^aReaction conditions: PO 30 mL, the Zn–Fe DMC complexes 0.5 g, CO₂ pressure 3 MPa, 60 °C 24 h.

^bTurnover number(TON) in g·polymer/g·Zn and turnover frequency in g·polymer/g·Zn h.

^cDetermined by ¹H NMR spectra. f_CO2 = (A_4.78 + A_4.06) × 44/(A_4.78 + A_4.06) × 44 + (A_4.78 + A_4.06) × 58 + A_3.27–3.73 × 58. f_PO = (A_4.78 + A_4.06 + A_3.24–3.71)/[2(A_4.78 + A_4.06) + A_3.27–3.73]. f_PC = (A_4.78 + A_4.06)/(A_4.78 + A_4.06 + A_3.27–3.73).
