The synthesis of tetramethyl-tetraphthalimidomethyl-phthalocyaninato zinc(II) (6) and tetramethyl-tetraaminomethyl-phthalocyaninato zinc(II) (7) is described.
Alkyl 4,5-dibromo-2-methylbenzoate derivatives 16–18 were synthesized from 1,2-dibromo-4-alkoxymethyl-5-methylbenzene 2–4 in the presence of catalytic amounts of NBS as a radical initiator. Only primary ether derivatives rendered the corresponding esters.
The synthesis of a novel ligand, in which four terpyridine groups are directly connected to a zinc (II) phthalocyanine unit, is described. Preliminary absorption, electrochemical, and fluorescence results are indicative of strong electronic coupling among the metal centers. (C) 1998 Elsevier Science Ltd. All rights reserved.
