Synthesis of Indium Complexes for Thin Film Transistor Applications Bearing N-Alkoxy Carboxamide Ligands

摘要

abstract_textpBy 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) ((LH)-H-1= N-methoxypropionamide (mpaH), (LH)-H-2=N-ethoxy-2-methyl propanamide (empaH), (LH)-H-3=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 complex 1 and 2 were solid in room temperature, complex 3 which relatively bulkier ligand (LH)-H-3 was introduced was in liquid state. Among them, complex 1 was structurally characterized by single crystal X-ray diffraction. Complex 1 existed in a tetragonal I4(1)/a space group that consist of a pair enantiomers. A sharp weight loss between 130 degrees C and 230 degrees 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./p/abstract_text
