Abstract

Abstract : 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. Abstract : By using 1-methyl-4-(carbomethoxy)pyridinium (MCMP + ) as counterions, two iodoargentate hybrids, 1D [MCMP][AgI2 ] (1 ) and 3D [MCMP][Ag3 I4 ] (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 of1 and2 are largely ascribed to the different aggregating behavior of electron-deficient MCMP + counterions (C–H⋯O hydrogen bonded trimer in1 and π–π/C–H⋯π chain in2 ).
