Notes:
By means of the valence effective Hamiltonian (VEH) method, we calculated the electronic structure for a polymer containing poly(para-phenylene vinylene) (PPV) and dimethoxy-poly(para-phenylene) (PPP) units as well as silicon atoms used as spacers. The equilibrium geometry was obtained by an AM1 calculation. We obtained a band gap of 3.2 eV, which corresponds to emittance in the blue part of the spectrum. This polymer is used as the active layer in light-emitting diodes. © 1997 John Wiley & Sons, Inc.
