Fig. 2: Core/shell microwires with component interchange.
From: Organic superstructure microwires with hierarchical spatial organisation
a Schematic representation of the horizontal epitaxial-growth approach for the organic core/shell microwires with component interchange. FM images of b BTB microwires with partly covering by BTP, c BTP/BTB microwires, and d BTP/BTB core/shell microwires with the scale bars of 20 μm. The microwires in (b1, c1, and d1) were excited with UV light (λ = 330–380 nm) from a mercury lamp. Although the microwires in (b2, c2, and d2) were excited with green light (λ = 500–550 nm) from a mercury lamp. e Schematic representation of horizontal epitaxial-growth process for the formation of BTB/BTP core/shell microwires. f Molecular arrangement and orientation at the junction of core/shell structure.
