The luminescence thermochromism properties of two entangled copper(I)-iodide coordination polymers formulated [Cu4I4(dmimpr)2]n (1) and [Cu6I6(dimb)3]n (2) (dmimpr = 1,3-di(2-methyl-imidazol-1-yl)propane, dimb = 1,4-di(imidazol-1-yl)butane) are reported. Upon cooling by liquid nitrogen, their solid-state luminescences at room temperature are drastically changed with the large red-shifts of 41 and 78 nm for 1 and 2, respectively. The correlation between luminescence thermochromism and temperature-dependent variation of the Cu···Cu distance is also elucidated.
本文报道了两个纠缠的铜（I）-碘配位聚合物[Cu4I4(dmimpr)2]n（1）和[Cu6I6(dimb)3]n（2）（dmimpr=1,3-二（2-甲基-咪唑-1-基）丙烷，dimb=1,4-二（咪唑-1-基）丁烷）的发光热致变色性质。在通过液氮冷却时，它们在室温下的固态发光强度发生了剧烈变化，1 和 2 的红移分别为 41nm 和 78nm。还阐明了发光热致变色与 Cu···Cu 距离随温度变化的相关性。
