Summary: This study presents a general strategy to construct highly emissive perylene diimide-based metallacycles via self-assembly. The fluorescence quantum yields of these assemblies exceed 98%, and they exhibit sensitive fluorescence responses toward picric acid. This research not only provides a rational strategy for preparing highly emissive bowtie-shaped metallacycles, but also sheds light on their usage in the detection of picric acid and associated compounds.

Summary: The coordination-driven self-assembly methodology is a versatile synthetic tool for obtaining complex discrete structures such as interlocked, chiral, or heteroleptic cages. Efforts have been made to control host-guest affinity, particularly in targeting substrate transportation and releasing. Redox-stimulation offers novel possibilities for controlling the host-guest binding affinity and triggering guest release.

Summary: A hexaphenyltriphenylene-based hexatopic pyridyl ligand is designed and used to prepare three hexagonal prismatic metallacages via metal-coordination-driven self-assembly. The metallacages show good host-guest complexation with emissive dyes, which can be used to tune their emission in solution. A mixture of the host metallacages and the guests exhibits white light emission based on their complementary emission colors.

Summary: By manipulating the host-guest chemistry of CB[5] and zinc ions, the electric double layer (EDL) structure at the zinc interface can be reconstructed, inhibiting dendrite deposition and improving the Coulombic efficiency. The CB[5] also has a strong host-guest interaction with zinc ions, allowing rapid transport of zinc ions while hindering water radicals and sulfate ions. This work opens up a new avenue for the development of rechargeable zinc metal batteries.

Summary: Molecular doping is a useful approach for tuning the optoelectronic properties of organic materials, especially crystalline luminescent semiconductors. The compatibility and selection criteria between host and dopant materials are still unclear. This study shows that molecular planarity, short molecular axis, and side polar substituents are critical for successful host-guest molecular doping, while heterocyclic unit type and arrangement, molecular long axis, conjugation chain length, and terminal substituents do not affect host-dopant compatibility.

Summary: We report the self-assembly of a supramolecular pseudo-cube formed from six perylene diimides (PDIs), which suppresses aggregation and allows for non-aggregated, monomer-like properties. The stabilized excited state in the cage enables delayed fluorescence, acting as an excited-state reservoir. This self-assembly technique provides a powerful tool for controlling the electronic properties of chromophores and advancing molecular electronics devices.

Summary: This study introduces a stimuli-responsive invisible ink for time-dependent encryption of information, which displays time-dependent photochromic behavior with tailorable fading rates by controlling the density of host-guest crosslinks. Encryption security of information is achieved through selectively placing host and guest competitors and UV patterning, providing an initially false image that gradually reveals the encrypted data.

Summary: Spin-crossover (SCO) metal-organic cages have the potential to be used as magnetic sensors and switches. Variations in the donor strength of heterocyclic aldehyde subcomponents in imine-based ligands can tune the ligand field for a Fe-II center, resulting in diverse SCO behaviors in the cages. The tetrahedral SCO cage built from 1-methyl-1H-imidazole-2-carbaldehyde can encapsulate various guests and stabilize different cage spin states depending on guest size. The SCO tetrahedron also exhibits different affinities for guests in different spin states, which is attributed to subtle structural differences caused by the change in the metal center spin state.

Summary: Two erbium(III) complexes, [ErCl(OArAd)3][Na(THF)6] (1) and Er(OArAd)3 (2), were prepared using a hard base ligand with large steric hindrance. The change in coordination geometry around the Er(III) site from distorted tetrahedral to flat trigonal pyramid geometry in different solvent environments enhanced the single-molecule magnet (SMM) behavior, with a field-induced effective energy barrier (Ueff) of 43(1) cm -1 for the latter. The study demonstrates the importance of a strong equatorial ligand field and high local symmetry in suppressing quantum tunneling of the magnetization (QTM) to achieve high-performance erbium(III)-based SMMs.

Summary: Two dichloride-bridged dinuclear dysprosium(III) complexes based on salen ligands, [Dy(L-1)(mu-Cl)(thf)](2) and [Dy-2(L-2)(2)(mu-Cl)(2)(thf)(2)], were reported. Complex 2 showed clear slow relaxation of the magnetization due to the two short Dy-O-(PhO) bonds with an angle of approximately 143 degrees, while complex 1 exhibited slower relaxation due to an angle of around 90 degrees. The structural difference in the relative angles of the two O-(PhO)-Dy-O-(PhO) vectors in these complexes resulted in significant differences in their dipolar ground states, leading to open magnetic hysteresis in complex 3 and not in complex 2.

Summary: In this study, the zero-field splitting (ZFS) of Gd3+ pentagonal bipyramidal complexes was investigated to understand the mechanisms of ground state splitting. The results showed that the ZFS is dominated by the B20 term, which is inversely proportional to the donor strength of the axial ligands. Additionally, the magnitude of B20 was found to be inversely proportional to the thermal barrier for the reversal of the magnetic moment of the corresponding isostructural Dy3+ complexes.

Summary: A novel CrII-dimeric complex has been constructed using a bulky silyl-amide ligand. The crystal structure analysis reveals a binuclear motif with two equivalent tetra-coordinate CrII centers displaying quasi-square planar geometry. Magnetic studies and theoretical calculations indicate the presence of slow dynamic magnetic relaxation and a non-negligible ferromagnetic coupling in the dimeric Cr-Cr units.

Summary: This research reports the synthesis, characterization, and crystal structure of a dynamic triradical species formed through the self-assembly of two molecules via a Lewis acid coupled electron transfer. The crystalline species is spin-frustrated without Jahn-Teller distortion at low temperature, while it dissociates back to diamagnetic starting material in solution at high temperature. The reversible process is tracked by variable-temperature NMR, EPR, and UV-vis-NIR spectroscopy. Isolation, property study, and dynamic bonding investigation on such a species lay the foundation for the design of functional polyradicals with potential application as memory or switching devices.
