Description
Summary:By using 1-methyl-4-(carbomethoxy)pyridinium (MCMP + ) as counterions, two iodoargentate hybrids, 1D [MCMP][AgI 2 ] ( 1 ) and 3D [MCMP][Ag 3 I 4 ] ( 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-H O hydrogen bonded trimer in 1 and π-π/C-H π chain in 2 ). Two MCMP + /iodoargentate hybrids have been synthesized and they exhibit rare electron transfer photochromsim with a fast response rate, a wide response range and a long-lived charge-separated state, which is largely ascribed to the flexible aggregation of electron-deficient MCMP + counterions.
