摘要: Abstract In this work we studied the photoluminescence (PL) behaviour of a new intramolecular charge transfer (ICT) compound, DHAIA. It shows ICT solvent effect in common organic solvents and specific aqueous medium as confirmed by its spectra characterization. The can be ascribed to transition from charge-transfer (CT) state locally excited (LE) state, which is activated intermolecular hydrogen bonding. proposed mechanism was DFT calculations. compound serve reliable sensor for identifying brand liquors confirming their authenticity, based on such unique intrinsic fluorogen. aimed fingerprint different via plotting characteristic factors recorded spectroscopic analysis. succeeded an adulterated liquor sample, once commercially available, provided Municipal Public Security Bureau, showing great potential differentiation identification.
