A novel chiral sensor based on the self‐assembled monolayer of (6 A ‐ω‐mercaptoethylureado‐6 A ‐deoxy)heptakis(2,3‐di‐ o ‐phenylcarbamoyl)‐6 B , 6 C , 6 D , 6 E , 6 F , 6 G ‐ hexa‐ o ‐phenylcarbamoyl‐β‐cyclodextrin (Ph‐β‐CD‐SH) on a quartz crystal transducer for chiral recognition was set up. ( R,S )‐(±)‐(3‐Methoxyphenyl)ethylamine were recognized by this QCM chiral sensor with a QCM chiral discrimination factor of 1.33. Furthermore, UV spectroscopy was used to investigate the mechanism of host‐guest interactions between (6 A ‐azido‐6 A ‐deoxy)heptakis(2,3‐di‐ o ‐phenylcarbamoyl)‐6 B , 6 C , 6 D , 6 E , 6 F , 6 G ‐hexa‐ o ‐phenylcarbamoyl‐β‐cyclodextrin (Ph‐β‐CD) and ( R,S )‐(±)‐(3‐methoxyphenyl) ethylamine. The UV discrimination factor was determined to be 0.066. Chirality, 2010. © 2009 Wiley‐Liss, Inc.
