Synthesis of New Donor-Acceptor Diarylacetylene Chromophores and Preparation of Corresponding Nonlinear-Optical Side-Chain Polymers
New donor-acceptor substituted diarylacetylene hyperpolarizable chromophores bearing an amino group as donor and a methylsulfonyl group as acceptor at each extremities of an azatolane conjugated path have been designed to get a good nonlinearity-transparency trade-off, and synthesized. Corresponding methacrylate esters have been obtained then submitted to free radical polymerization, leading to novel side-chain nonlinear optical polymers and copolymers.
