摘要

Two new “Y” type triaryl amino chromophores with tricyanovinyldihydrofuran groups as electronic acceptor are synthesized and found to exhibit blue-shifted absorption in comparison with the corresponding D–π–A analogues while demonstrating significantly enhanced optical nonlinearity, as well as good thermal stability.
