Zn-complex based on oxadiazole/carbazole structure: Synthesis, optical and electric properties

Abstract A mononuclear Zn(II) complex containing two carbazole/oxadiazole moieties, Zn(OC) 2 , was synthesized and characterized by means of elemental and thermal analyses and infrared spectroscopy. Current–voltage measurements of Ag/Zn(OC) 2 /p-Si and Ag/Zn(OC) 2 /n-Si heterostructures have been performed and compared to that of reference structures with the same metal contacts but without the insertion of the Zn(OC) 2 layer. Good rectification behavior has been observed for both hetero-diodes, independent of the silicon substrate doping type, confirming that the metal–organic layer can act both as electron or hole-conductor. Zn(OC) 2 complex displayed blue photo-luminescence in solution and in film.
