Molecular precursor mediated selective synthesis of phase pure cubic InSe and hexagonal In₂Se₃ nanostructures: new anode materials for Li-ion batteries

Abstract

Indium selenides (InSe and In2Se3) have earned a special place among the 2D layered metal chalcogenides owing to their nontoxic nature and favourable carrier mobility. Additionally, they are also being...

Accessing copper selenide nanostructures through a 1D coordination polymer of copper(ii) with 4,4′-dipyridyldiselenide as a molecular precursor

“…However, they differ in coordinating ability, and thus can exert different effects on the phase, composition and morphology of nanostructures. 47 The crystal structure, morphology, homogeneity and optical band gap of the nanostructures were investigated by pXRD, EDS, SEM, and TEM techniques and solid-state diffuse reflectance spectroscopy (DRS).…”

Controlled synthesis of photoresponsive bismuthinite (Bi2S3) nanostructures mediated through a new 1D bismuth-pyrimidylthiolate coordination polymer as a molecular precursor

“…47 The probable reason for the blue shift of the band gaps may be lattice distortions, surface lattice defects, quantum confinement or the surface effect of the carriers. 48…”

Molecular precursor approach to develop catalytically relevant nanosized metals, palladium chalcogenides and ternary/quaternary metal chalcogenides

“…Many of these methods involve nucleophilic substitution reactions wherein the generation of the nucleophile (RENa or ArENa, where E = S, Se or Te) is followed by its treatment with an alkyl/aryl halide to get the anticipated chalcogenoether or dichalcogenide or any other organochalcogen compound. Further, these organochalcogen compounds or their metal derivatives have been evaluated for anticancer properties, 12,13 development of single source molecular precursors (SSMPs) for metal chalcogenides [14][15][16][17] or for developing catalytic systems, 16,17 etc. For instance, various alkyl and aryl based chalcogen ligands developed over a period have been employed as SSMPs for metal chalcogenide materials with different applicability.…”

“…For instance, various alkyl and aryl based chalcogen ligands developed over a period have been employed as SSMPs for metal chalcogenide materials with different applicability. [14][15][16][17] Similarly, various organoselenium compounds and their metal complexes with different functionalities have been adopted for catalytic applications. [18][19][20][21][22][23][24][25] The latter include Click chemistry derived organochalcogen ligands for transition metal catalysis, 18 organochalcogen ligands for oxidation of alcohols 19 and arylation of phenols, 20 organochalcogen complexes for homogeneous catalysis, [21][22][23][24] palladium(II) complexes as catalysts for Heck and Sonogashira C-C coupling reaction, 25 etc.…”
