Article abstract of DOI:10.1021/j100139a022

Various α,ω-disubstituted polyenes of increasing length and bearing various donor and acceptor end groups have been synthesized in order to investigate the chain-length dependence of their second-order hyperpolarizability γ.Both symmetric polyenes bearing
