摘　　要：报道了含甲基取代的cryptophanes合成方法,并用荧光光谱法研究了其对氯仿的识别性能。其中cryptophane-E-Me与氯仿有更强的络合作用,其络合常数为480.5 L·mol^(-1)。这种cryptophane-E-Me与氯仿间较强及稳定的络合作用提供了一种方便、环保的痕量氯仿检测方法。The synthesis of cryptophanes with methyl substitutions was described,and recognition properties for chloroform were investigated by fluorescence spectrometry.Cryptophane-E-Me was prior for chloroform capture with a binding constant of 480.5 L·mol^(-1),and the strong and stable complexation between chloroform and cryptophane-E-Me provided a convenient and enviromental friendly method for trace chloform detection.
