DESCRIPTION:Traditional applications of metal-organic frameworks (MOFs) ar
 e focused on gas storage and separation\, which take advantage of the inhe
 rent porosity and high surface area of these materials. The MOFs’ use in
  technologies that require charge transport have lagged behind\, however\,
  because MOFs are poor conductors of electricity. We show that design prin
 ciples honed from decades of previous research in molecular conductors can
  be employed to produce MOFs with remarkable charge mobility and conductiv
 ity values that rival or surpass those of common organic semiconductors an
 d even graphite. We further show that these\, ordered\, and crystalline co
 nductors can be used for a variety of applications in energy storage\, ele
 ctrocatalysis\, electrochromics\, and selective chemiresistive sensing. An
 other virtually untapped area of MOF chemistry is related to their potenti
 al to mediate redox reactivity and heterogeneous catalysis through their m
 etal nodes. We show that MOFs can be thought of as unique macromolecular l
 igands that give rise to unusual molecular clusters where small molecules 
 can react in a matrix-like environment\, akin to the metal binding pockets
  of metalloproteins. By employing a mild\, highly modular synthetic method
  and a suite of spectroscopic techniques\, we show that redox reactivity a
 t MOF nodes can lead to the isolation and characterization of highly unsta
 ble intermediates relevant to biological and industrial catalysis\, and to
  industrially relevant catalytic transformations that are currently perfor
 med only by homogeneous catalysts.
