Abstract
- An M<superscript>4</superscript>L<subscript>4</subscript> type metal-organic cage (MOC-19) has been synthesized from the one-pot reaction of tri(pyridinylmethylene)phenylbenzeneamine (TPBA) with hydrated Zn(ClO<subscript>4</subscript>)<subscript>2</subscript> under mild conditions and characterized by single-crystal X-Ray diffraction. Iodine capture studies show that the porous crystals of MOC-19 exhibit a versatile behavior to accumulate iodine species not only in vapor (for I<subscript>2</subscript>) but also in solution (for I<subscript>2</subscript> and I<subscript>3</subscript><superscript>−</superscript>), and anion-exchange experiments indicate the capacity to extract IO<subscript>3</subscript><superscript>−</superscript> anions from aqueous solution. Enrichment of iodine species from KI/I<subscript>2</subscript> aqueous solution proceeds facilely, revealing a pseudo-second-order kinetics of I<subscript>3</subscript><superscript>−</superscript> adsorption. Furthermore, the electrical conductivity of MOC-19 single crystals could be significantly altered by I<subscript>2</subscript> inclusion. [ABSTRACT FROM AUTHOR]
