Abstract Three triazine‐based conjugated porous polymers (CPPs) are synthesized via a Pd‐catalyzed Suzuki‐Miyaura coupling reaction between derivatives of 2,4,6‐tri(thiophen‐2‐yl)‐1,3,5‐triazine (TTT) and 2,4,6‐triphenyl‐1,3,5‐triazine (TPT). Photocatalysis experiments demonstrate that the hydrogen evolution rate (HER) ThTh‐CPP (homopolymer TTT) reach an exceptional 46.4 mmol g⁻¹ h⁻¹ without co‐catalysts, surpassing ThPh‐CPP (8.26 h⁻¹, copolymer TTT TPT) PhPh‐CPP (3.06 homopolymer TPT), as well nearly all similar polymer‐based catalysts reported to date, under visible light. The variance in photocatalytic activity is attributed differences linkage units on triazine ring. Mechanistic analysis, combining experimental theoretical studies, highlights potential engineering electron‐donating ability enhance polymers.

Recent insights into covalent organic frameworks (COFs) provide an opportunity for developing new sonosensitizers with the advantages of both small molecules and inorganic nanoagents. Herein, we synthesize two benzotrithiophene-based imine-linked COFs (BTT-DPh-COF BTT-DPy-COF) through density-functional-theory-guided structure editing. The tailored donor-acceptor (D-A) structures optimize band position endow them good intrinsic sonodynamic activity, which can efficiently kill cancer cells, showing excellent therapeutic effect. Particularly, because enhanced D-A effect that promotes charge separation transfer behavior, BTT-DPy-COF exhibits superior ultrasound-triggered reactive oxygen species (ROS) generation capability than BTT-DPh-COF. Therefore, these studies highlight great potential elaborate editing configurations as suitable candidates advanced sonosensitizers.

Recent progress in conjugated polymer photocatalysts has opened avenues for enhancing photocatalytic hydrogen production (PHP) activity through structural design. This study highlights the impact of acceptor-to-donor feed ratio on PHP copolymers, influencing their energy level structures. Five porous polymers (CPPs) were synthesized by adjusting molar ratio. Notably, at a 2:1 ratio, demonstrated high evolution rate (HER) 61.9 mmol g−1 h−1 under full arc irradiation without co-catalysts and an apparent quantum yield (AQY) 7.77% 475 nm. However, further increasing proportion donor unit copolymers decreases HER. Experiments theoretical simulation characterized that ratios effectively tune polymer's molecular structure, hydrophilicity, band gap, generation transport efficiency photo-induced charge carriers, ultimately affecting kinetics efficiency. research demonstrates tuning structure chemical compositions CPPs statistical copolymerization significantly impacts activity.
