Excimer Emission Based on β-cyclodextrin Inclusion Complex
摘要
Abstract
The excimer emission has been widely used in sensing,detection,imaging and illumination because of its broad emission bandwidth and large Stokes shift.In this work,a new strategy based on the formation of inclusion complexes with β-CD was proposed for the construction of excimer emission luminophores.Two Schiff bases were synthesized by conjugat-ing anthraldehyde/pyrenealdehyde with 1-amantadine.Both of them showed excimer-enhanced aggregaton emissiom.The adamantyl group of Schiff base perfectly matched with the hydrophobic cavity of β-CD,and the emission properties of Schiff base obviously changed after forming the inclusion complex with β-CD.In H2O,the emission of ANAD was depen-dent on the concentrations of β-CD.The excimer emission was observed only when c(ANAD)∶c(β-CD)was 1∶2.Being different from ANAD,PYAD always showed the excimer emission under any circumstances,but the emission intensity was weakened by the excess β-CD.ANAD and PYAD in solid state exhibited non-fluorescence.When included by β-CD,both of them exhibited intense excimer emission.In short,the formation of inclusion complex with β-CD was favorable to ex-cimer emission.关键词
