Effects of intramolecular hydrogen bonding and sterically forced non-coplanarity on organic donor/acceptor two-photon-absorbing molecules

Two photon absorption (2PA) is of great interest across many disciplines and there has been a large effort to increase the two-photon cross section ( σ 2 ) via synthetic modification, especially by enhancing intramolecular charge-transfer (ICT). This work takes the previously studied (7-benzothiazol...
