中文摘要: |
目前,刺激响应性金属-有机骨架(MOFs)材料在应用研究中已取得很多进展。但在这些研究中,它们大多只能对单一的刺激进行响应,只具有单刺激响应性质。这在实际应用中具有一定的局限性,难以满足应用中的高需求。为追求更加优异、更具市场的刺激响应性材料,开发具有多刺激响应性的新型MOFs材料很有意义。萘二酰亚胺(NDI)类衍生物因其较大的共轭体系、良好的共平面性、较小的HOMO-LUMO能级差而在刺激响应性方面有着巨大的潜力。本论文以5-氨基四氮唑(5-atz)和1,4,5,8-萘二甲酸酐(NBD)为原料设计合成了NDI-ATZ(L),并用该有机物作主要配体、以甲酸(AC)和均苯三甲酸(TMA)为辅助配体,和Cd(NO3)2反应得到一种新的配合物(1)。以该有机物作配体和Cd(NO3)2反应得到另一种新的配合物(2)。并通过单晶X-射线衍射、粉末X-射线衍射(PXRD)、红外光谱(IR)、紫外-可见漫反射、热重分析(TGA)和示差扫描量热法(DSC)对两种配合物进行了表征和多刺激响应性质研究。经过实验发现两种配合物都具有良好的光致变色特性和胺致变色特性。 |
外文摘要: |
At present, a lot of progress has been made in the application research of stimulus responsive metal-organic frameworks (MOFs) materials. But in these studies, most of them can only respond to a single stimulus. This has some limitations in practical application, and it is difficult to meet the high demand in the application. In order to pursue more excellent stimulus responsive materials, it is of great significance to develop new MOFs materials with multi-stimuli response properties. Naphthalenediimide (NDI) derivatives have great potential in stimulus responsive materials due to their large conjugated system, good coplanarity and small HOMO-LUMO energy level difference. In this paper, NDI-ATZ (L) was synthesized with 5-amino-1H-tetrazol (5-atz) and 1,4,5,8-naphthalenetetracarboxylic dianhydride (NBD). And a new complex (1) was obtained by the reaction of NDI-ATZ as the main ligand, formic acid (AC) and trimesic acid (TMA) as the auxiliary ligand with Cd(NO3)2. Another new complex (2) was successfully constructed using NDI-ATZ with Cd(NO3)2. The two complexes were characterized by single crystal X-ray diffraction, powder X-ray diffraction (PXRD), infrared spectroscopy (IR), UV-vis diffuse reflection, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results show that both complexes have good photochromism and amine induced discoloration. |
