title: Stoichiometry-controlled structural and functional variation in two photochromic iodoargentates with a fast and wide range response.
abstract: By using 1-methyl-4-(carbomethoxy)pyridinium (MCMP+) as counterions, two iodoargentate hybrids, 1D [MCMP][AgI2] (1) and 3D [MCMP][Ag3I4] (2) have been synthesized and they exhibit rare electron transfer photochromism with a fast response rate, a wide response range and a long-lived charge-separated state in iodometallate systems. Noteworthily, the marked differences in the structure and photochromic performance of 1 and 2 are largely ascribed to the different aggregating behavior of electron-deficient MCMP+counterions (C-HO hydrogen bonded trimer in 1 and π-π/C-Hπ chain in 2).
