a Large-scale STM image (200 nm × 120 nm; −2.0 V, 20 pA) of the 2D crystalline monolayer made of eight-membered macrocycles (M8). Inset: FFT pattern. b Zoom in STM image (−1.0 V, 50 pA) of the M8 2D crystal with overlaid simplified molecular models. The blue square denotes the unit cell. c, d High-resolution STM image (−1.0 V, 150 pA) and chemical model of M8, outlined by the dashed white line. Scale bar: 1 nm. e Schematic model of the M8 2D crystal.
