Diazirine 63 was photolyzed in various solvents and within CyDs. The solution results are summarized in Table 8. The conventional solvents were used to gauge whatever effects the CyD hosts had on carbene 64. Hydrocarbon solvents, like pentane ( -C5Hi2) and cyclohexane (c-C6H12), were used to mimic the inner cavities of CyDs, which are also nonpolar, hydrophobic environments. Tetrahydrofuran (THF) was employed because the cyclic ether resembles the D-Glcp monomer units of the CyDs. Moreover, since CyDs also possess many hydroxyl (O-H) groups, it seemed appropriate to perform control experiments in alcoholic solutions of diazirine 63. Finally, chloroform (CHC13) was used to assess the spin-state of carbene 64.
