The measurement of the polarization ratio (PR) of guest transitions in mixed molecular crystals has been used as a tool to study the effect of host-guest interaction. Two mixed crystnl systems, namely naphthacene in transstllbene and anthracene in carbazole, have been studied. In the former system,

## Abstract A chiral molecular tweezer obtained from (+)βusnic acid placed in solution in the presence of various aromatic compounds afforded complexes with low association constants. Thus, the Xβray structure of assembly **3i** is presented, where the guest is sandwiched between the two pincers of
