25. -1 is related to the energy difference between the preferences of the cyclophane for the TTF station over the DNP station, which leads to ratios of 96:4-99.3:0.7; see: S. Kang, S. A. Vignon, H.-R. Tseng; J. F. Stoddart, Chem. Eur. J. 2004, 10, 2555-2564. In order to reflect these thermodynamic differences, we have introduced the term ground-state coconformation for the translational isomer with the cyclophane residing at the TTF station and metastable state co-conformation when it is at the DNP station; see references 8c and 9 for more details.
