摘要

Abstract A bis (Zn II–porphyrin) tweezer host with anthracene components as apex and side- arms has been synthesized. Mono-(pyridine) and bidentate (4, 4′-bipyridine) guests were used as models for single and double axial coordination inside the cavity, respectively. A series of dipyridylporphyrin guests with different substitution patterns and excited-state energy levels have association constants with the tweezers that are of the order of 10 6 M ...
