Abstract

Abstract: By reacting equimolar amount of trimethylindium with various N ‐alkoxy carboxamidate type‐ligands in a single step reaction, new series of indium complexes (1‐3 ), [In(CH3 )2 (L)]2 (L 1 H= N ‐methoxypropionamide (mpaH), L 2 H= N ‐ethoxy‐2‐methyl propanamide (empaH), L 3 H= N ‐ethoxy‐2, 2‐dimethyl propanamide (edpaH)), were successfully synthesized. All complexes were fully characterized by FTIR and NMR spectroscopy along with elemental and thermogravimetric (TG) analyses. While complex1 and2 were solid in room temperature, complex3 which relatively bulkier ligand L 3 H was introduced was in liquid state. Among them, complex1 was structurally characterized by single crystal X‐ray diffraction. Complex1 existed in a tetragonal I 4(1) /a space group that consist of a pair enantiomers. A sharp weight loss between 130 °C and 230 °C in a single step in TGA for all complexes showed outstanding volatility properties with lowest residual mass of 10% which are a crucial factor in thin film industry. Abstract : Three new indium complexes have been designed for thin film transistor applications using N ‐alkoxy carboxamide type ligand. Synthesized compounds were fully characterized by NMR, FT‐IR, elemental analysis and single‐crystal X‐ray diffraction studies. Proper volatility test was performed using thermogravimetric analysis and all compounds showed similar property by showing a sharp single stepwise weight loss pattern with low final residual mass leftovers. *Indium‐complex, N‐alkoxy carboxamide ligand
