根据动态猝灭原理，设计了一种新型的Cu2+开关荧光化学传感器，该传感器由对叔丁基硫代杯[芳烃(TCA)、十二烷基硫酸钠(SDS)和茂金属组成，在水溶液中自组装而成。由于胶束内络合物-荧光团的电子传递或三氯乙酸与Cu2+离子络合所产生的能量传递效应，Cu2+离子的加入会导致胶束内茂金属离子的荧光发射猝灭。实验结果表明：在三氯乙酸/茂金属的摩尔比为800/1，十二烷基硫酸钠浓度为150 mmol/L，pH值大于9的条件下，根据荧光猝灭，可以在一定范围内线性测定铜离子的浓度。
According to the principle of dynamic quenching a new ON-OFF fluorescent chemosensor for Cu2+ ions was designed, this chemosensor was composed of p-tert-butylthiacalix [arene (TCA),sodium dodecyl sulfate (SDS) and perylene through the form of self-assembly in aqueous solution. Addition of Cu2+ ions could result in a quenching of the fluorescence emission of perylene inside micelles, which due to intramicellar complex-fluorophore electron-transfer or energy-transfer effects induced by the complexation of TCA with the Cu2+ ions.The experimental results indicated that: Under the condition of TCA/perylene was 800/1, SDS concentration was 150mmol/L and pH value above 9, according to the fluorescence quenching ,within a certain range of the concentration of Cu2+ ion can be linearly determined.
