In recent years, the study of the electroactive properties of heterocyclic conducting polymers containing nitrogen atoms like polyaniline, polypyrrole, polycarbazole and their substituted derivatives has attracted considerable interest due to their wide fundamental interest and potential industrial applications. Due to its regular nanostructured pores, MCM-41 has attracted considerable interest, for adsorption of various gases and vapors. Other interesting physical properties of these materials include a highly specific surface up to 1000 m2/g, a specific pore volume up to 1.3 ml/g, and a high thermal stability; all of these make it suitable for many applications, [1]. Polyindole (PInd), is an electro active polymer which can be obtained either by anodic or by chemical oxidation of indole, C8NH7. PInd films have good thermal stability, high-redox activity and stability, slow degradation rate in comparison with PANI and PPy. This polymer and its derivatives appear to be good candidates for applications in various domains like electronics, electrocatalysis and pharmacology, [2]. In this work we study the Indole adsorption onto Al-MCM-41 and its in situ polymerization in order to obtain a nano-composite Polyindole/Al-MCM-41 (PInd/Al-MCM-41).
