A novel composition is provided. The composition is a tetrameric reaction product of heterocyclic 3-thiophenecarboxaldehyde and an aromatic compound, the reaction product being a calix[4]arene. In one embodiment, the present invention is a thiophene functionalized calixarene selected from the group consisting of C-thiopheneresorcin[4]arene and C-thiophenepyrogallol[4]arene. In another embodiment, the thiophene functionalized calixarene further comprises silver nanoparticles.
