The synthesis of a crystalline two-dimensional (2D) polymer linked by C-C bonds can be considered as one of the holy grails of synthetic chemistry. Possible routes may involve interface-confined polymerization at air-water or solid-solid interfaces or sterically constrained polymerization of prepacked crystalline monomers.

Abstract This chapter introduces a general protocol to transfer metal ions from aqueous solution to an organic medium, which involves mixing the aqueous solution of metal ions with an ethanolic solution of dodecylamine (DDA), and extracting the coordinating compounds formed between metal ions and DDA into toluene. This protocol could be applied toward transferring a wide variety of transition m...

There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy, and medicine. Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. In this work, we describe a cost effective and environment friendly technique for...

in this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (ii) sulfate as metal precursor and polyvinylpyrrolidone k-30 (pvp k-30) as surfactant agent. the reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. characterization o...

Erythropoietin, commonly known as EPO, is a glycoprotein hormone that stimulates the production of red blood cells. Recombinant EPO has been described as "arguably the most successful drug spawned by the revolution in recombinant DNA technology". Recently, the EPO glycoprotein molecule has re-emerged as a major target of synthetic organic chemistry. In this article I will give an account of an ...

They are therefore attractive synthetic targets for organic and medicinal chemist. The current review article mainly covers the multicomponent green chemistry approaches for the synthesis of 1,5-benzo...

Hydrogel electrolytes, which feature intriguing characteristics of being soft and wet, accompanied with high solubility zinc salts, are especially advantageous for fabricating flexible Zn-based batteries. Furthermore, the abundant tunable chemistries hydrogels offer opportunities to bestow novel affiliated functionalities, such as super toughness, extreme temperature tolerance, stimuli-responsi...

objective: dendrimers are three-dimensional nanostructures that have numerous applications in medicine, including drug delivery and imaging. although anionic dendrimer polyethylene glycol–citrate has a high potential to increase solubility of water-insoluble drugs and drug delivery, its multi-step synthesis procedure is time consuming. in addition, toxic substances such as dichloromethane are u...

Introduction In recent years, a new approach called “Green Chemistry” emerged in the field of organic chemistry, to prevent or minimize contamination from the laboratory bench up to industrial production. It purpose is to avoid residue formation, saving time and costs. One of the strategies proposed for the existing products involves designing alternative synthesis steps that do not use toxic s...

the heterocyclic compounds have a great importance in medicinal chemistry. one of the most important heterocycles in medicinal chemistry are quinazolines possessing wide spectrum of biological properties like antibacterial, antifungal, anticonvulsant, anti-inflammatory, anti-hiv, anticancer and analgesic activities. this skeleton is an important pharmacophore considered as a privileged structur...
