Fig. 1: Illustration of the epitaxial-growth for organic superstructure microwires.
From: Organic superstructure microwires with hierarchical spatial organisation

a Schematic illustrations: (I) the horizontal epitaxial-growth mode for the organic core/shell microwires via a multistep seeded growth process and (II) the longitudinal epitaxial-growth mode for the organic multiblock microwires via a sequential crystallisation process. The red-emissive and green-emissive cartoon spheres represent the BTB and BTP cocrystal, respectively. Their chemical structures were shown in Supplementary Fig.1. b Schematic illustration of the combination of the horizontal and longitudinal epitaxial-growth modes for the organic superstructure microwires.
