Thermo‐Guest Programmable Structural Adaptability with Bistable Empty States and Photothermal Conversion in a Coordination Framework

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 19, 2025

Abstract Stimuli‐responsive programmable materials exhibit remarkable potential for smart applications due to their ability attain multi‐stable states through structural adaptability upon guest molecule removal or exchange. However, achieving designability remains challenging, particularly in maintaining the crystallinity single‐crystal‐to‐single‐crystal (SCSC) transformations and ensuring tunable activation. In this study, it is demonstrated that SCSC between an empty monoclinic framework triclinic can be manipulated stimuli combining various activations molecules. Reversible switching facilitated by MeOH adsorption heating‐induced transformations, whereas H 2 O alone cannot directly induce transformation. Instead, must first adsorb N,N ‐Dimethylformamide (DMF) molecules form a new DMF‐adsorbed subsequently undergoes mild activation yield framework. These interconvertible frameworks differ photothermal conversion performance selectively cause discoloration of CuSO 4 ·5H dehydration.

Machine Learning‐Assisted Design of Nitrogen‐Rich Covalent Triazine Frameworks Photocatalysts

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 19, 2024

Abstract Covalent triazine frameworks (CTFs), noted for their rich nitrogen content, have attracted significant attention as promising photocatalysts. However, the structural complexity introduced by diversity of atoms in nitrogen‐rich CTFs poses a substantial challenge discovering high‐performance CTFs. To address this challenge, machine‐learning approach is developed to rationally design CTFs, which subsequently validated through experimental methods. A framework employed based on special orthogonal group three dimensions (SO(3))‐invariant graph neural networks predict photocatalytic properties structures. This achieves exceptionally high accuracies with R 2 scores exceeding 0.98. From dataset 14920 structures, identifies 45 candidates. Guided these predictions, novel CTF structure, pyridine‐2,5‐dicarbaldehyde (CTF‐DCPD) selected and successfully synthesized, exhibits an ultrahigh hydrogen evolution rate 17.70 mmol g −1 h . significantly surpasses that widely studied CTF‐1,4‐dicyanobenzene (CTF‐DCB, 10.41 ). work provides new paradigm machine learning accelerate materials development, can be generalized development other functional materials.

Abstract Understanding charge carrier transfer at heterojunction interfaces is critical for advancing solar energy conversion technologies. This study utilizes continuous wave (CW), pulse, and time‐resolved (TR) electron paramagnetic resonance (EPR) spectroscopy to explore the radical species formed TAPA (tris(4−aminophenyl)amine)‐PDA (Terephthaldicarboxaldehyde)/ZnIn 2 S 4 (TP/ZIS) interface. CW pulse EPR identify stable defects localized near interface, accessible water molecules. Time‐resolved reveals a photoinduced from TP ZIS, leading generation of spin‐correlated pairs under light irradiation, signifying efficient separation spatial within S‐scheme heterojunction. mechanism, confirmed through in situ X–ray photoelectron femtosecond transient absorption spectroscopy, suppresses undesirable recombination, extending lifetimes.
