A bis-crown ether-oxoporphyrinogen was newly synthesized and self-assembled concurrently with C₆₀ alkyl ammonium cations at the crown ether sites and F⁻ anions (through hydrogen bonding) at the oxoporphyrinogen core. Ultrafast photoinduced charge transfer processes within the donor–acceptor conjugate were promoted by fluoride ion binding and this was established using various spectroscopic methods and transient absorption studies.

自组装的C ₆₀烷基阳离子结合的双冠醚氧卟啉原超分子中的氟离子结合促进光诱导的电荷分离

A双-冠醚-oxoporphyrinogen是新合成的，并以C同时自组装₆₀在冠醚位点和F烷基铵阳离子^-在oxoporphyrinogen芯阴离子（通过氢键）。氟化物离子的结合促进了供体-受体结合物中超快光诱导的电荷转移过程，这是通过各种光谱方法和瞬态吸收研究确定的。
