Naphthalocyanine

Naphthalocyanine is a cross-shaped organic molecule consisting of 48 carbon, 8 nitrogen and 26 hydrogen atoms, it is a derivative of phthalocyanine. IBM Research labs used it for developing single-molecule logic switches[1] and visualizing charge distribution in a single molecule.[2][3]
