Abstract

1998 electron spectra, ESCA electron spectra, ESCA (organic substances) K 2515 -043Syntheses and Properties of Unsymmetrically Substituted Bi-and Quaterthiophenes.-In continuation of an earlier investigation concerning the molecular design for enhancement of the polarizable structural properties in this study unsymmetrical compounds of type (I) and (II) are synthesized. The electronic absorption spectral behaviors of these derivatives compared to symmetrical compounds is discussed. -(HIGUCHI, H.; URAKI, Y.; YOKOTA, H.; KOYAMA, H.; OJIMA, J.; WADA, T.; SASABE, H.; Bull.
