Charge-Transfer Chromophores

The reaction of a variety of N,N-dialkylamino (DAA)-substituted alkynes and tetracyanoethylene (TCNE) and tetracyanoquinodimethane (TCNQ) give a new class of donor-acceptor (D-A) chromophores by [2 + 2] cycloadditions, which exhibit exceptionally strong charge-transfer interactions. In this project, we focus on various powerful donor-substituted alkynes instead of DAAs to both achieve charge-separated form and expand our synthetic methodology as atom-economic reactions
