Mental Health.The tetrakisimidazolium salt H4-2(Br)4, featuring a central benzene linker and 1,2,4,5-(nBu-imidazolium-Ph-CH=CH-) substituents reacts with Ag2O in the presence of AgBF4 to yield the tetranuclear, oktakis-NHC assembly [3](BF4)4. Cation [3]4+ features four pairs of olefins from the two tetrakis-NHC ligands perfectly arranged for a subsequent [2+2] cycloaddition. Irradiation of [3](BF4)4 with a high pressure Hg lamp connects the two tetra-NHC ligands via four cyclobutane linkers to give compound [4](BF4)4. Removal of the templ
