摘要: 研究了β-环糊精(β-CD)溶液中直链脂肪醇(A)诱导1-溴萘(1-BrN)的室温磷光光谱性质.结果表明,三元包络物中1-BrN分子的磷光起初随醇中碳原子数的增加而增强,正戊醇对磷光呈现最大的敏化作用,随后从正己醇至正辛醇,磷光强度逐渐下降.测定了包络物组成和稳定常数,发现1-BfN和A:β-CD包络物的结合强度是三元包络物磷光强弱的决定性因素,并从三元包络物可能的结构解释了醇分子大小对室温磷光的影响.

Abstract: Room-temperature phosphorescence of 1-bromonaphthalene (1-BrN) induced byaliphatic alcohols(A) was investigated in aqueous aerated g-cyclodextrin(P-CD) solution.Itfollows that 1-BrNphosphorescence intensity initially increases with the increasing numberof the carbon atoms in an alcohol.n-Pentanol exhibits the most pronounced phosphorescenceenhancement, and subsequently the phosphorescence intensity gradually decreases from n-hexanol to n-octanol.The stoichiometry and the equilibrium constants of a ternary complexwere determined.It has been found that the binding of 1-BrNto A : P-CDcomplex is a pre-dominant factor of phosphorescence enhancement.The effect of alcohols on RTPwas ex-plained on the basis of the molecular size.

Key words: 1-Bromonaphthalene, P-Cyclodextrin, Aliphatic alcohols, Inclusion comlplex, Room-temperature phosphorescence
