Syntes av Zink (ditiolen) koordinationsnanoskikt och transmetallation med metallsalter (Swedish)
Abstract [en]

Metal-ligand coordination nanosheets have shown both good and novel electrical properties and have sparked research in to organic metals. A dithiolene complex based nanosheet can be produced using benzene hexathiol (BHT) as ligand and have, for example, shown high conductance when using copper as a metal centre. (1)  Zinc coordinates relatively weakly to BHT and in a square planar composition, making it a prime candidate for synthesizing a nanosheet which can be transmetalated. This can be used to generate novel electrical materials within a single lattice framework. In this study, a robust bottom up method is set up for producing large domain zinc(dithiolene) coordination nanosheets (ZnDT). Nickel, copper, and cobalt metal salts are then used to transmetalate the nanosheets. Showing the possibility of using ZnDT as a template to produce a single lattice framework dithiolene nanosheets consisting of different metal centres.

Abstract [sv]

Nanomaterial baserade på metall-ligand koordinationskemi har visat både goda och nya elektriska egenskaper, vilket har ökat forskningen inom organiska metaller. Ditiolenbaserade nanomaterial där benzen hexatiol (BHT) används som ligand har, till exempel, visat hög konduktans när koppar har använts som metallcentra.(1) Zink koordinerar till BHT med relativt svaga bindningar i plankvadratisk geometri, vilket gör det till en god kandidat för att syntetisera ett nanomaterial som kan transmetalleras. Denna egenskap kan användas för att skapa nya elektriska material inom samma kristallstruktur. I denna studien framställs en robust botten upp metod för att syntetisera zink(ditiolen) koordinationsnanomaterial (ZnDT). Samt undersökandet av transmetallation med nickel, koppar och kobolt metallsalter. Vilket visar möjligheten i att använda ZnDT som en mall för att producera ditiolenbaserade nanomaterial bestående av metallcentra med olika metaller inom samma kristallstruktur.
