By assembling the (4-fluorobenzyl)(triphenyl)phosphonium cation (FBTPP⁺) with tetrahedral cadmium(II) anions, we present four new hybrids, (FBTPP)₂[CdX₄] (X = Cl⁻, Br⁻, I⁻, NCS⁻ for <b>1–4</b>), forming a textbook-style comparative system to elucidate crystal-glass phase transformations. This series enables synergistic control over core properties: a centrosymmetric-to-noncentrosymmetric evolution (<i>Pbca</i> → <i>P</i>2₁/<i>c</i> → <i>Cc</i> → <i>Cc</i>), a 146 K melting point depression (515 → 369 K), a decreasing fragility index (41.8 → 30.3), and a marked GFA enhancement (0.70 → 0.83). These systematic trends originate from anion enlargement and electronic polarization, which weaken intermolecular contacts, reduce lattice cohesion, lower the melting barrier, and promote diffuse charge distributions, thus broadening structural relaxation near the glass transition and enhancing kinetic stability against recrystallization. The bulky, charge-delocalized NCS⁻ anion further induces a polar crystal packing with an open, loosened structure and greatly increased molecular separation. We further demonstrate a novel strategy that bypasses the kinetic limitation of recrystallization: a polar glass-ceramic thin film (<b>4-GC</b>) was fabricated under ambient conditions via direct consolidation of its glassy phase with polycrystalline <b>4</b> above the vitrification temperature, exhibiting a 2.4-fold enhanced second-harmonic generation response.

Here, we report a phase separation strategy that yields an LCE with a tensile strength of 92 MPa and toughness of 247 MJ m⁻³. This leads to 20-fold and 40-fold improvements compared with conventional LCEs without sacrificing their reversible actuation.

While freshly prepared samples are ECD-silent, aging triggers a giant dichroic response, with ellipticity values reaching approximately 18,000 mdeg, among the highest reported to date for thin films of chiral organic dyes as neat materials.

A thorough investigation, combining microscopy and spatially resolved chiroptical techniques with time-dependent density functional theory (TD-DFT) calculations, reveals that the intense chiroptical activity arises primarily from the consistent formation of right-handed three-dimensional (3D) helical architectures.

MPNs allow for precise control over coordination kinetics, stability, and functionality through diverse combinations of polyphenols and metal ions. Various assembly methods, including the template method, nanoprecipitation, layer-by-layer self-assembly, and one-pot synthesis, have successfully led to the construction of diverse structures such as films, nanoparticles, hollow capsules, hydrogels, and metal–organic frameworks. By adjusting the metal-to-polyphenol ratio, pH, reaction time, and introducing functional molecules, the size, surface charge, mechanical properties, and dissociation behavior of MPNs can be effectively controlled to meet the demands of various biomedical applications. Leveraging the synergistic interaction between paramagnetic or fluorescent metal ions and polyphenol structures, MPNs are widely used in the design of probes for magnetic resonance imaging, fluorescence imaging, photoacoustic imaging, and multimodal imaging, enabling precise localization and real-time monitoring of pathological sites. MPNs not only serve as highly efficient drug delivery carriers, enabling targeted release in response to the micro acidic or high reactive oxygen species environments of tumors, but also play a critical role in synergistic disease therapy through the enzymatic-like catalytic activity, photothermal conversion capabilities, and radiosensitizing effects of metal ions.
