Description Template-based approaches involving the co-operative
organization of organic-inorganic assemblies as intermediates
are emerging as a promising conceptual basis
for future developments of porous inorganic materials.
This field has been fuelled by new synthetic strategies
such as “supramolecular templating” that have enabled
precise engineering of pore size, shape and connectivity
on the mesoscopic scale [1]. Randomly oriented
layers of AlPO4 were synthesized and used as chemical
sensors and low dielectric constant materials [2]
earlier, but now, attention is being directed towards the
formation of highly oriented films of metallic phosphates
[3]. Development of AlPO4 based materials, in
particular, has extended the compositional and structural
diversity of the molecular sieves. Anisotropy induced
by biomolecules leads to orientation and many
exotic properties associated with the hierarchical structures
and make them suitable for a range of applications
including catalysis, ion-exchange separation, nuclear
medicine and optics [4]. Though the synthetic templates
namely latex fibers, polyurethane foams, starch
gels, carbon nanotubes and organic molecules with long
chains are being routinely employed for the synthesis
of hierarchical inorganic frameworks [5], mineralization
of biomolecular templates like tobacco mosaic
virus (TMV) is a relatively new concept [6]. It leads
to the formation of porous structures at nanolength
scales that are strictly controlled by the presence of
protein superstructures. Moreover, these biomolecular
templates offer unusual symmetry and mesoscale ordering
in the porous structures. Abundance and stability
of the protein molecules present in tobacco leaves
and their tendency to undergo self assembly has motivated
us to use it directly as templates to synthesize
self supporting hybrid films at liquid-air interface.
