Rational understanding of the structural features involving different noncovalent interactions is necessary to design a liquid crystal (LC) or an organogelator. Herein, we report the effect of the number and positions of alkoxy chains on the self-assembly induced phys. properties of a few π-conjugated mols. For this purpose, we designed and synthesized three C3-sym. mols. based on oligo(p-phenylenevinylene), C3OPV1-3. The self-assembly properties of these mols. are studied in the solid and solution states. All of the three mols. follow the isodesmic self-assembly pathway. Upon cooling from isotropic melt, C3OPV1 having nine alkoxy chains (-OC12H25) formed a columnar phase with two-dimensional rectangular lattice and retained the LC phase even at room temperature Interestingly, when one of the -OC12H25 groups from each of the end benzene rings is knocked out, the resultant mol., C3OPV2 lost the LC property, however, transformed as a gelator in toluene and n-decane. Surprisingly, when the -OC12H25 group from the middle position is removed, the resultant mol. C3OPV3 failed to form either the LC or the gel phases.
