Abstract: 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 Nand Bare incorporated into the nonpolar cavity of β-CDas the second guest and the third one.The extra space inside the cavity is further filled by Nand B, and β-CDmore effectively shields 1-BrN from quenchers in aqueous solution.Bcompletely hinders the formation of Nexcimer.The greater rigidity of the complex was achieved.Consequently, much more intense fluorescence of RTPappears in comparison with the ternary β-CD:1-BrN:Bor β-CD:1-BrN:Ncomplex.The limit of detection is 7.38×10-8mol/Lfor 1-BrNand 1.36×10-6 mol/L for N.
