LASER-ENHANCED ELECTROCHEMICAL DOPING OF POLY (N-VINYLCARBAZOLE)

引用

chinese Chemical Letters 1994年第9期5卷 791-794页

作者： yan Ling LI Jun Hui yanG {2. Ren XU(institute of Physics. chinese Academy of sciences, beijing 100080)

Laser-electrochemical doping of poly(N-vinylcarbazole) (PVK) leads to the formation of high conducting PVK polymers. The doped polymers were characterized by IR spectra and electrical conductivity measurement. The results show that the photochemical effects from laser irradiation on the working electrode speed up the reaction rate and increase the doping degree of counterion.

作者： ji min {2. Xue Qi YI institute of chemistry. Academia Sinica, beijing 100080 Graduate School Academia Sinica, beijing 100039

The frontier orbitals HOMO and LUMO of the fullerene C_(60) has been given in a system of 60 motion-coordinates, of which each origin is at each C atom of fullerene C_(60) and each z-axis is in the direction perpendicular to C_(60)'S spherical surface. In this motion-coordinate system the HOMO and LUMO of fullerene C_(60) obviously display characteristics of spherical n-molecular orbitals π_n. The Fenske-Hall quantum-chemical method is used in calculation for the electronic structure of the fullerene C_(60).
