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. |
