摘　　要：双异喹啉阳离子导向的无机-有机杂化材料因其优良的光学性能,一直是化学、材料等相关领域的研究热点.而单壁碳纳米管(SWCNT)以其特有的单层碳原子结构以及电子传递性能,也受到了人们越来越多的关注.近年来,这2种材料在非线性光学(光限幅)方面的报道都呈现上升的趋势.双异喹啉阳离子导向的无机-有机杂化材料虽然有优异的光限幅性能,但是由于双异喹啉在溶液中的浓度较高时很容易发生聚集,产生堆积,从而影响材料的光限幅性能.单纯的SWCNT其溶解性较差,在溶剂中难以加工操作,制约了它在光限幅领域的实际应用.本文尝试采用共价连接的方式,将这2种材料结合到一起,以期得到一种拥有良好非线性光学性能的新材料.本文采用自由基亲电加成反应,得到苯酚共价功能化的SWCNT,之后采用功能化的SWCNT与双异喹啉及其配合物反应,合成了3个双异喹啉及其配合物修饰的SWCNT纳米杂化材料(SWCNT-TPPH 66,SWCNT-TPPZn 77和SWCNT-TPPCd 88).分别用红外光谱、紫外光谱、荧光光谱、热重分析、X射线衍射(XRD)和拉曼光谱对其进行了表征,证实了双异喹啉及其配合物与SWCNT的共价连接,为以后合成该种材料提供了一种合成路径.Bisisoquinoline cation-oriented inorganic-organic hybrid materials have been the focus of chemistry,materials and other related fields because of their excellent optical properties.Single-walled carbon nanotubes(SWNTS)have attracted more and more attention due to their unique single-layer carbon structure and electron transport properties.In recent years,the reports on nonlinear optics(optical limiting)of these two materials are increasing.Although bisisoquinoline cation-oriented inorganic-organic hybrid materials have excellent optical limiting performance,due to the high concentration of diisoquinoline in solution,it is easy to accumulate and produce accumulation,thus affecting the optical limiting performance of the materials.Simple single-walled carbon nanotubes have poor solubility and are difficult to be processed in solvents,which restricts their practical application in the field of optical limiting.We have tried to combine these two materials together by means of covalent connection,in order to obtain a new material with good nonlinear optical properties.Phenol covalently functionalized SWCNT were obtained by radical electrophilic addition reaction,and then functionalized SWCNT was used to react with diisoquinoline and its complexes.Swcnt-tpph 66,SWCNT-TPPZn 77 and SWCNT-TPPCD 88 were modified with three bisisoquinoline and their complexes.They were characterized by infrared,ultraviolet,fluorescence,thermogravimetry,X-Ray Diffraction and Raman spectroscopy,respectively.The covalent bonding of bisisoquinoline and its complex with single-wall carbon nanotubes was confirmed,which provides a synthesis path for the future synthesis of this kind of material.
