Abstract
Room-temperature phosphorescence of 1-bromonaphthalene (1-BrN) induced by aliphatic alcohols(A) was investigated in aqueous aerated beta-cyclodextrin (beta-CD) solution. It follows that 1-BrN phosphorescence intensity initially increases with the increasing number of the carbon atoms in an alcohol. n-Pentanol exhibits the most pronounced phosphorescence enhancement, and subsequently the phosphorescence intensity gradually decreases from n-hexanol to n-octanol. The stoichiometry and the equilibrium constants of a ternary complex were determined. It has been found that the binding of 1-BrN to A : beta-CD complex is a predominant factor of phosphorescence enhancement. The effect of alcohols on RTP was explained on the basis of the molecular size.
