Precisely Tailoring the Stoichiometric Stacking of Perylene‐TCNQ Co‐Crystals towards Different Nano and Microstructures with Varied Optoelectronic Performances

Organic charge-transfer co-crystals with varied donor-acceptor stoichiometric ratios and molecular packing structures are controllably prepared with the morphology of nanowires or microblocks. They have distinct charge transport behavior and photoresponsivity. These interesting results pave the way for rational design and preparation of co-crystals with desired functions.
