| Abstract |
Self-assembly of ZnX2 (X = Cl, Br, and I) with 2,3-bis(4’-nicotiamidephenoxy)naphthalene L as a hemi-circular bidentate ligand containing chromophore moiety yields a systematic 46-membered metallacyclodimeric unit, [ZnX2L]2. These basic skeletons constitute, via interdigitated π∙∙∙π interactions in a staggered fashion, a unique ensemble forming both channels and cages. This can then be employed as an unusual "small molecule-recognition within the channel and the cage" host-guest system. Specifically, the ensemble with channel and cage significantly stabilizes the CH2I2 molecules in the order [ZnI2L]2 > [ZnBr2L]2 > [ZnCl2L]2. These three complexes have significant halogen effects on the photoluminescence (PL), thermal properties, and host-guest inclusion. The unprecedented supra ensemble containing both channel and cage reversibly adsorbs/desorbs small solvent molecules. |
