我们报告了一套新颖的易于定制的C 3对称分子,具有π延伸的核心,并装饰有不同的硫代烷基,表现出溶剂化的荧光色和两性的氧化还原行为。近似平面的核表现出分子间面对面的π堆积,S⋯S和分子内S⋯O相互作用。电流感测原子力显微镜研究显示,在未添加硫代丙基的胶凝剂的J型骨料纳米纤维中,电导率约为0.15 mS cm -1。
Bis-fused π-electron donors having alkylthio chains, CnTET-TTP (2-[4,5-bis(alkylthio)-1,3-dithiol-2-ylidene]-5-(4,5-ethylenedithio-1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene; n = 2–4) have been synthesized. C2TET-TTP (1a) forms radical-cation salts with BF4- and ClO4-, which are metallic (σrt = 900-2500 S cm-1) down to helium temperatures. The I3 salts of C3TET-TTP (1b) and C4TET-TTP (1c) are
A new approach to vinylogous TTF derivatives 5 via an alkyne-coupling reaction is reported. Their fundamental redox behavior has been studied. A proposed reaction mechanism, which accounts for the formation of compounds 5 is discussed.

molecular electronics. Protocols enabling the synthesis of functionalised MPTTFs and BPTTFs are therefore of broad interest. Herein, we present the synthesis of a range of functionalised MPTTF and BPTTF species. Firstly, the large-scale preparation of the precursor species N-tosyl-(1,3)-dithiolo[4,5-c]pyrrole-2-one (6) is described, as well as the synthesis of the analogue N-tosyl-4,6-dimethyl-(1,3)-dithiolo[4

Ullmann-type coupling reaction was employed for the preparation of several N-arylated monopyrrolotetrathiafulvalenes with variable substitution patterns. Spectroscopic and electrochemical properties of the coupling products strongly depend on the electronic nature of the aromatic substituents due to their direct conjugation with the tetrathiafulvalene chromophore. The crystal packing of the arylated
