Thin film electronics have gained interest among researchers due to its versatile synthesis,electronics and ease of device fabrications.Graphene,a prototypical example ofπ-conjugated all carbon 2D nanosheet,has opened the broad window of research due to rich physics from higher carrier mobility based on Dirac cone band dispersion.The exploitation of easy coordination chemistry,a powerful tool for varied metal and ligand combinations,in synthesizing 2D polymer is substantially a new bottom-up approach for material synthesis,unlike other top-down approaches.Hence,proper ligand design and metal selections are key aspects in functionalisation for properties like spin frustration,photochromism,magnetism,conductivity,photo-electric conversion,etc.Our research includes a novel synthetic strategy using liquid-liquid and gas-liquid interfacial synthesis forming flat layered?-conjugated bis(dithiolato)metal(MDT)coordination nanosheet(CONASH).C3 symmetric ligands such as benzene hexathiol(BHT)or triaminobenzene trithiol are non-innocent ligands,hence,the synthesis conditions are modified depending on the reduction potential of the d8 metal ions(like M=Ni,Pd,Pt)forming hexagonal symmetric MDT CONASHs as shown in Fig.1.The nanosheets are redox active,as a result,post modification of the sheets by chemical oxidation to change in electronic conductivity via changing the Fermi level are their important aspects as for the band structure studies are concerned.Free-standing stacked,and as thin as mono layer films were synthetically realized and characterized by different microscopic techniques namely AFM,SEM,TEM,etc.The composition of the sheets were studied by X-ray photo electron(XP)and infrared(IR)spectroscopic techniques.
