Solvent Accommodation: Functionalities Can Be Tailored Through Co-Crystallization Based on 1:1 Coronene-F4TCNQ Charge-Transfer Complex

Because organic donor/acceptor blending systems play critical roles in ambipolar transistors; photovoltaics, and light-emitting transistors, it is highly desirable to precisely tailor the stacking of cocrystals toward different intrinsic structures and physical properties. Here, we demonstrated that the structure-stacking modes and electron-transport behaviors of coronene-F4TCNQ cocrystals(1:1) can be tuned through the solvent accommodation. Our results clearly show that the solvent accommodation not only enlarges the inner mixed packing (... DAD ...) distances, leading to the depressed short-contact interactions including the side-by-side and face-by-face intermolecular interaction, but also switches off electron-transport behavior of coronene-F(4)TCNQ cocrystals (1:1) in ambient atmosphere.
