N1 - Funding Information:
The authors would like to seize this opportunity to thank warmly Professor Giuseppe Zerbi for many stimulating discussions and for his never-tiring enthusiasm. The Mons-Liège-Leuven collaboration is conducted in the framework of the Belgian Federal Government Services of Scientific, Technical, and Cultural Affairs “Pôle d'Attraction Interuniversitaire en Chimie Supramoléculaire et Catalyse”. Thierry Kogej is holder of a FRIA fellowship. Eric Hendrickx and Stephan Houbrechts are Research Assistants and Koen Clays is Senior Research Associate of the Fund for Scientific Research—Flanders (FWO-V). This research in Leuven was supported by research grants from the FWO-V (FWO-V G.0338.98 and G.0407.98) and the University of Leuven (GOA/95/01) and that in Mons by the Belgian National Fund for Scientific Research FNRS-FRFC.

N2 - We present a joint theoretical and experimental investigation of the second-order nonlinear optical properties of a new kind of active molecule with a triblock structure. The molecular architecture is such that two highly polarizable conjugated segments are separated from each other by a spacer; one of the conjugated segments is end-capped with an electron-donor group, the other one by an acceptor. E-vinylthiophenes are used as the conjugated segments; N,N-dimethylaniline and nitrophenyl are selected as the donor- acceptor pairs, while the spacer consists of a nonconjugated moiety. Several spacers are considered and discussed with respect to their ability to modulate the charge transfer between the donor and acceptor ends. (C) 2000 Elsevier Science B.V.
