Regulating Enol-to-Keto Tautomerization of Pillararene-Based Conjugated Macrocycle Polymers for H2O2 Photosynthesis

. In-depth investigations reveal that the incorporation of pillararenes enables synergistic catalysis of water oxidation and oxygen reduction reactions and significantly enhances catalyst stability by regulating molecular tautomerization. This work opens new avenues for designing high-performance multifunctional conjugated macrocycle polymers with significant potential for clean energy conversion.
