The halogenated hydrocarbon and pyridine are used in the synthesis of room temperature ionic liquid intermediates bromided N-propyl pyridine PPB, and the nuclear magnetic resonance instrument and the intermediate infrared spectrometer are used in chemical structure characterization, so it is determined that the synthesis is the room temperature ionic intermediates PPB. We use differential scanning calorimetric method for the determination of PPB melting point and enthalpy change. We use the double decomposition reaction of PPB and NaBF4in acetone for the synthesis of PP-BF4ionic liquids. We use infrared spectrometer for the structure characterization, it is proved that we have gotten PP-BF4room temperature ionic liquids. Solvent polarity and acid alkali both will have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid, so in the research of ultraviolet spectrum diagram of ionic liquids and other solvent mixed solution, it is necessary to indicate which solvent is used.

The halogenated hydrocarbon and pyridine are used in the synthesis of room temperature ionic liquid intermediates bromided N-heptyl pyridine HEPB, and the nuclear magnetic resonance instrument and the intermediate infrared spectrometer are used in chemical structure characterization, so it is determined that the synthesis is the room temperature ionic intermediates HEPB. We use differential scanning calorimetric method for the determination of HEPB melting point and enthalpy change. We use the double decomposition reaction of HEPB and NaBF4in acetone for the synthesis of HEP-BF4ionic liquids. We use infrared spectrometer for the structure characterization, it is proved that we have gotten HEP-BF4room temperature ionic liquids. Solvent polarity and acid alkali both will have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid, so in the research of ultraviolet spectrum diagram of ionic liquids and other solvent mixed solution, it is necessary to indicate which solvent is used.

Ionic liquids combine a set of proper ties like non-flammability, non-volatility, high ionic density and intrinsically high ionic conductivity; they also behave as good solvents for various chemical and electrochemical processes. These attributes make them appealing as alternative materials to replace conventional solvents, wherefore the interest in ionic liquid based materials for diverse electrochemical devices has boosted in the last few decades. The halogenated hydrocarbon and pyridine are used in the preparation of room temperature ionic liquid intermediates bromided N-octyl pyridine OPB, and the intermediate infrared spectrometer are used in chemical structure characterization, so it is determined that the product is the room temperature ionic intermediates OPB. Infrared spectrometer for the structure characterization is used, it is proved that OP-BF4 room temperature ionic liquid has been gotten. Both solvent polarity and acid alkali have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid. If the ultraviolet spectrum diagram of ionic liquids and other solvent mixed solution is studied, it is necessary to indicate which solvent is used.

The halogenated hydrocarbon and pyridine are used in the synthesis of room temperature ionic liquid intermediates chlorinated N-butyl pyridine BPC. We use the double decomposition reaction of BPC and NaNO3in acetone for the synthesis of BP-NO3 ionic liquids. We use infrared spectrometer for the structSubscript texture characterization, it is proved that we have gotten BP-NO3room temperature ionic liquids. Solvent polarity and acidSubscript textalkali both will have a room temperature ionic liquid ultraviolet spectrum diagram happen displacement, so in the ionic liquid and other solvent mixed solution of ultraviolet spectrum diagram, want to indicate the use of solvent. Therefore, solvent polarity and acid alkali both will have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid.

Unlike most other electron donor–acceptor (EDA) molecules, aminochalcones exhibit unusual solvent polarity-dependent fluorescence behavior. The photophysical behavior of two aminochalcones, namely, 4-aminochalcone (AC) and 4-dimethylaminochalcone (DMAC), has been studied in a viscous room-temperature ionic liquid (IL), 1-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF6], by steady-state and time-resolved fluorescence techniques. The observation of a single emission band in viscous IL, which is similar to the one observed in less viscous polar conventional solvents, suggests no twisting is necessary for the formation of the charge-transfer state from which the emission of aminochalcones originates. The fluorescence decay profiles, solvation dynamics, and excitation-wavelength-dependent emission behavior of AC are found to be quite different from those of DMAC in the IL. The observed difference is attributed to specific H-bonding interaction between AC and [bmim][PF6].
