“…[130] Furthermore, there is considerable current interest in TTF-based supramolecular chemistry, and redox-active TTF-containing oligomers, polymers, and dendrimers have been synthesized. [131] There have been only a few reports of TTF-fused macrocycles. Mono-, bis-, and tris(tetrathiafulvaleno)hexadehydro [12]annulenes 178-181 were reported by Iyoda and coworkers (Figure 44).…”

One of the most important objectives in materials, chemical, and physical sciences is the creation of large conjugated macrocycles with well-defined shapes, since such molecules are not only theoretically and experimentally interesting but also have potential applications in nanotechnology. Fully unsaturated macrocycles are regarded as models for infinitely conjugated π systems with inner cavities, and exhibit unusual optical and magnetic behavior. Macrocycles have interior and exterior sites, and site-specific substitution at both or either site can afford attractive structures, such as 1D, 2D, and 3D supramolecular nanostructures. These nanostructures could be controlled through the use of π-extended large macrocycles by a bottom-up strategy. Numerous shape-persistent π-conjugated macrocycles have been synthesized, but only a few are on the nanoscale. This Review focuses on nanosized π-conjugated macrocycles (>1 nm diameter) and giant macrocycles (>2 nm diameter), and summarizes their syntheses and properties.

“…[40] In this context, the improvement of conductivity through intermolecular interactions of the closely assembled gelator molecules in the gel state is significant, thus providing a bulk conducting nanowire. [40][41][42] Even though such supramolecular wires offer many advantages, controlling the self-assembly process during gelation is a challenging task. Therefore, in many cases, conducting properties were investigated for both the film state and nanostructures formed from solutions of different substrates.…”

Nature excels at engineering materials by using the principles of chemical synthesis and molecular self-assembly with the help of noncovalent forces. Learning from these phenomena, scientists have been able to create a variety of self-assembled artificial materials of different size, shapes, and properties for wide ranging applications. An area of great interest in this regard is solvent-assisted gel formation with functional organic molecules, thus leading to one-dimensional fibers. Such fibers have improved electronic properties and are potential soft materials for organic electronic devices, particularly in bulk heterojunction solar cells. Described herein is how molecular self-assembly, which was originally proposed as a simple laboratory curiosity, has helped the evolution of a variety of soft functional materials useful for advanced electronic devices such as organic field-effect transistors and organic solar cells. Highlights on some of the recent developments are discussed.

“…Recently, several TTF-py(py = pyridine) compounds have been reported, which the pyridyl group is directly attached to the TTF core without any spacer part, which could increase the electronic coupling between the TTF moiety and the pyridine group [7][8][9][10][11][12]. And our group also reported a TTF-py donor molecule, EDT-TTF-4-py, L1 (Scheme 1) could form microstructures by the coordinative self-assembly method [13].…”
