The fabrication of molecular crystalline materials with fast, multistimuli-responsive behavior and the construction of the corresponding structure-activity relationship are of extraordinary significance for the development of smart materials. In this context, three multistimuli-responsive functional metal-organic polyhedra (MOP), {[Dy(bcbp)(NO)(HO)]·Cl·(NO)·HO} (), {[Dy(bcbp)(HO)]Cl} (), and {[Eu(bcbp)(HO)]Cl·HO} (; bcbp = 1,1'-bis(4-carboxyphenyl)-4,4'-bipyridinium), were successfully prepared and characterized. All of the compounds exhibit rapid and reversible photochromic and electrochromic dual-responsive behaviors. Furthermore, benefiting from the well-defined crystal structure and different responsive behaviors, the photoinduced electron transfer (PIET) process and structure-activity relationship were explored. In addition, considering the excellent photochromic performance, function filter paper and smart organic glass were successfully prepared and used for ink-free printing and UV light detection.

The reaction between molybdenum(ii) acetate and 5-aminoisophthalic acid (HIso-NH) afforded [MoO(μ-O)(Iso-NH)], a novel molybdenum(v) metal-organic polyhedron (MOP) with a triangular antiprismatic shape stabilized by intramolecular N-H⋯O hydrogen bonds. The synthesis conditions, particularly the choice of solvent and reaction time, led to the precipitation of the Mo(v)-MOP in five distinct crystalline forms. These forms vary in their packing arrangements, co-crystallized solvent molecules, and counter-cations, with three phases containing dimethylammonium (dma) and the other two containing diethylammonium (dea).

The oxygen evolution reaction (OER) is hindered by slow kinetics due to its four-electron process, limiting overall efficiency. The rational design of metal-organic framework (MOF)-based nanomaterials is crucial for enhancing the oxygen production rate. Using a straightforward strategy, we synthesized cobalt-iron layered double hydroxide (CoFe-LDH) hollow polyhedra loaded with CeO, with zeolite imidazolate framework-67 (ZIF-67) serving as the precursor.

This mini-review focuses on recent developments in hydroxamate-based metal-organic frameworks (MOFs), which exhibit unique structures and properties distinct from those of carboxylate-based MOFs. Hydroxamates (RCONHO) form MOFs with novel structural motifs and functionalities. In this review, synthetic strategies, structural characteristics, and functional applications of key examples of hydroxamate-based MOFs are described, providing insights into the influence of the hydroxamate ligand on the MOF properties compared to that of the carboxylate-based analogues.

Rechargeable batteries paired with lithium (Li) metal anodes are considered to be promising high-energy storage systems. However, the use of highly reactive Li metal and the formation of Li dendrites during battery operation would cause safety concerns, especially with the employment of highly flammable liquid electrolytes. Herein, a general strategy by engineering coordination-driven crosslinking networks is proposed to achieve high-performance solid polymer electrolytes.
