【摘要】：隨著光電技術的興起,酞菁在LB膜、光學存儲介質(zhì)、能量轉換、光電導材料、半導體、電致變色、電致發(fā)光、非線性光學等諸多方面得到了廣泛應用。本文設計合成了一種質(zhì)子化酞菁銥配合物(IrPc HCl2),主要研究溶劑、濃度、酸及金屬離子等因素對吸收光譜的調(diào)控,并對其機理進行初步探討,具體內(nèi)容包括以下三個方面:1.溶劑及濃度對IrPcHCl2的光譜調(diào)控設計合成了以酞菁為配體的銥配合物,通過核磁共振氫譜和高分辨率質(zhì)譜表征了IrPcHCl2的結構,研究了在CH2Cl2,CHCl3,THF,DMSO,DMF,CH3CN等溶劑中的吸收光譜。結果表明,IrPcHCl2在CH2Cl2,CHCl3,THF中由于質(zhì)子化作用使得酞菁環(huán)的對稱性發(fā)生改變,從而導致其Q帶分裂。IrPcHCl2在DMSO,DMF,CH3CN中呈現(xiàn)去質(zhì)子化狀態(tài)。并研究了在這六種溶劑中濃度對IrPcHCl2光譜的影響,在實驗濃度范圍內(nèi),IrPcHCl2并未發(fā)生明顯的聚集。2.酸對IrPcHCl2的光譜調(diào)控在THF,CH2Cl2,苯甲腈中,分別研究了CF3SO3H和CF3CO2H對IrPcHCl2吸收光譜的調(diào)控。結果表明,酸的強度以及溶劑的極性會影響IrPcHCl2質(zhì)子化程度,從而能引起吸收光譜的改變。3.銀鹽對IrPcHCl2的光譜調(diào)控圍繞在兩種溶劑中四種銀鹽(AgBF4,CF3SO3Ag,CH3COOAg,CF3COOAg)對IrPcHCl2的光譜調(diào)控。由于陰離子的堿性和配位能力的差異從而引起了吸收光譜的改變。但是,其他金屬離子對其吸收光譜并不產(chǎn)生明顯的影響,因此IrPcHCl2可以實現(xiàn)對銀離子的高選擇性比色檢測。
[Abstract]:With the development of photoelectric technology, phthalocyanine has been widely used in LB films, optical storage media, energy conversion, photoconductive materials, semiconductors, electrochromic, electroluminescence, nonlinear optics and so on. In this paper, a proton iridium phthalocyanine complex (IrPc HCl2) was designed and synthesized. The absorption spectra were regulated by solvent, concentration, acid and metal ions, and its mechanism was preliminarily discussed, including the following three aspects: 1. The iridium complexes with phthalocyanine as ligand were designed and synthesized by the spectral regulation of solvent and concentration on IrPcHCl2. The structure of IrPcHCl2 was characterized by NMR and high resolution mass spectrometry. The results show that the symmetry of phthalocyanine ring changes due to the protonation of IrPcHCl2 in CH2Cl2CHCl3THF, which leads to the deprotonation of the Q-band splitting of IrPcHCl2 in DMSO-DMFU CH3CN. The influence of the concentration of the six solvents on the IrPcHCl2 spectra was also studied. The concentration of IrPcHCl2 did not show obvious aggregation in the range of experimental concentration. The spectral regulation of acid on IrPcHCl2 was studied in THF Ch _ 2Cl _ 2 and benzonitrile. The regulation of CF3SO3H and CF3CO2H on the absorption spectrum of IrPcHCl2 was studied. The results show that the intensity of the acid and the polarity of the solvent will affect the degree of IrPcHCl2 protonation, which can cause the change of absorption spectrum. The spectral regulation of silver salts on IrPcHCl2 is centered on the spectral regulation of IrPcHCl2 by four silver salts (AgBF4CF-3SO3AgCG-CH3COOAg). The absorption spectrum is changed due to the difference of anionic alkalinity and coordination ability. However, other metal ions have no obvious effect on the absorption spectra, so IrPcHCl2 can achieve high selectivity colorimetric detection of silver ions.
