Introduction of an electron push-pull system yields a planar Red Kaede fluorescence protein chromophore analogue stabilized by a C = O…π interaction / created by Ashish Singh, Basanta Kumar Rajbongshi and Gurunath Ramanathan - Journal of chemical sciences Volume 127, number 5, .
Crystal structures of four red kaede fluorescence protein chromophore analogues are reported here. Molecules I-III adopt a non-planar geometry stabilized by π…π stacking and hydrogen bonding. Introduction of an electron push-pull system induces molecule IV to be planar and a C = O…π supramolecular interaction is observed as well. Strong electron withdrawing and donating groups also ensure formation of a higher order two and three dimensional supramolecular architecture through hydrogen bonds in molecules I and IV. All the analogues exhibit good photoluminescence properties and emit in the red region with excellent quantum yields.
