In the unabated quest for novel birefringent genes, we have figured out that π-conjugated aminopyrazine, [APZ], is capable of producing low-dimensional linear structures for achieving enhanced birefringence due to their structural diversity and inherent anisotropy. Herein, the systematic substitutions of non-π-conjugated [(H2PO4)- and (BF4)-] with heteroatom-substituted tetrahedral anions [(CF3SO3)-, (NH2SO3)-, (CH3SO3)-] and subsequently with the aliphatic [C4H6O4] anion, while keeping the cationic end constant, yield a series of seven compounds with a significant boost in Δncalc = (0.145-0.658@546 nm) which is optimal in their respective families. The substantial increase in birefringence is ascribed to dimensional transition and the propensity of [APZ] to form low-dimensional frameworks, modulated by hydrogen bonds. The intralayer [N-H⋯O], [O-H⋯N], and [N-H⋯F] interactions regulate the perfect coplanar arrangement (ϑ = 0°) of birefringent active units resulting in more pronounced in-plane anisotropy. Moreover, theoretical calculations corroborate that the sequential anion exchange brings variations in optical polarizability, leading to superior linear optical performance of birefringent materials. This work presents a novel birefringent gene, offering promising prospects for synthesizing compounds with exceptional birefringence within low-dimensional systems.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, owing to the widespread disordered physicochemical bonding and unpredictable internal phase separation phenomenon, traditional materials show a complex nonlinear correlation between the material structure and its performance, which makes it difficult to accurately adapt to the performance requirements of various specific application scenarios. In view of the above challenges, this paper innovatively proposes a strategy to achieve linear programmability in the mechanical properties of polymer elastomer materials. Instead of increasing the entropy value of the material, which may be brought about by the traditional physical composite method, this strategy adopts a unique path of introducing special dynamic chain segments (AlPUs). This innovative design leads to a highly ordered microscopic hydrogen bonding arrangement within the elastomer, which effectively reduces the free volume within the material, thus bringing the mechanical response of the material closer to the ideal state. Furthermore, by fine-tuning the content of material components, we are able to achieve linear control of key mechanical indexes, such as tensile strength and elongation at break, which is a significant advantage in terms of precision, range of adjustment, and versatility. The successful implementation of this work opens up a new way toward logical, fine and intelligent design and preparation of polymer materials, providing a solid materials science foundation and unlimited possibilities to promote technological innovation and development in the field of future major equipment and infrastructure.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the fundamental principles governing glass formation and crystallization in these materials remain elusive, significantly limiting their multifunctional applications. Here, high glass formation ability and tunable crystallization of glass are achieved through the regulation of intermolecular interactions. The π⋯π and C-H⋯π interactions among Bzmim+ (Bzmim = 1-benzyl-3-methylimidazolium) cations increase the melt viscosity and packing inefficiency of the structure, thereby facilitating the high glass formation ability of Bzmim3SbCl6 (B3SC6) and Bzmim2SbCl5 (B2SC5). The crystallization behaviour of these glasses is closely related to electrostatic attraction. The stronger electrostatic attraction and larger melt fragility in B3SC6 lead to a longer cooperative length of the supercooled liquid above Tg, resulting in a reversible and rapid crystal-glass transformation accompanied by high contrast luminescence switching upon heating. Conversely, the weaker electrostatic attraction and smaller melt fragility in B2SC5 result in a stable glass, and transparent glass ceramic can be fabricated by assisted nucleation and slow crystallization growth. This work highlights the important impact of intermolecular interactions on the formation and crystallization of OIMH glass, providing a design framework for engineering tailored properties for advanced applications in nonvolatile memory and photonic devices.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polymer-based porous films are promising PRC materials, but their low ultraviolet (UV) durability and lack of recyclability limit their long-term and widespread application. Herein, a recyclable polymer-based porous radiative cooling film with excellent ultraviolet durability was developed as the covering of a building. Owing to the Mie scattering effect of the porous structure and strong infrared emittance of ethyl cellulose, the film demonstrated a radiative cooling capability of 10.6 °C at a solar irradiance of 510 W m−2. The calculated energy consumption results indicated that the average cooling consumption reached 429.4 kW h, and 31% of the cooling energy could be saved. Notably, owing to the conjugated benzene ring structure of styrene–ethylene–butylene–styrene (SEBS), the film blocked most of the incident UV radiation and diffused the absorptive energy through the delocalization effect of electron clouds. Thus, the film retained high solar reflectivity after continuous UV exposure for 240 h. Notably, the film could be cyclically utilized using a simple nonsolvent-induced phase separation (NIPS) approach.

DNPQ, with its sextuple-active carbonyl/nitro motifs (H-bonding acceptors), was found to be uniquely prone to redox-coupling with tetrahedral NH4+ ions (H-bonding donors) while excluding sluggish Zn2+ ions, owing to a lower activation energy (0.32 vs. 0.43 eV). NH4+-coordinated H-bonding electrochemistry overcame the instability of the DNPQ cathode in aqueous electrolytes and enabled rapid redox kinetics of non-metal NH4+ charge carriers. As a result, a three-step 3e- NH4+ coordination with the DNPQ cathode achieved large-current survivability (50 A g-1) and long-lasting cyclability (80 000 cycles) for ZOBs.
