    • This is because the large overlap between the fluorescence spectrum of fluorescein and the absorption spectrum of the open form of SP (MC) result in efficient photoinduced energy transfer and decrease in fluorescence from fluorescein and it is opposite when it comes to SP, see:

    • the fluorescence intensity at around 530 nm of the complex formed between 1 and 2 was reduced by ca. 57% after UV light irradiation for 5.0 min. This was comparable to the fluorescence reduction reported for the covalently linked SP-fluorescein dyad (see J. Org. Chem. 68 (2003) 5681). This also indicates the formation of the host-guest inclusion complex between 1 and 2.

    • This is simply due to the fact that the intermolecular energy transfer between the excited state of fluorescein and MC is fully responsible for the fluorescence modulation observed for the ensemble of 1 and 3; for the ensemble of 1 and 2, however, both the corresponding intramolecular and intermolecular energy transfer processes make contributions to the fluorescence modulation.
