚吩噻嗪(简称PTL)本征态及掺杂态电子能带进行了计算,讨论了PTL的导电机理,提出了当掺杂剂为质子酸时的荷电孤子或极化子导电模型及p-型掺杂时的极化子导电模型。

Abstract: In order to study the conduction mechanism of ladder polyphenothiazine(PTL), the electronic energy bands of the eigenstate PTLand doped PTLhave been calculated. In the calculation the polymers are treated as quasi-one-dimensional systems. Th?method of EHMO/CO is used. The results of the energy bands near the fermi level and the net charge density of each models are given. It is sug-estted that for the eigenstate PTLneutral solitons are probably the dominant charge carriers, for pron-tonic acid dopant charge solitons or polarons are the most likely contributors to the conductivity., for p-type doping polarons are the dominant charge carriers. It can be prejudged that the higher conductivity of PTLcan be reached by the means of doubte doping.
