设计合成了两个含Au(I)的化合物1和2,利用核磁共振(NMR)、红外光谱(IR)、元素分析等对其结构进行了表征.通过对其在二甲亚砜(DMSO)/水体系或N,N-二甲基甲酰胺(DMF)/水体系中荧光光谱的研究,显示其在纯有机溶剂中没有荧光,而在混合体系中,水含量达到一定程度后,其荧光会显著增强.这表明化合物1和2均具有明显的聚集诱导发光性质.对化合物1和2的固体粉末进行研磨,其固体荧光会显著增强,而且将研磨后的样品暴露在有机溶剂蒸汽中一段时间后,荧光强度又会恢复到原来的强度.这表明化合物1和2均具有机械变色的性质.通过它们的X射线粉末衍射(XRD)测试发现,这两个化合物在研磨前后分子堆积态实现了从晶态到无定形态的转变.因此这两个化合物具有成为新型智能材料的潜质.
Two compounds 1 and 2 containing Au (I) were designed and synthesized, their structures were characterized by means of nuclear magnetic resonance (NMR), infrared spectroscopy (IR) and elemental analysis, / Water system or N, N-dimethylformamide (DMF) / water system fluorescence spectra showed no fluorescence in pure organic solvents, and in the mixed system, the water content reaches a certain level, its fluorescence This shows a significant aggregation-induced luminescence properties for both compounds 1 and 2. Grinding the solid powders of compounds 1 and 2 significantly increases the solid fluorescence and exposes the milled sample to a period of organic solvent vapor Fluorescence intensity returned to its original value after time, indicating that both compounds 1 and 2 have the property of mechanical discoloration and their X-ray powder diffraction (XRD) tests revealed that both compounds were achieved before and after milling From the crystalline state to amorphous state transition, so these two compounds have the potential to become a new type of smart materials.
