Pentacenes Exhibit Unsymmetrical Side

Synthetic strategy broadens the chemical repertoire of this electronically useful class of compounds
Department: Science & Technology
Keywords: pentacene, C-H activation

A synthetic strategy that produces previously rare unsymmetrical pentacene derivatives has been developed, broadening the chemical repertoire of this industrially useful class of compounds (Org. Lett., DOI: 10.1021/ol102349r). Pentacenes, a linear framework of five benzene rings, can be used to make a host of electronic materials, from organic semiconductors to solar cells. Until now, pentacenes have typically been symmetrical, . . .
