High Quality Content by WIKIPEDIA articles! Texaphyrin is a sub-class of heterocyclic macrocycle molecules known as porphyrins. The molecule was invented by University of Texas at Austin professor Jonathan Sessler. The name texaphryin arose because some of the molecules have a shape that can superimpose onto the points of the star featured on the state flag of Texas. Texaphyrins were nominated as the "State Molecule of Texas", but the buckyball was chosen instead.
