Bottom-up synthesis of coordination polymers based on carborane backbones and Cu2(CO2)4 paddle-wheel: ligandmetathesis with metallotecons†
Abstract
Reported here are the bottom-up synthesis and structural analysis as well as the adsorption property investigation of a series of isostructural metal–organic frameworks based on carborane backbones and Cu2(CO2)4 units. All these compounds are 2D grid structures composed of four component rings. Using linear p-CDC (p-CDCH2 = 1,12-dihydroxycarbonyl-1,12-dicarba-closo-dodecaborane) as a backbone, only one type of ring formed. However, five types of rings may exist when m-CDCH2 (m-CDCH2 = 1,7-dihydroxycarbonyl-1,7-dicarba-closo-dodecaborane) was used due to its varied orientation. Here, the
