Room-temperature phosphorescence of 6-bromo-2-naphthol included by α-cyclodextrin in aqueous solution
Abstract
In aerated aqueous solutions, room-temperature phosphorescence of 6-bromo-2-naphthol is observed with an inclusion complex composed of one 6-bromo-2-naphthol (BN) and two α-cyclodextrin (α-CD) molecules, whereas a 1 : 1 α-CD–BN inclusion complex does not phosphoresce at room temperature.
