A new silver(I) iodide cluster [AgI(TMP)] (TMP = tris(3-methylphenyl)-phosphine) 1 shows triply stimuli-responsive luminescent chromism, namely, mechano-, thermo- and solvent-responsive chromism, which is isostructural to our previously reported [CuI(TMP)] 2 but shows quite different luminescence in response to the external stimuli. Especially, during the mechanical grinding, the relative intensities of HE and LE of 1 varied with a concomitant hypsochromic shift, and when the temperature was decreased from 300 to 5 K, unprecedented contrary thermo-responsive trend for single crystal and powered samples (blueshift of single crystals and redshift of powdered samples) was observed. These distinct characters of 1 should be due to the different molecular packing modes, metallic interactions and the unique character of Ag(I) ion.
一种新型碘化银（I）簇合物[AgI(TMP)]（TMP = 三（3-甲基苯基）膦）1表现出三重刺激响应发光变色现象，即机械、热和溶剂响应变色，它与我们之前报道的[CuI(TMP)] 2同构，但在外部刺激下表现出截然不同的发光。特别是，在机械研磨过程中，1的高能发射（HE）和低能发射（LE）的相对强度随同时发生的蓝移而变化，并且当温度从300 K降至5 K时，观察到单晶和粉末样品出现前所未有的相反热响应趋势（单晶蓝移，粉末样品红移）。1的这些独特特性应归因于不同的分子堆积模式、金属相互作用以及Ag（I）离子的独特性质。
