Similar alkane and cycloalkane solvents should display similar properties yet we have found that the UV-VIS spectra can vary with just a small change in the number of carbons. For select cycloalkanes compared to straight chain alkanes we find an enhanced solubility and under some conditions the formation of solvates where the fullerene molecules are surrounded by the cycloalkane molecules and exhibit some stability. Cyclohexane, cis-decalin and trans-decalin solutions were prepared for this series of experiments. At times these solvates from a separate phase from the solvents and can be separated by filtration. UV-VIS spectra of some of the solvates were obtained and were different from more typical fullerene solutions. The appearance of the solvates depended on how the solutions were prepared.
