Extensive spectral tuning of the proton transfer emission from green to red via a rational derivatization of salicylideneaniline

A series of salicylideneaniline derivatives 1a-lf were synthesized under mild condition in high yields, and characterized by ^1H NMR, HRMS, UV-vis and emission spectra. In solid and aprotic solvents 1a-1f exist mainly as E conformers that possess a sixmembered-ring hydrogen bond and undergo excited-...
