【摘要】：金属酞菁是一类具有18个π电子的平面共轭大环分子,由于其在可见光区域具有强烈的吸收,被认定为是最有潜力的可见光催化剂,然而金属酞菁在水溶液中容易相互缔结形成二聚体,使其催化活性明显降低,限制了其在可见光催化领域的发展。随着多孔有机材料的迅猛发展,越来越多的多功能材料被合成出来并成功应用于相关领域。结合金属酞菁结构的多功能特性,我们制备了一种基于金属酞菁骨架的多孔有机材料,该材料同时拥有金属酞菁性质和多孔有机材料的优点。本文首先通过固相法合成四硝基金属酞菁(MPc(NO_2)_4(M=Co,Cu)),其次将MPc(NO_2)_4(M=Co,Cu)还原得到四氨基金属酞菁(MPc(NH_2)_4(M=Co,Cu)),最后将MPc(NH_2)_4(M=Co,Cu)与对苯二甲醛通过脱水缩合反应合成金属酞菁基共轭微孔聚合物(MPc-CMPs(M=Co,Cu))。其结构通过红外光谱、紫外-可见吸收光谱、X射线衍射光谱等得到表征。以有机染料罗丹明B(RhB)为目标降解物,过氧化氢为氧化剂,MPc-CMPs(M=Co,Cu)为可见光催化剂,考察了MPc-CMPs(M=Co,Cu)的可见光催化性能;并经过二次重复使用,探究了其循环使用性能。实验结果表明:MPc-CMPs(M=Co,Cu)具有很好的可见光催化性能;并且可重复使用。
[Abstract]:Metal phthalocyanines are a class of planar conjugated macrocyclic molecules with 18 蟺 electrons. Because of their strong absorption in the visible region, metal phthalocyanines are considered as the most promising visible light catalysts. However, metal phthalocyanines are easily formed into dimers in aqueous solution, which reduces their catalytic activity and limits their development in the field of visible light catalysis. With the rapid development of porous organic materials, more and more multifunctional materials have been synthesized and successfully applied in related fields. A porous organic material based on metal phthalocyanine framework was prepared based on the multifunctional properties of metal phthalocyanine structure. The material has the advantages of both metal phthalocyanine properties and porous organic materials. In this paper, tetranitro metal phthalocyanine (MPc (NO_2) _ 4 (),) _ 4 (MPc (NO_2) _ 4 (MPc (NH_2) _ 4 was synthesized by solid state reaction. Finally, MPc (NH_2) _ 4 (MGCO _ (Cu) was synthesized by dehydration condensation of MPc (NH_2) _ 4 with p-phenylaldehydes to synthesize the conjugated metal phthalocyanine). Polymer (MPc-CMPs (Muco CoCu). Its structure was characterized by IR, UV-Vis absorption spectra and X-ray diffraction spectra. The visible light catalytic properties of organic dye Rhodamine B (RhB), hydrogen peroxide as oxidant, and MPc-CMPs (MPc-CMPs) as visible light catalyst were investigated, and the recycling performance of MPc-CMPs was studied after secondary reuse. The experimental results show that MPc-CMPs (Mucco Cu) has good visible light catalytic performance and can be reused.
