摘要：
Thin films of two partially benzylated beta-CDs (beta-cyclodextrins) were used to functionalize ITO (indium tin oxide) and Si/SiO2 substrates which were deposited by spin coating technique, to fabricate respectively a diode device and an EIS (electrolyte-insulator-semiconductor) sensor. We have studied electrical properties of ITO/beta-CDs (BZ)(n=5,10/Al) diodes by means of current-voltage measurement and impedance spectroscopy. The application of these new modified beta-CD (Bz)(n=5,10) in the field of chemical sensors has been studied. Electrochemical capacitance measurements with EIS structures were made to test and calibrate physico-chemical sensors with regards to their sensitivity and selectivity. The sensing properties of these partial benzylated beta-CD films towards Pb2+ in aqueous solution for sensor application were tested. A significant effect of the average of benzylation degree on both electrical and sensing properties has been investigated. (C) 2006 Elsevier B.V. All rights reserved.
