Rs. Wang et al., THEORETICAL-STUDY ON THE DOPING MECHANISM AND ELECTRONIC-PROPERTIES OF CLO4- IN POLYACENE, Synthetic metals, 57(2-3), 1993, pp. 4531-4535
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.
