“…Only a small catalyst loading was needed because of the high catalytic activity of aminopropyl groups. [93] Derivatives of POSS, including catalytic moieties also were prepared and employed as a catalyst. A rigid POSS-based porous cationic framework was fabricated from octakis(chloromethyl) silsesquioxane and rigid n-heterocyclic cross-linkers.…”

Silsesquioxanes (SSQs), with the general formula, (RSiO1.5)n—where R stands for an organic group, such as alkyl, aryl, alkoxy, or H—are a type of molecular‐level organic/inorganic hybrid silica‐based material. These materials contain reactive or nonreactive organic moieties as well as inorganic Si–O–Si frameworks. In the past few years, extensive efforts have been made using SSQs to construct multifunctional nanocomposites with suitable properties for a range of applications. In this review, the recent various applications of SSQ‐containing hybrid materials are discussed, in addition to updates of the nanocomposite applications. Various physical structures and chemical reactions in SSQ‐based hybrid nanomaterials are emphasized with regard to applications in the field of polymer nanocomposites, catalysts, adsorption, sensors, and biomedicine. This review focuses on results reported in the recent five years (2013–2018).

“…Despite the availability of these methods, there remains enough scope for an efficient and reusable catalyst with high catalytic activity to achieve such systems. In our continuing effort toward the development of efficient and environmentally benign magnetic nanocatalysts, MNPs‐NHC 6 H 4 SO 3 H was prepared by a simple method as a highly efficient acid magnetic catalyst. In order to investigate the catalytic activity of this magnetic catalyst, one‐pot synthesis of 1,4‐diazepines containing the tetrazole ring via a four‐component reaction was performed under microwave irradiation (Scheme ).…”

In our continuing effort toward the development of efficient and environmentally benign magnetic nanocatalysts, [24][25][26][27] Figure S1. The XRD patterns indicate that the three products (Figure S1a-c) show similar diffraction peaks, indicating that the coating agent does not significantly affect the crystal structure of the magnetite nanoparticles.…”

MNPs‐NHC6H4SO3H as an efficient catalyst was prepared and characterized by X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), DLS dynamic light scattering (DLS), and thermogravimetric analysis (TGA) techniques. The catalytic activity of MNPs‐NHC6H4SO3H was investigated in the synthesis of 1,4‐diazepines containing the tetrazole ring via a four‐component reaction under microwave irradiation. The heterogeneous catalyst could be recovered easily and reused six times without significant loss of its catalytic activity. The present work demonstrates the advantages of microwave irradiation‐assisted heterogeneous catalysis in the synthesis of 1,4‐diazepines containing the tetrazole ring, compounds that generate great attention in many applications, particularly in medicinal chemistry and drug discovery.

A novel Fe 3 O 4 @SiO 2 @(CH 2 ) 3 N+Me 3 I 3 -magnetite nanoparticle was prepared and utilized in the synthetic conversion of aldehydes to imidazole derivatives in solvent-free conditions. These functionalized magnetic core-shell nanoparticles (MNPs) were characterized by Standard technique such as TEM, SEM, EDX, FT-IR, XRD, and VSM. The work up of reaction was very simple containing only a magnetic decantation. This novel catalyst could be separated easily and recycled several times without any significant decreasing of catalytic activity.
