PORPHYRIN ARRAY COMPRISING BIS(IMIDAZOLYLPORPHYRIN METAL COMPLEX) LINKED BY ACETYLENE BOND, EXHIBITING HIGH TWO-PHOTON ABSORPTION CHARACTERISTIC AS CONSTITUENT UNIT AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a material in which the length of a molecule is simply controlled, impossible using a covalent bond, and an acceptor or a donor molecule is linked to the terminal of an array and which exhibits high two-photon absorption.;SOLUTION: The porphyrin array comprises a bis(imidazolylporphyrin metal complex) represented by general formula (1-1) [R₁ is a substituted or a nonsubstituted alkyl group or a substituted or a nonsubstituted aryl group; M₁ is a metal ion which becomes a central metal of a porphyrin ring and forms a coordinate bond with an imidazolyl group represented by Im; R₂ and R₃ are each a free base porphyrin, its metal complex residue, a cyclic diimide residue, a dialkylviologen residue, a benzoquinone residue, an N-methylpyrrolidine-fullerene derivative residue or a ferrocene residue; Im is an Im₁ or an Im₂ (R₈ is a methyl group or H); L₁ is (-C≡C)_m (m is an integer of 1-3); n is an integer of ≥1] as a constituent unit.;COPYRIGHT: (C)2004,JPO
