Spectroscopic Regulation Of Protonated Phthalocyanine Ruthenium Complexes

With the development of photoelectric technology,phthalocyanine has been widely applied in the field of LB film,optical storage medium,energy conversion materials,semiconductors,and etc.,In this paper,we synthesized a protonated phthalocyanine iridium complex(IrPcHCl2),focusing on a series of factors to control the absorption spectrum and its mechanism for further study.The main contents include the following three aspects.1.Spectral Regulation of IrPcHCl2 by solvent and concentrationThe iridium complexes with phthalocyanine as the ligand were designed and synthesized.The structures of IrPcHCl2 were characterized by 1H NMR,and high resolution mass spectrometry.The absorption spectra in CH2Cl2,CHCl3,THF,DMSO,DMF,CH3 CN were tested.The results show that the symmetry of the protonated phthalocyanine ring changes,making the Q band of IrPcHCl2 split.IrPcHCl2 showed deprotonation in DMSO,DMF and CH3 CN.The effects of concentration on IrPcHCl2 spectra were studied.The concentration of IrPcHCl2 did not occur in the experimental concentration range.2.Spectral regulation of IrPcHCl2 by acidThe effects of CF3SO3 H and CF3CO2 H on the absorption spectra of IrPcHCl2 were studied in THF,CH2Cl2 and benzonitrile.The results show that the strength of the acid and the polarity of the solvent affect the protonation of IrPcHCl2,which can cause the change of the absorption spectrum.3.Spectral regulation of IrPcHCl2 by silver saltThe work in this section revolves around the spectral control of IrPcHCl2 in four solvents(AgBF4,CF3SO3 Ag,CH3COOAg,CF3COOAg)in two solvents.Due to the anion of the alkaline and coordination capacity of the differences caused by changes in the spectrum.However,other metal ions do not have a significant effect on their absorption spectra,so IrPcHCl2 can achieve high selectivity detection of silver ions.
