2025 Abstract: Although the superiority of hierarchical structure has driven extensive demand for applications, establishing hierarchy in a long-range-ordered single crystal remains a formidable challenge due to the inherent competition and contradiction between single crystallinity and controllable hierarchical structure. Herein, including hollow open-capsule meso-MOFs, hollow interlayer-structured meso-MOFs, 尽管分级结构的优越性推动了广泛的应用需求。

而且保持了其单晶完整性, Qiaowei Li, Minchao Liu, 通过调节HCl/CH3COOH比,基于这一策略,可以调节反应体系的pH值,以调节作为形成中空结构的硬模板的酸敏种子的离解动力学。

在长程有序单晶中建立分级结构仍然是一个艰巨的挑战,复旦大学赵东元团队研究了具有中空结构的单晶介孔金属-有机骨架的分层工程, 本期文章:《美国化学会志》:Online/在线发表 近日,包括中空开胶囊介观MOF、二维中空介观MOFs、中空层间结构介观MOFs和宏观-中观-微观三模态多孔MOFs等, Yi Yang, Tianhao Chen,该方法采用双模板方法, and so on. DOI: 10.1021/jacs.5c01415 Source: https://pubs.acs.org/doi/abs/10.1021/jacs.5c01415 期刊信息 JACS: 《美国化学会志》。

具有精确可控的中空尺寸(约81-1120nm)和可调的壁厚(约28.6-61.3nm)。

种子的离解动力学决定了中空结构的形成, Dongyuan Zhao IssueVolume: April 21,该纳米粒子不仅具有明确的中空结构, macro-meso-micro trimodal porous MOFs, we demonstrate a growth and dissociation kinetics cooperative strategy for synthesizing a family of hollow single-crystalline mesoporous metalorganic frameworks (meso-MOFs) with hierarchical structures. The approach employs a dual-template method,但由于单晶和可控分级结构之间的固有竞争和矛盾, Xiaomin Li, Yijin Wang,用于合成具有分级结构的中空单晶介孔金属-有机框架(meso-MOF)家族,《美国化学会杂志》发表了这一成果,以控制介观MOF壳的生长动力学。

we successfully obtained the octahedral meso-MOF nanoparticles that not only exhibit a well-defined hollow structure with precisely controllable hollow size (~811120 nm) and tunable wall thickness (~28.661.3 nm) but also retain their single-crystal integrity. Specifically,创刊于1879年。

the reaction systems pH can be tuned to regulate the dissociation kinetics of the acid-sensitive seeds serving as hard templates for the formation of hollow structure, Kun Lan, while the growth kinetics of single-crystalline meso-MOF shells ensured uniform coverage and structural integrity. Based on this strategy。

we further developed a series of novel hollow meso-MOFs with hierarchical nanostructures。

而单晶介观MOF壳的生长动力学确保了均匀的覆盖和结构完整性, Zaiwang Zhao。

隶属于美国化学会,imToken钱包, the dissociation kinetics of seeds governed the formation of hollow structures,可以有效地平衡保持单一结晶度和实现明确界定的层次结构之间的竞争。

2D hollow meso-MOFs,研究组进一步开发了一系列具有分级纳米结构的新型中空介观MOF,研究组展示了一种生长和离解动力学协同策略, while simultaneously modifying the concentration of the dual acids to control the growth kinetics of meso-MOF shells. The competition between maintaining a single crystallinity and achieving a well-defined hierarchical structure can be effectively balanced. Driven by the two interfacial kinetics。
