文摘

(1,2-Naphthalocyaninato)lutetium(III),bis(1,2-naphthalocyaninato)lutetium(III), andtris(1,2-naphthalocyaninato)dilutetium(III) have been synthesized in good yields. Thesecomplexes were characterized by UV-visible,¹HNMR, and mass spectroscopies and by electrochemical techniques.Bis(1,2-naphthalocyaninato)lutetium(III)iscompared to bis(2,3-naphthalocyaninato)lutetium(III):the good correspondance between the experimental dataand theoretical results obtained by others is emphasized in this work.Stacking one to three macrocyclic rings ispossible in the series of the 1,2-naphthalocyanine sandwich-likecomplexes with lutetium(III); as shown by UV-visible spectroelectrochemistry and voltammetry, this influences greatlythe -conjugated systems, modifyingspectacularly their spectroscopic and redox properties.
