ΑΖΩΤΟΥΧΑ ΠΑΡΑΓΩΓΑ ΤΟΥ ΤΕΤΡΑΘΕΙΑΦΟΥΛΒΑΛΕΝΙΟΥ ΚΑΙ ΤΕΤΡΑΣΕΛΗΝΑΦΟΥΛΒΑΛΕΝΙΟΥ ΚΑΙ ΑΓΩΓΙΜΑ ΑΛΑΤΑ ΑΥΤΩΝ

SYMMETRICAL TETRATHIAFULVALENES AND TETRASELENAFULVALENES (Π- DONORS) CONTAINING NITROGEN ATOMS WERE SYNTHESIZED AND CHARACTERIZED BY ELEMENTAL ANALYSIS AND VARIOUS SPECTROSCOPIC TECHNIQUES. NITROGEN ATOMS HAVE BEEN INTRODUCED IN Π-DONORS MOLECULE IN THE FORM OF PYRAZINE, QUINOXALINE PARIDINOPYRAZINE AND PYRIDINE RINGS. SEVERAL OF THE CONDUCTIVE RADICAL SALTS OF THE SYNTHESIZED Π-DONORS WERE PREPARED BY ELECTROCRYSTALLIZATION OF THE DONOR IN THE PRESENCE OF BU4NX (WHEREX:ANION). SEVERAL OF THESE SALTS WERE STUDIED BY X-RAY CRYSTALLOGRAPHY AND U.V. VIS SPECTROSCOPY, IN EITHER REFLECTANCE OR ABSORPTION MODE. ELECTRICAL MEASUREMENTS ON THE CONDUCTIVE SALTS WERE ALSO PERFORMED. THE RESULTS OF THESE STUDIES HAVE SHOWN THAT ALL OF THESE EXAMINED SALTS ARE SEMICONDUCTORS MAINLY ANISOTROPIC, BUT SOME OF THEM BECOME ALMOST ISOTROPIC AT LOW TEMPERATURES.
