A tetra(thiafulvalene-crown-ether) phthalocyanine self-assembles into helical tapes nanometers wide and micrometers long. Formation of these scrolled molecular architectures is a first for phthalocyanine fibres and shows potential as a novel conducting material.
A new method for the synthesis of formyltetrathiafulvalene vinylogs in which tetrathiafulvalene (TTF) or a substituted derivative of TTF is metalated with lithium diisopropylamide and then reacted with a vinylogous amide to yield the corresponding short polyenals in a one-pot process is described.

We report a novel set of easily tailorable C3 symmetric molecules with a π-extended core and adorned with different thioalkyl groups, exhibiting solvatofluorochromic and amphoteric redox behaviour. The nearly planar core exhibits intermolecular face-to-face π-stacking, S⋯S and intramolecular S⋯O interactions. Current-sensing atomic force microscopy studies revealed a high conductivity of ∼0.15 mS cm−1
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。

A TTF‐based (TTF=tetrathiafulvalene) tridentate ligand (α‐(4′‐methyl‐4,5‐di‐n‐dodecylthylthiotetrathiafulvalene‐5′‐ylthio)‐ α′‐[2,2,2‐tris(1‐pyrazolyl)ethoxy]‐p‐xylene) (L) with long‐chain alkyl moieties was prepared in order to obtain a new multi‐redox active gelator based on a mixed‐metal octanuclear complex [FeIII4NiII4(CN)12(tp)4(L)4](BF4)4 (1). The magnetism, electrochemistry, and gelation behavior

One‐dimensional charge‐transfer nanostructures were constructed by the supramolecular coassembly of amphiphilic (Amph‐TTF) and hydrophobic (TDD‐TTF) tetrathiafulvalene (TTF) donor derivatives with the acceptor 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ), in appropriate solvent composition mixtures. Microscopic analyses show that TDD‐TTF retains its self‐assembled fibrillar morphology even in
