Summary: A simple dual acylhydrazone-functionalized gelator (G1) was designed and synthesized, forming a supramolecular organogel (G1-gel) in a mixed solvent of DMF-H2O. The gelator solution exhibits brilliant blue light when mixed with Mg2+ and can be erased by saliva or CO32-, leading to the preparation of a smart erasable writable material.

Summary: The introduction of multiple kinetic aggregation states (Aggs) into the self-assembly pathway can increase the complexity and flexibility of the self-assemblies. This was achieved by using a series of chiral and achiral d(10) Au-I bis(N-heterocyclic carbene, NHC) complexes, where the achiral complex could undergo self-assembly with multiple kinetic Aggs. The chiral Au-I self-assemblies exhibited nonlinear optical response of second harmonic generation (SHG) and could function as optical waveguides with strong emission polarization, while these properties were absent in the achiral analogue.

Summary: This study explores the importance and mechanism of chiral self-assembly and self-sorting in gold cluster systems. By introducing ligands with different chirality, unique chiral gold clusters with specific shapes were successfully synthesized. Both homochiral and heterochiral self-sorting processes were observed, as well as the transfer of chirality from ligands to gold clusters, resulting in changes in symmetry.

Summary: In this study, a novel luminescence assay based on platinum(II) complexes was introduced to detect RNA and achieve nucleolus imaging. The noncovalent interactions between platinum(II) complexes and RNA were induced by introducing a guanidinium group, resulting in strong RNA affinity and remarkable luminescence turnon. The unique properties of platinum(II) complexes, including low-energy red luminescence and large Stokes shifts, make them promising for nucleolus imaging with high signal-to-background ratios and potential biological applications.

Summary: The construction of a novel hybrid supramolecular polymer based on polyoxometalate (POM) was achieved through in situ self-assembly at the oil-water interface. The POM-based supramolecular polymer exhibited independent redox and competitive responsiveness. The strong binding energy at the interface allowed for the stabilization of liquids in nonequilibrium shapes, showing potential for fabricating reconfigurable all-liquid constructs.

Summary: Gold (III) complex-based amphiphiles in aqueous media have high structural sensitivity to external stimulations, which opens up new possibilities for soft functional material applications. In this study, a supramolecular assembly system of gold (III) amphiphiles controlled by counterions exchange is demonstrated. The luminescent properties of the gold (III) amphiphiles are enhanced by the introduction of σ-donating mono-alkynyl ligand. Furthermore, these gold (III) amphiphiles show good cytocompatibilities to human bone marrow-derived mesenchymal stem cells.
