“…[3][4][5][6][7][8][9][10][11][12] Among these, para,para'-functionalized oligophenylenes bearing various substituents have been found to self-assemble into well-defined, mutually aligned fiber-like nanostructures upon vapor deposition onto a freshly cleaved mica surface. 13 Changing the molecules' chain length and substitution pattern does not only have an effect on the electrical and optical properties on the molecular level, but also on the self-aggregation and the physical properties of the nanostructures. 14,15 However, this approach asks for oligomers of four or more aromatic units in order to have a vapor-pressure in the right regime to allow sublimation under ultra-high vacuum conditions (≤ 10 −7 mbar) whereas oligomers containing only three aryl units are usually too volatile under these conditions.…”

π-Conjugated rod-like molecules have proven to be powerful candidates for the generation of well-defined nanostructures with interesting optical and optoelectrical properties. Their synthesis, however, turns out to be rather complex in some cases. Here, we have optimized the synthesis of oligomers consisting of thiophene and phenylene groups with three or four aromatic units using a direct arylation approach, which allows us to use cheap starting materials and to minimize the number of reaction steps considerably.

Self‐Assembled Organic Microfibers for Nonlinear Optics

et al. 2013

While highly desired in integrated optical circuits, multiresponsive and tunable nonlinear optical (NLO) active 1D (sub)wavelength scale superstructures from organic materials are rarely reported due to the strong tendency of organic molecules to self-assembly in centrosymmetric modes. Here a solution-processed assembly approach is reported to generate non-centrosymmetric single-crystalline organic microfibers with a cumulative dipole moment for anisotropic combined second- and third-order NLO.
