P-GOMs for multiple molecules separation. a Temperature-dependent rejection rates of P-GOMs to Cu²⁺, [Fe(CN)₆]³⁻, RB, CBB, and Cyt. c, implying smaller channel size of the P-GOMs with the increasing temperature. Error bars, s.d. (n = 3). b Schematic diagram of the separation mechanism of P-GOMs towards mixed molecules solution. c Separation of mixed molecules solution, containing Cu²⁺, RB, and Cyt. c. d The digital photos of the mixed molecules feed solution, retentate at 50 °C, filtrate at 50 °C, filtrate at 25 °C, and retentate at 25 °C. e The UV-vis absorption spectra of pure RB aqueous solution, Cyt. c aqueous solution, mixed molecules solution, filtrate obtained at 50 °C and 25 °C, and retentate at 25 °C
