Fig. 2. MALDI-TOF MS (TCNQ, CHCl3) for 1 : 1 mixtures of 1 and (a) C60 and (b) C70 (insets show comparison of measured and simulated isotope patterns); UV/Vis titration experiments for complex formation between 1 and (c) C60 (black 1, purple C60, dotted red 1 + C60, red C60⊂1 derived from global fit to 1 : 1 model, inset shows fit to 1 : 1 model at λ = 329 nm) and (d) C70 (black 1, brown C70, dotted blue 1 + C70, blue C70⊂1 derived from global fit to 1 : 1 model, inset shows fit to 1 : 1 model at λ = 379 nm).
