    • Absorption maxima are less sensitive to solvent polarity (Table 1 ). The ICT excited state is polar, with a large dipole moment due to a substantial charge redistribution, and is expected to be sensitive to solvent polarity. Direct transition from the ground state to the ICT state may be forbidden. The less sensitive absorption maxima to the solvent polarity suggest that the ICT state is derived following relaxation of the initially formed Franck-Condon excited state (ref 32a).

    • The ICT often produces PL quenching by charge separation after excitation, increasing the rates of the radiationless decay processes. Several mechanisms for the ICT-related quenching were suggested. See: (a) Schuddeboom, W.; Jonker, S. A.; Warman, J. M.; Leinhos, U.; Kühnle, W.; Zachariasse, K. A, J, Phys. Chem. 1992, 96, 10809.

    • In addition, PL quenching by specific solute-solvent interaction such as hydrogen bonding should be considered in water. The excitedstate complex via hydrogen bonding may activate radiationless depopulation channels, for example, energy dissipation through the vibrations connected with hydrogen bonding.

    • We observed a similar trend on the solvent dependence of the measured TPA cross section of the structure that contains two fragments of 8 held together via the [2.2]paracyclophane core: 1290 GM in toluene, 2180 GM in THF, 1300 GM in DMSO, and 370 GM in water.
