    • The same experiment was carried out for the reference donor-acceptor ensemble 1/2, obtaining similar results. The 1:1 stoichiometry of 1/2 and 3/2 was also confirmed by mass spectrometry. The spectra recorded from a 1:1 mixture of the two components of each complex display peaks at m/z = 2618 and 3351, respectively.

    • Closer inspection of Figure 8 reveals that simultaneous with the quenching of the ZnPc 1 emission at 704 nm, a new lower-energy emission develops, which is centered at 702 nm.

    • However, given the margin of error, it was very difficult to analyze the decays of the 3/2 ensemble. Still a double-exponential fitting provides the best results.

    • Although the intra-ensemble transduction of the excited-state energy must occur in the singlet excited states, our picosecond analysis was unsuccessful to confirm this. Our failure is mainly due to the similar singlet excited-state features of the two phthalocyanine building blocks.
