摘要：

A common ribbon-like structure was found in the crystals of triptycenequinones (TPQs), triptycene-TCNQs (TP-TCNQs) and their clathrates. The characteristic structure can be regarded as a supramolecular unit the formation of which is aided by weak intermolecular D-A interactions. This view is supported by the host-guest D-A interactions appeared in the crystals of the clathrates of 5,8-dimethyl-TPQ and 5,8-dimethoxy-TP-TCNQ. Intermolecular C-(HO)-O-... hydrogen bonds seem to be present in TPQ derivatives. (C) 2001 Elsevier Science Ltd. All rights reserved.
