Abstract

A cage molecule incorporating three electron donating monopyrrolotetrathiafulvalene units was synthesised to host electron accepting [60]fullerenes. Formation of a strong 1:1 donor-acceptor (D-A) complex C₆₀⊂1 was confirmed by solid state X-ray analysis as well as ¹H NMR and absorption spectroscopic analyses of the arising charge-transfer (CT) band (λ = 735 nm, ϵ ≈ 840 M^-1 cm^-1). Inserting Li⁺ inside the [60]fullerene increased the binding 28-fold (K_a = 3.7 × 10⁶ M^-1) and a large bathochromic shift of the CT band to the near infrared (NIR) region (λ = 1104 nm, ϵ ≈ 4800 M^-1 cm^-1) was observed.
