A new material, Leu(CH3)4-TCNQ, has been successfully synthesized from Tetracyanoquinondimethane (TCNQ) and amino acid ester, N,N,N-Trimethyl-L-Leucine Methyl ester ((Leu(CH3)4+). This material was characterized by modern physicochemical methods such as: X-ray diffraction technique (XRD), Raman, Infrared (FT-IR) and UV-Vis spectroscopy and voltammetric technique. This result will offering a new direction for the synthesis of new materials from TCNQ and other amino acids.
