&lt;div&gt;There is a growing need to to develop sustainable alternatives to the synthesis of materials through the use of renewable chemical resources. Here we report the utilization of plant-derived oleyl amine surfactants as porogens for the synthesis of mesostructured forms of silica in place of the usual petroleum – or animal- derived surfactants. Oleyl–NH2 and oleyl–NH(CH2)3NH2 derivatives are shown to be effective templating agents for the hydrogen bonded assembly of silica mesophases with well-expressed wormhole and lamellar framework structures. Owing to the presence of the cis double bond in the hydrophobic segment, cross-linking of surfactant micelles can be achieved with divinylbenzene. Intercalation of the cross-linked micelles in the pores of the as-made mesophases makes it possible to immobilize metal ions at the surfactant-silica interface through complexation by the amino head groups without the loss of surfactant to solution.&lt;/div&gt;
