Distinctly different topological networks be obtained by judiciously introducing alternative π‐conjugated anionic guests, including a new structure (named sfm first reported in this work, describing 4,4,4,4‐c net. EPR data UV–Vis spectra prove mechanism. Dynamic photochromism exhibits tunability wide CIE color space, with linear segment from yellow to red for , while curved coordinate line resulting colorful emission blue orange. Moreover, photogenerated TEPE* activate near‐infrared (NIR) effect MOFs. Under W cm −2 808 nm laser irradiation, surface temperatures photoproducts 1* 2* reach ~160 °C ~120 °C, respectively, competitive NIR efficiencies η =51.8 % 36.2 ).

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

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 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. Photothermal temperatures ultimately transformation framework, attaining up 640 K within 15 s under 808 nm laser irradiation (1.7 W cm −2 ). Potential energy calculations single‐crystal data reveal driven varying affinities pore environments different
