In this work, we explore the possibility of promoting the formation of ordered microphases by confinement of colloids with competing interactions in ordered porous materials. For that aim, we consider three families of porous materials modeled as cubic primitive, diamond, and gyroid bicontinuous phases. The structure of the confined colloids is investigated by means of grand canonical Monte Carlo simulations in thermodynamic conditions at which either a cluster crystal or a cylindrical phase is stable in bulk. We find that by tuning the size of the unit cell of these porous materials, numerous novel ordered microphases can be produced, including cluster crystals arranged into close packed and open lattices as well as nonparallel cylindrical phases.

The removal of toxic nitrophenols from the industrial wastewater is urgently needed from health, environmental and economic aspects. The present study deals with the synthesis of crosslinked vinyl polymer Poly(divinylbenzene) (poly(DVB)) through free radical polymerization technique using AIBN as initiator and acetonitrile as solvent. The prepared polymer was used as a support for silver nanoparticles via chemical reduction of silver nitrate on the polymer network.

Prussian blue analogs (PBAs), as a classical kind of microporous materials, have attracted substantial interests considering their well-defined framework structures, unique physicochemical properties and low cost. However, PBAs typically adopt cubic structure that features small pore size and low specific surface area, which greatly limits their practical applications in various fields ranging from gas adsorption/separation to energy conversion/storage and biomedical treatments. Here we report the facile and general synthesis of unconventional hexagonal open PBA structures.

Ln-MOFs, composed of lanthanide ions and functional organic ligands, are porous materials with tunable structures and unique luminescent properties. However, the interplay between ligand AIE properties and the framework's "antenna effect" on MOF morphology is understudied. Here, Tb-D-Cam-TPTB was synthesized via solvothermal method using TPTB (persulfurated arene) as the primary ligand, D-Cam as the auxiliary ligand, and Tb3+ as the metal ion.

The release of microcystin (MCs) in aquatic ecosystems poses a substantial risk to the safety of irrigation and drinking water. In view of the challenges associated with monitoring MCs in water bodies, given their low concentration levels (μg/L to ng/L) and the presence of diverse matrix interferences, there is an urgent need to develop an efficient, cost-effective and selective enrichment technique for MCs prior to its quantification. In this work, a gold nanoparticles (AuNPs)-functionalized zwitterionic polymer monolith was described and further applied for the affinity enrichment of MCs.
