Synthesis, solution and solid-state fluorescence of 2-diethylaminocinchomeronic dinitrile derivatives?
RSC Advances Pub Date: 2017-07-12 DOI: 10.1039/C7RA06217F
Abstract
A facile approach to the synthesis of novel 2-diethylaminocinchomeronic dinitriles, which are found to be fluorescent both in the solution and in a solid states, was developed. Absorption, fluorescence and solvatochromic properties as well as a crystal structure of the synthesized compounds were investigated. It was found that the 2-diethylaminocinchomeronic dinitrile derivatives with methoxy groups in the aryl moiety possess the most intensive emission in nonpolar solvents with fluorescence quantum yields up to 0.59.
