Conformational analysis of a fluorescent rotor, 6-(2,2-dicyanovinyl)-1-(2-hydroxyethyl)-1,2,3,4-tetrahydroquinoline
Abstract
Two stable conformations of a fluorescent rotor have been estimated by a variable temperature 1H NMR study, including NOE measurement. The height of energy barrier between them is also assessed and confirmed by MO calculation and X-ray crystal structure.
