Abstract: | Supramolecular coordination‐driven self‐assembly rectangle 1a have be formation of distorted shapes, with a strong π···π interactions between the L1 and anthracene in 1b ( 1a ? anthracene) that changed the size to desired and supported by single‐crystal Xray diffraction data. The formation of 1c( 1a ? DMF) has been further corroborated by the single‐crystal and 1b also can reaction with decaborane to form ortho‐carborane complex 1d . A self‐assembled triangular prism cage 2a consisting of binuclear half‐sandwich metal precursors [Cp*2Rh2(μ‐BiBzIm)]Cl2 (BiBzIm = 2,2′‐bisbenzimidazole) ligands and L2 were found to capsulated a triphenylene in cage. Another two kinds of prismatic cages ( 3a and 3b ) were obtained from the reactions of the bis‐chelating‐coordinated [Cp*2Rh2(μ‐CA)]Cl2(CA = chloranilate) with L2 and L3 in the presence of AgOTf (OTf = CF3SO3) in CH3OH, and cage 3b have a perfect sized cavity to self‐assembled with anthracene in it. |
