“…This 3D network packing provides more electronic hoping channels for charge transfer, which should improve final electronic device performance. However, we stress that to date there are no reports on cocrystals based on Y6 structures, [38] and this would be a very interesting research direction in the OPV area. Overall, these single crystal structures offer us the possibilities to study the solid state packing in both single crystal and polycrystalline films, as well as perform theoretical computations for deeper understandings of the materials used in OPVs.…”

The advent of crescent-shaped Y6 and its derivatives have recently enabled exceptionally high solar cell performance metrics, for structural, physical, and transport characteristics that remain poorly understood. Here we summarize recent progress on crystallography, electronic structure, and device performance of this kind of non-fullerene acceptors. First, we discuss molecular engineering and the crystal structure of Y6 and its derivatives. Second, we present theoretical modeling of the molecular orbitals, reorganization energy, and electronic couplings. Third, we summarize single carrier diode and solar cell performance, and discuss the correlations between crystal structure and computational insights. Finally, we discuss unsolved problems and future developments in this field. Overall, this Minireview summarizes crystal structure, computational understanding, and device metrics, thus providing an outlook for future organic semiconductors design and mechanistic studies in fundamental research and industrial applications.

“…It should be stressed that the materials with anisotropic magnetoelectric coupling properties, which exhibit different energy densities of saturated (or spontaneous) magnetization in different crystal directions ( Palneedi et al, 2016 ), have potential applications in multiferroic memory devices ( Spaldin and Ramesh, 2019 ). Cocrystals have long-range ordered CT networks and largely delocalized π-electrons ( Zhu et al, 2021 ), providing more opportunities for guiding the magnetoelectric coupling of organic materials. Qin et al have proved the anisotropy of magnetization within C 60 -thiophene between in-plane (easy axis) and out-of-plane (hard axis) directions, which were attributed to the electron-phonon coupling tightly related to the molecular assembly axes and spin cone orientation ( Qin et al, 2015b ).…”

Cocrystal engineering is an advanced supramolecular strategy that has attracted a lot of research interest. Many studies on cocrystals in various application fields have been reported, with a particular focus on the optoelectronics field. However, few articles have combined and summarized the electronic and magnetic properties of cocrystals. In this review, we first introduce the growth methods that serve as the basis for realizing the different properties of cocrystals. Thereafter, we present an overview of cocrystal applications in electronic and magnetic fields. Some functional devices based on cocrystals are also introduced. We hope that this review will provide researchers with a more comprehensive understanding of the latest progress and prospects of cocrystals in electronic and magnetic fields.
