Abstract

ABSTRACT: Paramagnetic metal complexes with tetrathiafulvalene moieties in its ligands, [Cu II (EDT-sae-TTF)2 ] (1 ) and two new derivatives were investigated towards the potential application to the organic thin film transistor (OTFT) with magnetic field responsiveness. The complex1 and its benzene substituted derivative, [Cu II (Bz-sae-TTF)2 ] (2 ), gave semiconducting radical cation salts with fairly good electrical conductivity. A field effect transistor (FET) device fabricated with the spin-coated film of1 was operative, but its performance was quite low. Atomic force microscopy (AFM) images revealed that the spin-coated film of1 consists of very small grains with the size of about 10 nm, which can be responsible for the low device performance.
