Alkoxylated p-phenylenevinylene oligomers: Synthesis and spectroscopic and electrochemical properties.

Twenty-one n-alkoxy substituted phenylenevinylene oligomers were synthesized, varying in size, number and position of the OR groups. IR,MS and solubility data are presented. NMR measurements provided the molecular structure as well as information about conformations and molecular dynamics. UV and of cyclic voltammetric data give correlations of chemical structure (number and position of OR substituents) with separate HOMO and LUMO energies. (C) 1997 Elsevier Science Ltd.
