Published: Jan. 1, 2025

Stimuli-responsive polymers have garnered significant attention for their ability to adapt environmental changes, offering applications in sensing, smart coatings, and adaptive devices. However, challenges remain developing multifunctional that combine dynamic responsiveness with robust mechanical properties. In this study, we design synthesize azobenzene-based copolymers, poly(thiourea triethylene glycol)-co-azobenzene (PTUEG3-co-Azo) through a controlled polycondensation process address these limitations. The flexible PTUEG3 backbone, its strong hydrogen-bonding networks, is combined azobenzene moieties impart thermal isomerization, acid-base responsiveness, enhanced adhesion performance. groups exhibited thermally induced cis-to-trans leading structural reorganization, increased molecular packing, elevated glass transition temperatures (Tg). Additionally, the demonstrated reversible undergoing distinct repeatable color changes upon protonation deprotonation. By balancing flexibility of backbone rigidity groups, PTUEG3-co-Azo copolymers achieved performance tunable 4 : 1 composition superior adhesive strength, attributed synergistic effects hydrogen bonding azobenzene-induced reorganization under activation. These results present as versatile material, bridging gap between robustness, potential adhesives, functional coatings.

Sub‐10‐nm Lithography for Sn4–Oxo Clusters: Effect of Molecular Polarity on Sensitivity and Resolution

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

Published: April 7, 2025

Abstract Tin‐based metal–oxo clusters have recently garnered considerable attention in high‐energy irradiation lithography because of their nanoscale patterning capabilities. However, achieving sub‐10 nm resolution remains a challenge due to uncontrolled latent image gradients after exposure. In this study, the development mechanism Sn4–oxo cluster is investigated using molecular polarity index model. Resolutions 8 and 17 are successfully achieved for Sn4‐TF electron beam (EBL) extreme ultraviolet (EUVL), respectively. A novel pre‐irradiation modification strategy proposed enhance sensitivity by one‐third both EBL EUVL. The experimental findings theoretical analysis demonstrate that deep (DUV) primarily degrades organic ligands promotes Sn–O–Sn crosslinking, whereas EUVL drive hydrocarbon crosslinking among clusters. This study deepens our understanding Sn–oxo photolithographic reaction mechanisms, offering critical insights optimizing developers enhancing sensitivity. These expected aid realization node technology.
