“…As a consequence of the high binding affinity, custom‐made terpyridine monomers combined with suitable metals give rise to programmable and highly ordered 2D and 3D structures . These supramolecular materials based on terpyridine‐containing p‐conjugated polymers found application in optoelectronic devices like organic light‐emitting diode, photovoltaic cells, organic field‐effect transistors and ion sensors , . Beyond this, the design of reversible and flexible metallo‐polymeric systems allows the integration of such architectures even in biological environments (e.g.…”

Exploring new materials to manipulate luminescent radiation and investigate the interaction of light and matter is one of the most compelling prospects of our century. Supramolecular chemistry has unraveled the opportunity to synergistically combine the chemical and optoelectronic properties of the most diverse classes of compounds. Among these, terpyridines have acted as pivotal ligand units that enable selfassembly of multicomponent chromophoric systems. In this review we therefore elucidate the metal-coordinating ability of [a]

“…Because of the nonplanar structure, the tetrasubstituted-derivatives using pyrene as core including 33 and 34 tend to afford low mobilities [90][91][92]. However, the derivatives 35 and 36 using pyrene as an end-capped group and linear pyrene derivative 37 showed high mobilities [93][94][95]. For example, thin film transistors based on derivatives 35, 36, and 37 exhibited mobilities of 0.21, 0.11, and 2.1 cm 2 V −1 s −1 , respectively.…”

An important application of organic semiconductors is to fabricate organic field-effect transistors (OFETs) which are essential building blocks for the next generation of organic circuits. In terms of molecular size or molecular weight, organic semiconductors can be divided into small-molecule and polymer semiconductors, and thus their corresponding OFETs can also be categorized into organic small molecule OFETs and polymer field-effect transistors (PFETs). On the basis of the main charge carriers transporting in OFET channels, organic semiconductors can be further divided into p-type, n-type, and ambipolar semiconducting materials. According to the characteristic of the organic semiconductors, the OFETs can be classified into two types: organic thin film transistors (OTFTs) and organic single crystal transistors. In any kind of OFET devices, organic semiconductor materials are the core; their properties determine the performance of the electronic devices. Therefore, the design and synthesis of high performance organic semiconductor materials are the basis and premise of the wide application of OFET devices. In the past few decades, great progress has been made in developing organic semiconductors. Besides organic semiconducting materials, there are many other factors influencing the performance of OFETs including device configuration, processing technique, and other devices physical factors, etc. In the following, a brief review of the development of p-type, n-type, ambipolar organic semiconductors and their field-effect properties is given. The history, mechanism, configuration, and fabrication methods of OFET devices and main performance influencing factors of OFETs are also introduced.

“…However, the Suzuki–Miyaura coupling using thiopheneboronic acids have been rarely applied in the synthesis of oligerthiophene in organic material chemistry . On the other hand, terthienyls are important structural units and usually can be directly derived to property‐specific π‐conjugated oligomers . Currently, the Kumada coupling using thiophene magnesium reagents and the Suzuki–Miyaura coupling using thiophene boron reagents of haloterthienyls have been frequently used in the synthesis of molecular functional materials .…”

A ligand-enabled Pd-catalyzed Suzuki-Miyaura coupling of haloterthienyls for the synthesis of various thiophene-based π-conjugated oligomers including quinquethiophenes is demonstrated. An indolyl phosphine ligand plays an important role in this transformation. Thiopheneboronic acids were well applied, which might open up a window for the application of thiopheneboronic acids in the synthesis of thiophene-based π-conjugated oligomers in materials chemistry.
