Convenient and Template-Free Route to One-Pot Green Synthesis of Polyrhodanine Core–Shell Nanoparticles

Abstract

In this publication, a copper acetate-mediated rhodanine polymerization reaction is examined. It is demonstrated that at room temperature, Cu(II) acetate complexes with rhodanine generate solid nanospheres, which, upon heating in a microwave, results in polyrhodanine core–shell nano- and microsphere particles. The structural analysis of the polyrhodanine nanosphere produced by this efficient microwave-initiated method was conducted by Fourier transform infrared spectroscopy, UV–vis spectroscopy, scanning electron microscopy, and transmission electron microscopy. In addition, it is verified that this template-free, efficient, and versatile synthesis of polyrhodanine nanospheres can also be accomplished by introducing a strong oxidant KMnO 4 as a cocatalyst with copper acetate without compromising the morphology of the resulting core–shell nanospheres. It is also demonstrated that the polyrhodanine nanospheres can be used to adsorb methyl orange dye, a known contaminant in industrial wastewater.

“…The key problem is to fabricate core–shell-encapsulated arrays for the quantitative release of diversiform odorous molecules. The capsules contain an aqueous core with odorous molecules and a PLGA protective shell .…”

Polyrhodanine-based nanomaterials for biomedical applications: A review

“…An interesting study reported that utilisation of copper acetate as an oxidising agent in synthesis of PR nano-/microspheres. In this direct one-pot and green approach, its polymerisation happened under mild conditions, based on microwave synthetic protocol, as well as a green solvent involved in this transformation, such as water or ethanol [ 17 ]. The oxidative oligo-/polymerisation process was initiated and led to the formation of a complex of copper (Cu) with rhodamine.…”

Fundamental Methods for the Phase Transfer of Nanoparticles

“…Our interest in the area of phase transfer is need based. In our laboratory, we have developed new methodologies for one pot creation of novel metal nanoparticles in organic and aqueous solvents [ 66 , 67 , 68 , 69 ]. In our ongoing projects, we have water-soluble nanoparticles, which we want to tailor with drug molecules.…”
