Organic heterostructures with precisely defined com-positions,architectures,and interfaces are consid-ered promising building blocks for integrated optoelectronic devices.However,it remains a great challenge to rationally design and synthesize a het-erostructure with tunable performance for promising applications such as optoelectronic devices.Herein,we report a universal strategy for the synthesis of organic lateral heterostructures(OLHs)with tunable function and optical properties.We fabricated cocrystals based on the tunable intermolecular dis-tance(dπ-π from 3.33 to 3.48 Å)of Benzo[ghi]perylene(BGP)-based driven by arene-perfluoroarene interac-tion or charge transfer interaction;these different components were selectively constructed into organ-ic solid solution microwires or OLHs.Importantly,the solid solution microwires obtained could be epitaxi-ally grown on the BGP-tetrabromophthalicanhydride trunk microwire to construct a series of OLHs micro-wires,which led to the successful demonstration of both photonic signal conversion and optical logic gate in all-color wavelength.This work gives a new insight into the fine synthesis of heterostructures with tunable structures/performances,providing predict-able synthetic pathways to multifunctional organic heterostructures for the future realization of integrat-ed optoelectronics.
