Fig. 7

a Schematic showing the molecular structures of four electronic acceptors of OFN, TClP, TCNB, and TCNQ, as well as two electronic donors of BGP and BCP. b Morphology images of organic CT cocrystals of BGP-OFN, BGP-TClP, BGP-TCNB, BCP-TClP, and BCP-TCNQ microwires. The excitation of the corresponding FM images is UV light. c, d Organic barcoded microwires based on different combinations of organic CT cocrystals: c BGP-OFN@BGP-TClP, d BGP-OFN@BGP-TCNB, and e BCP-TClP@BCP-TCNQ. (i) FM image of the organic barcoded microwire, and (ii) the spatially resolved PL spectra corresponding to different locations marked domains in (i).
