    • (a) X-ray data were obtained for 4a but were not of sufficient quality for full analysis. The conclusions made for the structure of 5b are the same for this compound. The data can be found in the Supporting Information, (b) While this paper was being submitted, another related structure, 5,17- bis(diphenylphosphinoyl)-25,26,27,28-tetrapropoxycalix[4]arene, has been reported. The structure resembles that of our own structures. See: Jeunesse, C.; Matt, D.; Jones, P. G.; Thoennessen, H. Acta Crystallogr. 2003, E59, 428.

    • 3. This comparison is good taking into account the packing effect, which does not preclude an unavoidable void in the lattice. No solvent molecule was found as crystallizing molecule. By using the volume ratio, any systematic error caused by the method is minimized.

    • 1H NMR spectra where no free COD and 1-hexene are observed. This result indicates that these ligands undergo chemical exchange in solution. In 14 and 15, such exchange also occurs, but at 77 K, the process is stopped and the solutions are composed of a mixture of the starting material in deceasing amount according to the increase in [1-hexene] and the nonluminescent species.
