    • Interaction between the oxidized carbazole branches and the porphyrin core (in the P1-P6 compounds, the carbazoles, or at least some of them, are the first to be oxidized, so the interaction involves porphyrin core and oxidized branches) is expected to move porphyrin-centered oxidation to more positive potentials. Such an interaction is depending on the spacer between core and branching subunits.

    • We would like to thank one of the reviewer for suggesting us to use the "Lippert-Malaga" plots.

    • note
    • In principle, most of the experimental results that lead to a TICT assignment for the room-temperature emission of A1-A6 could also support a twisted ground state that becomes more planar upon CT excitation. However such an alternative interpretation can hardly justify the complete charge-transfer calculated from the Lippert-Mataga plot (in fact, assuming a charge separation over a distance of 3 A in the excited emitting state and a variation in the dipole moment between ground and emitting states of ca. 12 D (from the slope of the Lippert plot), about 1 electron is calculated to be involved in the CT process, i.e., complete charge transfer) and, even more important, cannot explain the 77 K luminescence properties of A3 (see later in the main text).
