Optical Limiting Properties of Fullerene Biindene Adduct

We report the optical limiting (OL) properties of a new Diels-Alder mono-adduct of C60 with 1,1′-biindene. This Ceo derivative shows excellent OL properties to picosecond 532 nm laser pulses, which are almost the same as Ceo in toluene solution. Owing to its good stability and excellent solubility i
