Synthesis of a dihydroquinoline based merocyanine as a 'naked eye' and 'fluorogenic' sensor for hydrazine hydrate in aqueous medium and hydrazine gas

1,2,2,4-Tetramethyldihydroquinoline (TMDQ) is formylated at the 6-position and the resulting quinoline aldehyde is condensed with 3-methyl-1-phenyl-1H- pyrazol-5(4H)-one to obtain a merocyanine 6-pyrazolinyl TMDQ. The merocyanine is a selective and sensitive sensor for hydrazine hydrate in aqueous ethanolic medium and also for hydrazine gas. The merocyanine detects hydrazine hydrate selectively in less than 5 s over other amines, anions, and metals. The detection can be done simply by the naked eye and quantification can be done by absorbance/fluorescence spectroscopy. Hydrazine hydrate as well as hydrazine gas can be detected by the TLC plate technique.

Synthesis of a dihydroquinoline based fluorescent cyanine for selective, naked eye, and turn off detection of Fe3+ ions

A cyanine dye was synthesized by condensing 6-formylated 1,2,2,4-tetramethyl-1,2-dihydroquinoline (TMDQ) and 1,7-dimethyl-2-phenylimidazo[1,2-a]pyridin-1-ium iodide. The probe was a selective sensor for ferric ions in aqueous ethanolic solution. The senso

Multiple fluorescence ΔcIE and ΔrGB codes for sensing volatile organic compounds with a wide range of responses

A highly luminescent compound, stilbene-2,4-dimethyl-6-(1,2,2,4- tetramethyl-1,2-dihydroquinolin-6-yl)-1,3,5-s-triazine (MQT), exhibits solvent polarity-induced emission enhancement. A fluorescent sensor array was fabricated with MQT and porous polymer substrates. The colorimetric changes of the array exposed to VOCs can be readily distinguished by the naked eye. Post-processing procedures proved the high selectivity of the array for VOCs. The Royal Society of Chemistry 2011.
