Summary: A metallosupramolecular polymer network (DSPy subset of SHP5@Zn) was constructed by hierarchical self-assembly of a double-armed pillar[5]arene host (SHP5), a ditopic guest (DSPy), and Zn2+ ions, with host-guest recognition and metal-ligand coordination interactions playing a crucial role. The DSPy subset of SHP5@Zn assembly exhibits reversible sol-gel transition properties in response to various external stimuli, making it an excellent candidate for constructing smart gels. In addition, it can be used as a highly selective dual-channel sensor for OH anions, facilitating the development of a convenient test kit for OH sensing.

Summary: The design of novel drug delivery systems is crucial in disease treatments, and mesoporous silica nanoparticles (MSNs) have shown great promise due to their stability, tunable morphologies/sizes, and loading capability. Functionalization of MSNs with drugs, imaging, and targeting agents is enabled by the presence of surface silanol groups, making them versatile and popular among researchers. Stimuli-responsive silanol conjugates have emerged as an effective way to deliver therapeutic drugs precisely and on-demand, and it is important to understand the role of surface silanols in MSN as a drug delivery platform. This review provides an analytical understanding of surface silanols, their chemistry, identification methods, and their correlation with properties and performance.

Summary: This study introduces new suprastructure products composed of C-60-ethylenediamine microparticles and silver nanoparticles, loaded onto surfaces of microparticles through electrostatic adsorption. These products can be deposited onto indium tin oxide electrodes by electrostatic deposition, generating cathodic photocurrents in the presence of ascorbic acid and oxygen. The photocurrent generation suggests a combination of silver-nanoparticle-mediated electron transfer in the cathodic direction and plasmon-induced charge separation in the anodic direction.
