摘要：

Novel highly sensitive chiral organic field-effect transistors (COFET) were developed by directly assembling imidazolium3,5-dimethylphenylcabamoylated-beta-cyclodextrin(Im(+)-beta-CD)and 3,5-dimethylphenylcarbamoylated-beta-CD (Ph-beta-CD) respectively onto the semiconductor layer as sensing units. The Im(+)-Ph-beta-CD/COFET afforded better enantioselectivity and a lowest detection concentration of 10(-18) L/mol as well as the potentiality in quantitative analysis of commercial medicines.
