Pyridyl acrylonitrile without traditional auxiliary groups form stable organogels in ethanol. The addition of a second non-gelating cyanostilbene component results in a more stable two-component gel. Single crystal X-ray data reveal the influence of C-H⋅ ⋅ ⋅N, C-H⋅ ⋅ ⋅π, and π-π interactions in the formation of organogels. The morphology of the xerogels was studied by using SEM, which showed the self-assembly of molecules to fibers and sheet-like structures, and phase differences upon the gel formation and the structural phase characterization was measured using powder XRD. Exposure of the organogels to acidic (TFA) vapors results in distinct color changes and loss of gelation properties, thus highlighting the potential of these gels in sensing. The results represent a rare example of two-component organogels using two different cyanostilbene units and show that functional two-component organogels can be formed by utilizing the synergistic effects of the individual components.

含有氰基苯乙烯的一组分和二组分有机胶体，无任何辅助取代基。

没有传统辅助基团的吡啶基丙烯腈在乙醇中形成稳定的有机凝胶。加入第二种非胶凝氰基二苯乙烯组分会产生更稳定的双组分凝胶。单晶X射线数据揭示了有机凝胶形成过程中CH⋅·⋅·N，CH⋅·⋅·π和π-π相互作用的影响。用SEM研究了干凝胶的形态，其显示了分子自组装成纤维和片状结构，并使用粉末XRD测量了凝胶形成时的相差和结构相表征。有机凝胶暴露于酸性（TFA）蒸汽中会导致明显的颜色变化和凝胶化特性的损失，因此突出了这些凝胶在传感中的潜力。
