摘要

By employing diimine ligands coordinated dimetallic clips ([(bpy) ₂Pd₂(NO₃)₂](NO₃) ₂ or [(phen)₂Pd₂(NO₃) ₂](NO₃)₂, where bpy = 2,2′-bipyridine, phen = 1,10-phenanthroline) as the corner and anthracene-, naphthalene-, and benzene-based dipyrazolate dianions as the linker, a series of positively charged metallomacrocycles ([M₄L₂]⁴⁺ or [M ₈L₄]⁸⁺) have been synthesized through a directed self-assembly method in aqueous solution. Every macrocycle has a cavity to bind solvent molecules or anions. The structures were characterized by elemental analysis, ¹H and ¹³C NMR, electrospray ionization mass spectrometry, and single crystal X-ray diffraction analysis for compound 1 4PF₆ (1 = {[(bpy)Pd]₄L¹ ₂}⁴⁺), 3 4PF₆ ·8CH₃CN· H₂O (3 = {[(bpy)Pd]₄L²₂} ⁴⁺), and 7 4PF₆·6H₂O (7 = {[(bpy)Pd]₄L⁵₂}⁴⁺). The 1:1 host-guest complexation for anthracene-based dipyrazolate-bridged macrocycles with aromatic guests was investigated via UV-vis and fluorescent titration.
