The size control of 1D organic arrays by tuning pressure and solution concentration. a–f AFM images of an individual organic single-crystal nanobelt with the width of ca. 1.5 μm but different heights varying from 8.3 nm to 168.1 nm. Their operating conditions are a and b 1 mg mL⁻¹ 14 MPa, c and d 1 mg mL⁻¹ 12 MPa, e 1 mg mL⁻¹ 8.0 MPa, f 1 mg mL⁻¹ 6.0 MPa, respectively. g Tunable thickness of nanobelts at different solution concentrations varying from 1 to 5 mg mL⁻¹ under different pressures varying from 5.5 to 14 MPa. Scale bars: f 1 μm
