THE SOLVATOCHROMISM OF C-60 AND ITS COLOR IN SOLUTION

This paper analyses the solvatochromism of C-60 in a wide range of ali phatic and aromatic solvents (nearly 50), as well as in the gas phase, on the basis of the spectral shift induced by the environment on thre e peaks in the UV/vis absorption spectrum of C-60 that are representat ive of the whole spectrum. Solvents are categorized by their solvent d ipolarity-polarizability (SPP) values. In order to analyze the potenti al involvement of C-60 in the formation of charge-transfer or hydrogen -bonding complexes, we studied its behavior in 11 monosubstituted benz ene solvents and as many alkanols.
