Solvent-Induced Single Crystal–Single Crystal Transformation of an Interpenetrated Three-Dimensional Copper Triazole Catalytic Framework

The 2-fold interpenetrated 3D framework 1 can be solvent-induced to noninterpenetrated framework 1′ in a reversible single crystal–single crystal transformation fashion. In addition, 1′ represents the first catalyst based on triazole to catalyze the aerobic homocoupling of various substituted arylboronic acids.具有二重互穿结构的三维骨架1可通过溶剂诱导作用，以可逆单晶-单晶转变的方式转化为非互穿型骨架1′。此外，骨架1′是首款基于三唑(triazole)的催化剂，可催化各类取代芳基硼酸的有氧均偶联反应。
