        Polymeric materials have been widely used in energy-related applications including fabrication of batteries and fuel cells, pressure retarded osmosis, gas separation and reverse electrodialysis processes. Despite these various versatility, their poor mechanical properties still remain as obstacles for applying to industrial levels. As a way of improving the mechanical properties, Tröger's Base (TB) which is a rigid, V-shaped, and bridged bicyclic amine have been recently introduced. In this work, polyimides incorporating TB units (PI-TBs) were synthesized in-situ polycondensation reaction using dimethoxymethane (DMM). PI-TB membranes were prepared and physicochemical characteristics including mechancial properties were investigated.
