Abstract
The doping mechanism and electronic properties of ClO4- in polyacene a re studied by means of quantum chemistry CNDO/2 meth.d. Stable adsorpt ion sites of ClO4- are found over the midpoint of chemical bonds C=C a nd C-C of polyacene molecule, and in the former site larger adsorption energy is given rise to. ClO4- is also easy to migrate towards C=C an d C-C when it is adsorbed on the other sites. It is demonstrated by th e comparison of energy band structures that the doped system has highe r conductivity if ClO4- is adsorbed at the hole site or bridge site of C=C.
