合成了包含三个给电子单吡咯四硫富瓦烯单元的笼状分子以作为受电子[60]富勒烯的主体。通过固态 X 射线分析以及 1H NMR 和对所产生的电荷转移 (CT) 带（λ = 735 nm，ε ≈ 840 M−1 cm−1）的吸收光谱分析，证实了强 1 : 1 供体 - 受体 (D–A) 复合物 C60⊂1 的形成。在[60]富勒烯内插入Li+使结合增加了28倍（Ka = 3.7 × 106 M−1），并且观察到CT带向近红外（NIR）区域（λ = 1104 nm，ε ≈ 4800 M−1 cm−1）发生大的红移。
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 (Ka = 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.
