a 1H NMR titration spectra of G1 (2.0 × 10−3 M, 600 MHz, D2O, 298 K) with (a) 0 equiv., (b) 0.25 equiv., (c) 0.5 equiv. of CB[8]. b ESI-HRMS spectrum of CB[8]·G12. UV-Visible absorption (c) and photoluminescence spectra (d) of G1 (2.0 × 10−5 M in H2O) with different amount of CB[8] (0~0.5 equiv.) at 298 K (λex = 420 nm). e ITC data for G1 with CB[8] in H2O ([G1] (syringe) = 2.0 × 10−3 M, [CB[8]] (cell) = 8.0 × 10−5 M, 298 K).
