摘　　要： A Novel β-cyclodextrin dimer,2,2′-o-phenylenediseleno-bridgedbis（β-cyclodextrin）（2）,has been synthesized by reaction ofmono-[2-O-（p-tolylsulfonyl）]-β-cyclodextrin and poly（o-phenylenediselenide）.The complexation stability constants（Ks）and Gibbs free energy changes（-ΔG°）of dimer 2 with fourfluorescence dyes,that is,ammonium 8-anilino-1-naphthalene-sulfonate（ANS）,sodium 6-（p-toluidino）-2-naphthalenesul-fonate（TNS）,Acridine Red（AR）and Rhodamine B（RhB）have been determined in aqueous phosphate buffer solution(pH=7.2,0.1 mol·L-1at 25℃ by means of fluorescence spec-<正> A Novel β-cyclodextrin dimer,2,2′-o-phenylenediseleno-bridgedbis（β-cyclodextrin）（2）,has been synthesized by reaction ofmono-[2-O-（p-tolylsulfonyl）]-β-cyclodextrin and poly（o-phenylenediselenide）.The complexation stability constants（Ks）and Gibbs free energy changes（-ΔG°）of dimer 2 with fourfluorescence dyes,that is,ammonium 8-anilino-1-naphthalene-sulfonate（ANS）,sodium 6-（p-toluidino）-2-naphthalenesul-fonate（TNS）,Acridine Red（AR）and Rhodamine B（RhB）have been determined in aqueous phosphate buffer solution(pH=7.2,0.1 mol·L-1at 25℃ by means of fluorescence spec-
