Self-assembled organic homostructures with tunable optical waveguides fabricated via “cocrystal engineering”

Organic homostructures with tunable physiochemical properties were fabricated by simply changing the isomer molecules via the "cocrystal engineering" approach. The morphology of the cocrystals can be changed into rod-like or branched, with superior waveguide and multi-directional waveguide performance, respectively, which contributes to the realization of optical waveguide modules with integrated functions.
