We have synthesized a zwitterion-like molecule 1 having an N,N,N-tridentate ligand site for metal complexation. Compound 1 exhibited negative solvatochromism of the intramolecular charge-transfer (ICT) band in its UV–visible absorption spectrum for different polarity of solvents. Its anion radical (1−•) was generated from both electrical and chemical reduction of the p-naphthoquinone moiety.

Abstract An amphiphilic tetrathiafulvalene molecule was designed and readily synthesized. The am-TTF can gelate a variety of organic solvents in view of multiple intermolecular interactions, especially in polar solvent. SEM observation provided clear evidence for the self-assembled micro/nanofibers morphologies in gelation state. Moreover, XRD measurements indicated the formation of highly-ordered
摘要设计了一种两亲性四硫富瓦烯分子,易于合成。考虑到多种分子间相互作用,尤其是在极性溶剂中,am-TTF可以使多种有机溶剂胶凝。SEM观察为凝胶状态下的自组装微纤维/纳米纤维形态提供了清晰的证据。此外,XRD测量表明形成了高度有序的柱状结构。FT-IR光谱表明,在1700 cm-1以上的吸收中形成了混合价态,显示出电导率为10-4 S / cm时的半导体行为。基于am-TTF的导电纤维可能是有机电子产品的有前途的候选材料。

Benzocyclohexa-2,5-diene-1,4-dione-1,3-thiole-2-thione (2) was synthesized starting with 2,3-dichloronapthoquinone (1). Compounds 3 and 4 were also obtained; however, the yield of 2 can be increased through control of the temperature and reaction time. Reaction of 2 with triethylphosphite gave 5 and the tetrathiafulvalene ester 6. The tetrathiafulvalenequinone (9) was obtained by hydrolysis of 6 followed by oxidation of & Compound 9 was obtained more directly by hydrogenation of 2 followed by coupling with triethylphosphite and oxidation. Chloranil was used to prepare the dithiafulvene quinone 12 which was reduced, coupled with triethylphosphite to form, presumably, polymer 13. The reactions were repeated using the hexanoic acid esters of the corresponding hydroquinone thiafulvalenes. The crystal structures of 2, 3, 4, 5, 6a and 10 were determined by X-ray diffraction. Cyclic voltammetry studies show the tetrathiafulvalene quinones reduce like quinones, but do not exhibit the oxidation properties of tetrathiafulvalenes.
