Quaterthiophenes bearing one (1) or two (2) alkanethiol chains attached at the internal β-position of the outermost thiophene ring through a sulfide linkage have been synthesized. Cyclic voltammetric analysis of their electrochemical behavior in solution suggests that electrooxidation of the doubly substituted oligomer 2 leads to electrodeposition of a poly(disulfide) on the anode surface. Monolayers of 1 or 2 on gold surfaces have been investigated and characterized by cyclic voltammetry, ellipsometry, contact angle measurement, and X-ray photoelectron spectroscopy. The results of these investigations indicate that introduction of two thiol groups in the structure leads to double fixation of the oligothiophene chain with the main axis of the conjugated system oriented parallel to the surface. The effects of single versus double fixation of the quaterthiophene chain on the electrochemical properties and stability of the corresponding monolayers are discussed.

Halogenated-1-(4-sulfydryl butyl)-3-methylimidazole ionic liquid, and preparation method and application thereof
-
Paragraph 0052, (2017/04/27)
The invention discloses halogenated-1-(4-sulfydryl butyl)-3-methylimidazole ionic liquid, and a preparation method and application thereof. The ionic liquid has a structural formula shown as the formula I. According to the halogenated-1-(4-sulfydryl butyl)-3-methylimidazole ionic liquid, sulfydryl butyl is used as a substituent group; lone pair electrons of sulfydryl can generate p-Pi conjugation with large Pi bonds on an imidazole ring; the distance from the sulfydryl to the imidazole ring is proper through the butyl; the conditions of repulsion force increase when the distance is too small and sulfydryl coating when the distance is too great are avoided; the microenvironment effect of the ionic liquid is combined, so that the fluorescence property of the ionic liquid can reach the optimum. The ionic liquid can be applied to an ionic liquid microextraction system, is used as an extracting agent or a dispersing agent, and is suitable for being popularized and applied to an organic solvent-free microextraction technology. When the ionic liquid is used in weak fluorescence compound or biomacromolecule fluorescence detection, the detection fluorescence sensitivity can be greatly improved; the analysis and application values are high.

Preparation of ω-tetrahydropyran-2-ylsulfanylalkylmagnesium chlorides: Useful reagents for the synthesis of 1-(ω-mercaptoalkyl)-1,2- dihydrobuckminsterfullerenes (C60)

ω-Tetrahydropyran-2-ylsulfanylalkylmagnesium chlorides are prepared as Grignard reagents containing protected mercaptoalkyl chains, which are useful for the direct introduction of ω-mercaptoalkyl chains to electrophiles. In order to prove the usefulness of these reagents, they were reacted with buckminsterfullerene (C60) to give 1-(ω-mercaptoalkyl)-1,2- dihydrobuckminsterfullerenes after the deprotection of THP group with TFA.
