Ten new steroidal molecular tweezers were efficiently synthesized via a method employing microwave irradiation by using chenodeoxycholic acid as spacer and Schiff base unit as arm through the condensation of amines and different aromatic aldehydes. Compared with a conventional method, the yields were increased from 30%~75% to 85%~94% and the reaction times were reduced from 300~480 min to 0.5~1.5 min. The structures of these novel molecular tweezers were characterized by 1H NMR, IR, ESI-MS techniques and elemental analysis. The recognition properties of these molecular tweezers for organic molecules were investigated by UV-vis spectra. The results indicated that this type of molecular tweezers has good binding properties for organic molecules.

Key words: chenodeoxycholic acid, molecular tweezers, microwave synthesis, molecular recognition
