Zhang, Ya-Wen;Das, Rajorshi;Li, Yang;Wang, Yao-Yu;Han, Ying-Feng research published 《 Synthesis, Characterization, and Properties of Organometallic Molecular Cylinders Bearing Bulky Imidazo[1,5-a]pyridine-Based N-Heterocyclic Carbene Ligands》, the research content is summarized as follows. The metal-controlled self-assembly of organometallic mol. cylinders from a series of imidazo[1,5-a]pyridine-based tris-NHC ligands is described in this report. The imidazo[1,5-a]pyridinium salts H3-L(PF6)3 (L= 4a–4c) were treated with 1.5 equiv of Ag2O to yield the trinuclear AgI hexacarbene cages [Ag3(L)2](PF6)3 (L= 4a–4c), in which three AgI are sandwiched between the two tricarbene ligands. The silver(I) complexes [Ag3(L)2](PF6)3 underwent a facile transmetalation reaction in the presence of 3 equiv of [AuCl(tht)] (tht=tetrahydrothiophene) to furnish the trinuclear AuI cylinder-like cages [Au3(L)2](PF6)3 (L= 4a–4c) without destruction of the metallosupramol. structure. The new hexacarbene assemblies feature a large cavity that can easily accommodate a mol. of DMSO as mol. guest. This is the first study of a unique “host-guest” system containing an organometallic cylinder-like cage derived exclusively from poly-NHC ligands.
