Cocrystal engineering of molecular rearrangement: a “turn-on” approach for high-performance N-type organic semiconductors

Abstract

Developing novel high-performance n-type semiconductors is of great importance for the future organic electronics. The complicated synthesizing procedures of new electron deficient backbones or chemical modification to control the energy...

Transistor Properties of Charge-Transfer Complexes─Combined Requirements from Energy Levels and Orbital Symmetry

“…The observed properties are sometimes susceptible to fabrication and measurement conditions. Nevertheless, applications of the above two criteria to calculations estimated from the crystal structures provide us a good starting point to roughly predict the phenomena in many cases. − Among the “inherently ambipolar” complexes, the actual characteristics and particularly the electron/hole balance considerably depend on the electrode materials and lead to apparently monopolar behavior in some cases …”

Molecular-Shape-Controlled Binary to Ternary Resistive Random-Access Memory Switching of N-Containing Heteroaromatic Semiconductors

“…With the increasing demand on ultrahigh-density data-storage (UHDDS) systems in advanced information processors and flexible electronics, the prospect of adopting organic materials as memory medium in UHDDS semiconductors has aroused more attention. − Organic materials afford attractive merits of low cost, easy processing, excellent miniaturization potential, and few environmental footprints as compared to inorganic electronics. − In addition, organic memory materials hold promise to realize UHDDS since their structures can be tuned at the molecular level to induce multiple resistive switching characteristics. Attributed to their structural adjustability and scalability, not surprisingly, organic molecules have been demonstrated as promising materials for high-performance semiconductors such as organic photovoltaics, , organic field-effect transistors, , organic light-emitting diodes, , and organic batteries. , Their application in organic resistive random-access memory (ReRAM) is currently also under progress.…”

An organic cocrystal based on phthalocyanine with ideal packing mode towards high-performance ambipolar property

“…14 However, the p-extension degree is low in most of the cocrystals reported so far due to poor solubility, leading to difficulty in assembling into a cocrystal. Third, the solid-state supramolecular structure of cocrystals is of paramount importance for their device properties 15 but suffers from difficulty in control. Hence, more efforts should be made towards developing new cocrystals with large p-conjugated backbones, which, in turn, will direct the rational selection of constituent molecules and reveal the structure-property relationship.…”
