    • Typical structure of (Eu)1 obtained from a molecular modeling simulation in a box of OPLS methanol using the CHARMM force field. In the simulation, the n-butoxypropyl moieties have been replaced by methyl groups. The hydrogen atoms have been removed for clarity. For the simulation the same procedure was followed as reported in: van Veggel, F. J. C. M.; Reinhoudt, D. N. Recl. Trav. Chim. Pays-Bas 1995, 114, 387.

    • In principle the quantum yields should have been measured against a few standards, including one that emits in the red. However, it is our experience that quantum yields determined for similar complexes against quinine sulfate, ruthenium trisbipyridine, and cresyl violet are the same within 5%.

    • 3+ luminescence (see e.g. ref 16), but the ligand only has absorption bands up to 300 nm. If the excitation wavelength is above 300 nm, then the sensitization pathway exclusively takes place via the coordinated antenna.

    • Singular value decomposition (SVD) of the data is readily achieved by microcomputers running an appropriate computer programm with an implemented SVD routine. For this work the Igor Pro package (Wavemetrics, Inc., Lake Oswego OR) was used.

    • note
    • 3+ is actually more cathodic due to the complexation of a trivalently negatively charged ligand. No data on the complexes are available but it is expected that still a driving force remains for the charge transfer.
