The compound about proton transfer has been widely studied,especially 2-substituted benzothiazole and benzimidazole having excited proton transfer process.This chemical compounds are relatively sensitive to solvents and can effectively or specifically identify certain ions.BODIPY compounds have strong fluorescence properties and have been widely used in fields such as fluorescent probes and optical switches.The complementarity of multiple models at the molecular level has become a current development trend to further develop new functional materials.This dissertation analyzes the structure and possible derivation of BODIPY model compounds(F1)from two aspects of theory and experiment,and then synthesizes both type of dyad compound having strong fluorescence that is TY1 and IY1 respectively.By measuring the fluorescence spectrum of binary compounds at different solvents or different cations of the certain solvent or the same cations of different concentration in the certain solvent,the effects of solvents and ions on the spectra were studied.1.Two compounds,namely T1 and F1,were synthesized by a simple and efficient method,and were characterized by nuclear magnetic resonance spectroscopy,high resolution mass spectrometry and melting point.single crystal of these two compounds was cultivated,of which the crystal structure was determined and analyzed.By comparing the crystal structure parameters with the results of density functional calculations,possible derivatives of T1 and F1 were studied.By measuring the UV-Vis absorption spectra of T1 in different solvents,the effects of solvents on T1 UV-Vis absorption spectra were studied.By measuring the UV-Vis absorption and fluorescence spectra of F1 in different solvents,the influence of the solvent on the two spectra of F1 was studied.2.A binary compound,TY1,was synthesized in a bidirectional and simultaneous manner and characterized by nuclear magnetic resonance spectroscopy and mass spectrometry.By measuring the UV-Vis and fluorescence spectra of TY1 in different solvents,the effects of solvents on the two spectrums were studied.By measuring the effect of different cations on TY1 fluorescence spectra in dimethyl sulfoxide,the phenomenon that TY1 specifically recognizes divalent nickel ions and divalent copper ions was studied.By measuring the fluorescence spectra of TY1 at different concentrations of the same ions in dimethyl sulfoxide,the linear relationship between the fluorescence intensity of TY1 and the square root of the concentration of divalent nickel ions or divalent copper ions was studied.By theoretically calculating the structure of TY1,the prospect of its use as an electroluminescent material is studied.3.A two-component compound,IY1,was synthesized in a two-way simultaneous manner and characterized by nuclear magnetic resonance spectroscopy and mass spectrometry.By measuring the UV-Vis and fluorescence spectra of IY1 in different solvents,the effects of solvents on the two spectra were studied.By measuring the effect of different cations on the fluorescence spectrum of IY1 in dimethyl sulfoxide,the phenomenon that IY1 specifically recognizes divalent nickel ions and divalent copper ions was studied.By measuring the fluorescence spectra of IY1 at different concentrations of the same ions in dimethyl sulfoxide,the linear relationship between the fluorescence intensity of IY1 and the concentration of divalent nickel ions or divalent copper ions was studied.By theoretically calculating the structure of IY1,the prospect of its use as an electroluminescent material is studied.
