Development of high-performing catalytic materials for selective and mild chemical transformations through adhering to the principles sustainability remains a central focus in modern chemistry. Herein, we report template-free assembly thermochemically robust covalent organic polymer (COP: 1) from 2,2′-bipyridine-5,5′-dicarbonyl dichloride 2,4,6-tris(4-aminophenyl)triazine as [2 + 3] structural motifs. The two-dimensional (2D) layered architecture contains carboxamide functionality, delocalized π-cloud, free pyridyl-N site-decked pores. Such trifunctionalization benefits this polymeric network exhibiting tandem alcohol oxidation-Knoevenagel condensation. In contrast common metal-based catalysts, 1 represents one kind metal-free oxidation reaction via extended π-cloud delocalization-mediated radical pathway, comprehensively supported diverse control experiments. addition reasonable recyclability broad substrate scope, condition underscores its applicability benign synthesis valuable product benzylidene malononitrile.

Exceptional category of alloys comprising five or more alloying metals in structures are referred as high entropy alloys. Uniqueness these have been observed due to the combination superior mechanical, thermal, conducting, anticorrosion, and other physical properties. Unlike traditional metallic (two metals), varying elemental compositions led limitless potential possibilities. Recent research has unveiled an important opportunity for based nanostructures like nanoparticles nanocomposites. This state-of-the-art review is basically intended highlight design essential structure, property, applied aspects alloy nanostructures. Consequently, various notable combinations with carbon (graphene, nanotube) inorganic surveyed. In this context, several nanocomposite designs reported using efficient techniques thermal shock, flame spray pyrolysis, plasma spark sintering, mechanical milling, alloying, electrochemical, solution name a few.
