Figure 5

(a) Chemical structure of DH-4T and the optical image of a water droplet on a 2D DH-4T film used for contact angle measurements. (b,c) Top-view and cross-sectional SEM images (b) and θ–2θ XRD pattern (c) of a 2D DH-4T film (the inset depicts a view of the edge-on molecular orientation with a calculated d-spacing of 2.63 nm along the [001] film growth direction). (d) SERS spectra of methylene blue (MB) on a pristine DH-4T film (the inset shows a schematic representation of the SERS measurement). (Reproduced with permission from ref (24).
