Luminescence and anti‐aggregative properties of polyoxyethylene‐substituted phthalocyanine complexes
Source abstract
Abstract
A water‐soluble phthalocyanine derivative with 16 poly‐oxyethylene side chains which effectively prevent aggregation is reported. The first demonstration of luminescence in a water‐soluble, non‐ionic phthalocyanine in aqueous solution is discussed an important results from the development of effective manomeric dyes for use in phototherapy.
