Near-infrared absorption of π-stacking columns composed of trioxotriangulene neutral radicals

Organic electronics: strong near-infrared light absorption with radical columns Near-infrared light absorption is enhanced by trioxotriangulene radicals that self-assemble into one-dimensional columns. Organic materials are attractive candidates for solar cells as they are inexpensive and have stron...
