A new class of N-H proton transfer molecules: wide tautomer emission tuning from 590 nm to 770 nm via a facile, single site amino derivatization in 10-aminobenzo[h]quinoline

Facile derivation of 10-aminobenzo[h]quinoline via replacing one of the N-H hydrogen atoms by various substituents generates a new series of excited-state intramolecular N-H proton-transfer molecules, for which the proton-transfer emission can be widely tuned from 590 nm to 770 nm simply by harnessi...

Description
Summary:Facile derivation of 10-aminobenzo[h]quinoline via replacing one of the N-H hydrogen atoms by various substituents generates a new series of excited-state intramolecular N-H proton-transfer molecules, for which the proton-transfer emission can be widely tuned from 590 nm to 770 nm simply by harnessing the electron-donating/withdrawing strength of the substituents.
