In this article we present dual-component charge-transfer interaction (CT) induced organogel formation with bile acid anthracene conjugates as donors and 2,4,7-trinitrofluorenone (TNF) as the acceptor. The use of TNF (1) as a versatile electron acceptor in the formation of gels is demonstrated through the formation of gels with different steroidal groups on the anthracene moiety in a variety of solvents ranging from aromatic hydrocarbons to long chain alcohols. Thermal stability and variable temperature fluorescence experiments were performed on these CT gels. Dynamic rheological experiments conducted on these gels suggest that these are viscoelastic soft materials and with the gel strength can be modulated by varying the donor/acceptor ratios.
在本文中，我们提出了双组分电荷转移相互作用（CT）诱导的胆酸蒽衍生物作为给体和 2,4,7-三硝基芴酮（TNF）作为受体的有机凝胶形成。通过在各种溶剂中（从芳烃到长链醇）用蒽部分上具有不同甾体基团的 TNF（1）形成凝胶，证明了 TNF（1）作为凝胶形成中多功能电子受体的用途。对这些 CT 凝胶进行了热稳定性和变温荧光实验。对这些凝胶进行的动态流变实验表明，这些是粘弹性软材料，并且通过改变供体/受体比可以调节凝胶强度。
