BİFENOKSİ SÜBSTİTÜE YENİ FTALOSİYANİNLERİN SENTEZİ VE KARAKTERİZASYONU

Abstract

Yeni mono sübstitüe ftalonitril türevi 4-bisfenoksiftalonitril (3) K2CO3 varlığında ve kuru DMF? de 2,2? bifenol ve 4-nitro ftalonitrilin nükleofilik yer değiştirme reaksiyonu ile hazırlandı. Metalli ftalosiyaninler (4,5,6), (3) maddesinin [Co(Ac)2.4H2O, Cu(Ac)2.H2O, Zn(Ac)2.2H2O,] tuzları ile DMF?li ortamda reaksiyona sokularak elde edildi. (3) maddesinin, Ni(Ac)2.4H2O metal tuzu ile gerçekleştirilen reaksiyon sonucu ise, saf ve yapısı aydınlatılabilen ftalosiyanin kompleksi elde edilemedi. Ayrıca (3) maddesi, DBU katalizörü ilavesiyle argon atmosferinde metalsiz ftalosiyanin elde edildi (7). Yeni sentezlenmiş bileşiklerin yapıları IR, UV/Vis, 1H-NMR spektroskopileri ve MALDI-TOF kütle spektrometrisi ile karakterize edildi. Anahtar Kelimeler : Ftalosiyanin, top tipi ftalosiyanin, ftalonitril

A new mono substituted phthalonitrile derivative 4-bisphenoxyphthalonitrile (3) was prepared by a nucleophilic reaction of 4-nitrophthalonitrile with 2,2? biphenol in dry DMF in the presence of K2CO3. The metallophthalocyanines (4,5,6) were prepared by the reaction of a dinitrile derivative (3) material [Co(Ac)2.4H2O, Cu(Ac)2.H2O, Zn(Ac)2.2H2O,] by reacting with salts in the medium was obtained DMF. (3) material, Ni(Ac)2.4H2O as a result of reaction with the metal salt, which may be pure and structure elucidation of phthalocyanine complexes could not be obtained. In addition, (3) material, the addition of DBU catalyst metal-free phthalocyanine was obtained in an argon atmosphere (7). The structures of the newly synthesized compounds have been confirmed and characterized by FT-IR, UV/VIS, 1H-NMR and MALDI-TOF mass spectrometry.
