Self‐Assembly: Precisely Tailoring the Stoichiometric Stacking of Perylene‐TCNQ Co‐Crystals towards Different Nano and Microstructures with Varied Optoelectronic Performances (Small 18/2015)

A solution self-assembly method is reported by Y. G. Zhen, W. P. Hu, and co-workers to tailor the stoichiometric stacking of perylene-TCNQ co-crystals towards different nano/microstructures by tuning the solution donor and acceptor concentrations. One complex self-assembles into wire-like crystals while the other aggregates into block-like crystals. On page 2150, distinct molecular packing structures in the co-crystals influence their charge transport behavior and photoresponsivity, providing valuable insight into the rational design and controllable synthesis of organic co-crystals with desired functions.
