Polarization engineering in porous organic polymers for charge separation efficiency and its applications in photocatalytic aerobic oxidations

Photocatalytic aerobic oxidation reactions are largely governed by the efficiency of charge separation and subsequent reactive oxygen species(ROS) generation. Herein, we report a polarization engineering strategy to promote the charge separation and ROS generation efficiency by substituting the benzene unit with furan/thiophene in porous organic polymers(POPs). Benefiting from the extent of local polarization, the thiophene-containing POP(JNU-218) exhibits the best photocatalytic performance in aerobic oxidation reactions, with a yield much higher than those for the furan-containing POP(JNU-217) and the benzenecontaining POP(JNU-216). Experimental studies and theoretical calculations reveal that the increase of local polarization can indeed reduce the exciton binding energy, and therefore facilitate the separation of electron-hole pairs. This work demonstrates a viable strategy to tune charge separation and ROS generation efficiency by modulating the dipole moments of the building blocks in porous polymeric organic semiconductors.

Dual-functional additive of cesium ion for achieving ultrahigh efficiency of persistent phosphorescence in existing polymer-based materials

Despite great achievements obtained for polymer-based room-temperature phosphorescence（RTP） materials, the limited efficiencies of persistent RTP still hinder their development. Herein, a simple and universal strategy of using the dual-functional additive of Cs+was presented, which could simultaneously enhance the efficiency（Φp） and maintain the long lifetime（τp） of RTP in existing polymer-based systems with various phosphors and polymers. Among them, the commercial emitter（TpB）-doped polyvinyl alcohol（PVA）/Cs2CO3system possessed an extremely high Φpup to 75.5% and still maintained a long τpof 2.13 s, by introducing the heavy-atom effect and an extra network of ionic bonding through the Cs+additive. Additionally, the temperature resistance of RTP in TpB@PVA/Cs+film could also be improved to 85℃. More satisfactorily, the efficiency of F?rster resonance energy transfer（FRET） from RTP to near-infrared（NIR） was also remarkably enhanced in the multi-component systems. This work provides a simple and universal strategy for developing polymer systems with high RTP performance.

Constructing the efficacious and applicable bifunctional electrocatalysts and establishing out the mechanisms of organic electro-oxidation by replacing anodic oxygen evolution reaction(OER) are critical to the development of electrochemicallydriven technologies for efficient hydrogen production and avoid CO_(2) emission. Herein, the hetero-nanocrystals between monodispersed Pt(~ 2 nm) and Ni_(3)S_(2)(~ 9.6 nm) are constructed as active electrocatalysts through interfacial electronic modulation, which exhibit superior bi-functional activities for methanol selective oxidation and H_(2) generation. The experimental and theoretical studies reveal that the asymmetrical charge distribution at Pt–Ni_(3)S_(2) could be modulated by the electronic interaction at the interface of dual-monodispersed heterojunctions, which thus promote the adsorption/desorption of the chemical intermediates at the interface. As a result, the selective conversion from CH_(3)OH to formate is accomplished at very low potentials(1.45 V) to attain 100 m A cm^(-2) with high electronic utilization rate(~ 98%) and without CO_(2) emission. Meanwhile, the Pt–Ni_(3)S_(2) can simultaneously exhibit a broad potential window with outstanding stability and large current densities for hydrogen evolution reaction(HER) at the cathode. Further, the excellent bi-functional performance is also indicated in the coupled methanol oxidation reaction(MOR)//HER reactor by only requiring a cell voltage of 1.60 V to achieve a current density of 50 m A cm^(-2) with good reusability.
