作者汪鹏,陈之荣,李浩宏（2019）在《Tetrameric(Bi4I16)4- Iodobismuthate Templated by 1,ω-Bis（isoquinoline）alkane Cation: Structure,Photoluminescence and Enhanced Thermochromism》一文中研究指出：Using 1,1?-bis(isoquinoline)-1,4-phenyldimethylenyl(BIQPM2+) cation as template, a new tetrameric(Bi4 I16)4-iodobismuthate-containing hybrid with formula of(BIQPM)2(Bi4 I16)·H2 O(1), has been prepared under solvothermal conditions. The centrosymmetric Bi4-4 I16 tetraanion is constructed from four edge-shared slightly distorted BiI6 octahedrons. Due to the presence of larger conjugated system(isoquinoline ring), strong π···π stacking interactions can be observed. Besides, strong I···I interactions can be monitored and extends the 0-D Bi4 I4-16 cluster to a quasi-1-D chain. The smaller energy gap of 2.13 eV is led by these non-covalent interactions. Its infrared emission might be caused by strong charge transfer between anions and cations. Furthermore, the reversible thermochromic behavior with low chromotropic temperature of 80 ℃ can be observed, whose mechanism was discussed.

Abstract

Using 1,1?-bis(isoquinoline)-1,4-phenyldimethylenyl(BIQPM2+) cation as template, a new tetrameric(Bi4 I16)4-iodobismuthate-containing hybrid with formula of(BIQPM)2(Bi4 I16)·H2 O(1), has been prepared under solvothermal conditions. The centrosymmetric Bi4-4 I16 tetraanion is constructed from four edge-shared slightly distorted BiI6 octahedrons. Due to the presence of larger conjugated system(isoquinoline ring), strong π···π stacking interactions can be observed. Besides, strong I···I interactions can be monitored and extends the 0-D Bi4 I4-16 cluster to a quasi-1-D chain. The smaller energy gap of 2.13 eV is led by these non-covalent interactions. Its infrared emission might be caused by strong charge transfer between anions and cations.
