微波合成及共價有機結構的提純

The chemistry of Covalent Organic Frameworks （COFs） is interesting yet underdeveloped. Typically COFs consist of low molecular weight elements such as boron, nitrogen, carbon, and oxygen, which form strong, covalent bonds similar to those in graphite and diamond. This networking imparts unique characteristics, among them high thermal stability sometimes up to 600 oC. Unlike hydrocarbon organic frameworks, heteroatomic frameworks have greater flexibility in their uses because they can be functionalized for gas storage devices, as photonics, and as catalysts. Original work conducted by Professor Omar Yaghi and co-workers details the synthesis of crystalline COFs consisting of carbon, boron, and oxygen, as shown in Scheme 1. Dehydration of diboronic acid （BDBA） and hexahydroxy triphenylene （HHTP） in mesitylene/dioxane at 120 oC for 72 h furnished COF-51, while self-condensation of tetra（4-dihydroxyborylphenyl）methane （TBPM） and its silane derivative TBPS by heating in mesitylene/dioxane at 85 oC for 96 h produced COF-102.2
