High‐quality mixed crystals with mixing‐ratio‐dependent lattice parameters and electronic structure are obtained by co‐deposition of two organic molecules. Using the mixed films as the inducing layer in weak epitaxy growth, the mobility of VOPc transistors is finely tuned. This is possible because of the cooperative effect between the tunable lattice parameters and electronic structure.
