Novel highly sensitive chiral organic field-effect transistors (COFET) were developed by directly assembling imidazolium3,5-dimethylphenylcabamoylated-β-cyclodextrin(Im+-Ph-β-CD)and 3,5-dime-thylphenylcarbamoylated-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 of 10-18 L/mol as well as the potentiality in quantitative analysis of commercial medicines.
