Abstract
Herein, we report a novel approach for the synthesis of Ï-conjugated peptide-based donor-acceptor (D-Ï-A) chromophores, by reacting electron-rich alkynes with tetracyanoethylene. The desired tetracyanobutadiene-scaffolded peptides were obtained in good yields with various optical properties, λmax: 321-492 nm, ε: 21,000-65,000 molâ1 dm3 cmâ1 depending on the substitution pattern of the cyanobutadiene scaffold.
