Abstract
Synthesis of glycidyl ethers of quercetin and studies of their structure and spectral properties have been carried out. Using FTIR spectroscopy, 1H and HSQC NMR spectroscopy, mass spectrometry and quantum chemical simulations, it was shown that glycidation of 7-hydroxy and 4′-hydroxy groups primarily takes place, and then, the sequential glycidation of 3′-hydroxy and, further, 3-hydroxy groups occurs. Solvatochromic effects and quadratic polarizability of the obtained ethers—7,4′-diglycidyloxy-3,5,3′-trihydroxyflavone, 7,3′,4′-triglycidyloxy-5,3′-dihydroxyflavone and 3,7,3′,4′-tetraglycidyloxy-5-hydroxyflavone—were studied. It was shown that the diglycidyl and triglycidyl ethers can be used for creation of new polymeric NLO materials.
