摘要 萘和正丁醇存在下β-环糊精诱导1-溴萘室温磷光的研究杜新贞,张勇,黄贤智,李耀群,江云宝,陈国珍(厦门大学化学系、环境科学研究中心,厦门,361005)关键词1-溴萘,β-环糊精,萘,室温磷光室温下β-环糊精(β-CD)诱导的发光现象由于其不同于胶束... Intense room temperature phosphorescence(RTP)from host-guest inclusion complex of β-cyclodextrin(β-CD)with 1-bromonaphthalene(1-BrN),stabilized by naphthalene (N)and 1-butanol(B), has been investigated, It has been confirmed that N and B are incorporated into the nonpolar cavity of β-CD as the second guest and the third one. The extra space inside the cavity is further filled by N and B, and β-CD more effectively shields 1-BrN from quenchers in aqueous solution.B completely hinders the formation of N excimer.The greater rigidity of the complex was achieved. Consequently, much more intense fluorescence of RTP appears in comparison with the ternary β-CD:1-BrN:B or β-CD:1-BrN:N complex.The limit of detection is 7. 38×10 ̄(-8)mol/L for 1-BrN and 1.36×10 ̄(-6) mol/L for N.
