摘要

The reaction between 1,3,5-benzenetribenzoic acid (H_3BTB) and In(NO_3)_3 hydrate in diethylformamide yielded a new In~(III)-metal-organic framework, [(CH_3CH_2)_2NH_2]_3[In_3(BTB)_4]?10DEF?14H_2O (I). The countercation and solvent-free doubly interpenetrated I potentially contains 71.0% of solvent accessible void. Although the framework of I was not stable enough to maintain its original structure when the solvent molecules were removed, the as-prepared I was found to be a very good sorbent for acridine orange hydrochloride, a large Reichardt's dye, and hydrophobic iodine molecule in solution. The as-prepared I exhibited increased uptake amount in the order of Reichardt's dye >acridine orange hydrochloride >iodine. The largest uptake of the bulky Reichardt's dye by I could be attributed to the optimized structural fitting of Reichardt's dye into the large threedimensional void space of I. The structure of Reichardt's dye-encapsulated I_RD was unambiguously revealed by X-ray crystallography for the first time.
