Naphthalocyanine is a derivative of phthalocyanine used as a component in the development of IBM's single-molecule logic switch.[1]

It was used to show the first images of charge distribution over a single molecule in November 2011.[2][3]

Its derivatives may also have uses in photodynamic cancer treatment.[4]
