The phase structures of hydrogen-bonded benzene-1,3,5-tricarboxamide (BTA) derivatives in divinylbenzene (DVB) solutions were examined together with the template effects these during photopolymerization to make nanoporous polymers. BTA linear or branched alkyl chains found form supramolecular chains, solid crystalline nanofibers, mesophase aggregates DVB. These self-assembled caused DVB/BTA molecular composites adopt viscous liquid, nematic columnar liquid crystal, physical gel states. DVB homogeneous mixtures containing resulted macro-phase separation photo-cross-linked and derivatives. In contrast, nanofiber dispersed functioned as templates produce polymers after removal A mesomorphic mixture exhibiting a structural transition from crystal heterogeneous state enabled preparation uniaxially aligned Horizontally- vertically films synthesized through shear-induced electric-field-induced alignment phase. use additives provides potential approach controlling nanostructures improving optical electrical properties functionalities conventional polymeric materials composites.
