A pH‐Sensitive Nanosized Covalent–Organic Polymer for Enhanced Tumor Photodynamic Immunotherapy by Hypoxia Relief and STAT3 Inhibition

Advanced Science, EarlyView.
The nanosized covalent organic polymer composed of photosensitizer porphyrin, pyruvate kinase inhibitor vitamin K3, and STAT3 inhibitor WP1066 is prepared for enhanced photodynamic immunotherapy by simultaneous hypoxia relief and STAT3 inhibition. Abstract Photodynamic therapy (PDT) is a promising cancer therapy modality by generating reactive oxygen ...

Exploration of Oxygen Reduction Reaction Catalyzed by FePPc and Pz‐FeTPr Conjugated Organic Polymer: Insights From Grand‐Canonical Density Functional Theory

Advanced Science, EarlyView.
At alkaline conditions (pH = 13), for FePPc and Pz‐FeTPr at low potential (less than 0.5 V), the ORR mechanism is the *O2 mechanism (O2→∗O2→∗OOH→∗O→∗OH→H2O${{\rm{O}}_2} \to ^*{O_2} \to ^*OOH \to ^*O \to ^*OH \to {H_2}O$), Fe is the active site; for Pz‐FeTPr at high potential (larger than 0.5 V), the Fe site is covered by O2−$O_2^ - $, the nearby C site

Fullerene C70‐Encapsulated Tetrathiafulvalene‐Co Porphyrin Covalent Organic Framework: Driving Multistep Charge Transfer to Boost CO2 Photoreduction

Advanced Science, EarlyView.
The encapsulation of C70 into COF has improved the efficiency of photocatalytic CO2 reduction significantly. The introduction of C70 drives multistep charge transfer and forms a long‐lived charge‐separated state. It also thermodynamically lowers the energy barrier of the rate‐determining step.
