Molecular self-organization and self-assembly in supramolecular

structures is actually the basis of functional nanomaterial construc-

tion in a bottom-up strategy. The road from molecular to nano-

(micro-) scale devices depends both on the nature of its constituents

and on the interactions between them [1]. Hybrid organic-inorganic

materials produced by sol-gel processes are the subject of var-

ious investigations, offering an opportunity to obtain nanostruc-

tured materials initially from molecular [2] and more recently from

self-organized supramolecular [3] silsesquioxane systems. Of spe-

cial interest are the structure-directed function of hybrid materials and the control of their buildup by self-organization. Recently, the

possibility to create hybrid macrocyclic complexant membranes, selforganized in directional tubular superstructures at the nanometric

level, has been shown. Organogels resulting from multiple self-

assembly processes and acting as robust organic templates for the

tetraethoxysilane (TEOS) sol-gel process have been used for the syn-

thesis of different inorganic structures. Furthermore, unarguably,

fuel cells have the potential to become an important energy conver-

sion technology [4]. These materials reveal great potentialities from

the point of view of their chemical composition as well their organi-

zation for concerned applications [5].
