摘　　要：Exploration of efficient and stable photocatalysts to mimic natural leaves for the conversion of atmospheric CO_(2)into hydrocarbons utilizing solar light is very important but remains a major challenge.Herein,we report the design of four novel metal-salen-incorporated conjugated microporous polymers as robust artificial leaves for photoreduction of atmospheric CO_(2)with gaseous water.Owing to the rich nitrogen and oxygen moieties in the polymeric frameworks,they show a maximum CO_(2)adsorption capacity of 46.1 cm3 g^(−1)and adsorption selectivity for CO_(2)/N_(2)of up to 82 at 273 K.Under air atmosphere and simulated solar light(100mWcm^(−2)),TEPT-Zn shows an excellent CO yield of 304.96μmol h^(−1)g^(−1)with a selectivity of approximately 100%,which represents one of the best results in terms of organic photocatalysts for gas-phase CO_(2)photoreduction so far.Furthermore,only small degradation in the CO yield is observed even after 120-h continuous illumination.More importantly,a good CO yield of 152.52μmol g^(−1)was achieved by directly exposing the photocatalytic reaction of TEPT-Zn in an outdoor environment for 3 h(25-28℃,52.3±7.9mWcm^(−2)).This work provides an avenue for the continued development of advanced polymers toward gas-phase photoconversion of CO_(2)from air.
