In the presented study, the synthesis and full characterization of four different new diamine and polyimides derived from amino acids, including isoleucine (Ile), valine (Val), methionine (Met), phenylalanine (Phe) and benzimidazole fractions in the structure of pendant group is presented. The polymerization reactions of these monomers provided a series of new optically active polyimides (PIs) with inherent viscosities in the range of 0.68-0.98 dL g 21 . The obtained polymers were characterized by Fouriertransform infrared spectroscopy, specific rotation measurements, and the representative of them by proton nuclear magnetic resonance, gel permeation chromatography and elemental analysis techniques. The new diamine monomer containing L-isoleucine is employed as a key monomer for the sol-gel fabrication of a series of PI/titania nanohybrid films with various titania percentages. The special design of diamine monomer containing bulky pendant group increased the flexibility of resulted PIs. On the other hand, the ability to construct strong organic/inorganic H-bond lattice has led to the effective surrounding of titania by PI grounds and thus the well-dispersed quite spherical NPs were created via a sol-gel procedure.
