Article Abstract
Three new cadmium coordination polymers, namely [Cd(NO₃)₂(DPNDI)(CH₃OH)]·CH₃OH (), [Cd(SCN)₂(DPNDI)] (), and [Cd(DPNDI)₂(DMF)₂]·2ClO₄ () (DPNDI = ,-di(4-pyridyl)-1,4,5,8-naphthalene diimide, DMF = ,-dimethylformamide) have been synthesized by reactions of DPNDI with Cd(NO₃)₂, Cd(SCN)₂, and Cd(ClO₄)₂, respectively. Compound is a one-dimensional coordination polymer with strong lone pair-π interactions between the coordinated NO₃ anions and the imide ring of DPNDI; while is a two-dimensional network with a (4, 4) net topology. In the case of , due to the presence of uncoordinated perchlorate counter ions, it exhibits a non-interpenetrated square-grid coordination polymer containing one-dimensional rhomboid channels. The structural diversity in these compounds is attributed to different coordination abilities and geometries of counter anions. Due to the presence of electron-deficient NDI moiety, the photochromic behavior of these compounds was studied. Interestingly, only compounds and exhibit color changes under light irradiation. The influence of the anions on the photochromism process of the NDI-based materials has been discussed.

[Cu(3-bph)(PABA)(HO)] () (3-bph = ,'-bis(3-pyridylmethylene)hydrazine and PABA = -amino benzoate) is a pyridyl-N bridging Cu coordination polymer, and PABA acts as a carboxylate-O donor forming a square pyramidal CuNO motif following a zigzag one-dimensional (1D) lattice. The shows weak antiferromagnetic coupling ( = -0.196(1) cm), and emission appears at 352 nm (λ = 293 nm), which is selectively quenched by Fe via the FRET mechanism.

As a new generation of high-energy-density energy storage system, solid-state aluminum-ion batteries have attracted much attention. Nowadays polyethylene oxide (PEO)-based electrolytes have been initially applied to Lithium-ion batteries due to their flexible processing and good interfacial compatibility, their application in aluminum-ion batteries still faces problems. To overcome the limitations in aluminum-ion batteries-specifically, strong Al coordination suppressing ion dissociation, high room-temperature crystallinity, and inadequate mechanical strength-this study develops a blended polymer electrolyte (BPE) of polypropylene carbonate (PPC) and PEO.

Understanding ion transport mechanisms in sodium ion-based polymer electrolytes is critical, considering the emergence of sodium ion electrolyte technologies as sustainable alternatives to lithium-based systems. In this paper, we employ all-atom molecular dynamics simulations to investigate the salt concentration () effects on ionic conductivity () mechanisms in sodium hexafluorophosphate (NaPF) in polyethylene oxide (PEO) electrolytes. Sodium ions exhibit ion solvation shell characteristics comparable to those of lithium-based polymer electrolytes, with similar anion coordination but more populated oxygen coordination in the polymer matrix.

Optimal skin healing is a sophisticated, coordinated process involving cellular and molecular interactions. Disruptions in this process can result in chronic wounds, necessitating medical intervention, particularly when the damage surpasses the body's regenerative capabilities. In response, novel therapies, especially tissue engineering and stem cell treatments, have been devised to restore tissue architecture and maximum functionality.

Polymer additives exhibit unique advantages in suppressing lead leaching from perovskite solar cells (PSCs). However, polymers tend to excessively aggregate in the perovskite film, which hinders comprehensive encapsulation and disrupts charge transport efficiency, degrading lead leakage inhibition and device performance. Herein, a polymer dynamic soft encapsulation strategy driven by molecular extrusion is introduced to mitigate lead leakage in PSCs, achieved through the incorporation of poly(propylene adipate) (PPA) as a multifunctional additive in the perovskite formulation.
