Doubly and Triply Linked Porphyrin−Perylene Monoimides as Near IR Dyes with Large Dipole Moments and High Photostability

Abstract

Doubly and triply linked porphyrin-perylene monoimides 3 and 4, with extraordinary stability, large dipole moments, and strong near IR absorption, were prepared by means of one-pot oxidative cyclodehydrogenation promoted by FeCl(3).
