摘　　要：Novel highly sensitive chiral organic field-effect transistors(COFET)were developed by directly assembling imidazolium3,5-dimethylphenylcabamoylated-β-cyclodextrin(lm^+-Ph-β-CD)and 3,5-dimethylphenylcarbamoylated-β-CD(Ph-β-CD)respectively onto the semiconductor layer as sensing units.The Im+-Ph-β-CD/COFET afforded better enantioselectivity and a lowest detection concentration of10^-18 L/mol as well as the potentiality in quantitative analysis of commercial medicines.Novel highly sensitive chiral organic field-effect transistors（COFET） were developed by directly assembling imidazolium3,5-dimethylphenylcabamoylated-β-cyclodextrin（lm+-Ph-β-CD）and 3,5-dimethylphenylcarbamoylated-β-CD（Ph-β-CD） respectively onto the semiconductor layer as sensing units.The Im+-Ph-β-CD/COFET afforded better enantioselectivity and a lowest detection concentration of10-18 L/mol as well as the potentiality in quantitative analysis of commercial medicines.
