An oxamide-functionalized ternary indium-organic framework.

Solvothermal reaction between oxamide-functionalized semi-rigid tetracarboxylate linker and indium metal ion affords a rare ternary AFMOF, which remarkably displays two distinct SBUs, leading to an unprecedented (3,3,4,4,4)-c network. Solvothermal one-pot reaction between indium nitrate and an oxamide-functionalized tetracarboxylate linker affords a rare ternary MOF, which exhibits two distinct SBUs based on sole metal ions and pure homo-functional ligands, in contrast to other multicomponent MOFs constructed from either mixed-metals with hetero-functional linker or mixed-linkers with sole metal. The MOF also demonstrates relatively efficient adsorption capability toward MB and tunable blue-to-green photoluminescence upon variation of excitation wavelengths. [ABSTRACT FROM AUTHOR]
