Dinaphthoporphycenes: Synthesis and Nonlinear Optical Studies
摘要:
Naphthobipyrrole-derived porphycenes are synthesized for the first time via McMurry coupling of the beta-alkylated 2,9-diformylnaphthobipyrrole derivatives, which in turn were prepared easily from 2,3-naphthalene bishydrazine in four steps. Insertion of nickel into the porphycene core results in transformation of the rectangular N4-core into a square type geometry owing to the fusion of naphthalene moiety onto the bipyrrole entities. These porphycenes show large, intensity dependent three-photon absorption.

Using naphthobipyrrole as a functional building block, a new expanded porphyrin, naphthoisoamethyrin, was prepared in 85% yield under acid-catalyzed [4 + 2] MacDonald coupling conditions. Treatment of naphthoisoamethyrin with the nonaqueous uranyl silylamide salt [UO2[N(SiMe3)2]2·2THF] yielded the corresponding uranylcomplex. Upon metalation, naphthoisoamethyrin undergoes a two-electron oxidation
