The study on the conducting properties of poly-para-phenyl and substituted poly-para-phenyl

The conductive property of polymer is decided by Eg and BW, which are concerned with its structrue, the effect of side groups, etc. has a large effect on the Eg and BW. In this paper, by AMl and EHMO/CO method, the one-dimensional energy band structure of poly-para-phenyl and a series of substituted polymer are calculated, we discuss the influence of different kinds of substiuent group on poly-para-phenyl conductive property.
