In-plane hierarchical assembly of two-dimensional molecular crystals toward on-chip multimode optical waveguides.

ABSTRACT: Two-dimensional (2D) organic lateral heterostructures (OLHs) integrating two or more components have important potential applications in optoelectronics. However, the controlled synthesis of 2D OLHs with in-plane tunable emission remains a great challenge owing to the difficulty in the sequential integration of multiple components. Here, a cascaded strategy is demonstrated for the hierarchical assembly of OLHs with in-plane multicolor emission, from red-blue and red-green to lateral red-green-blue (RGB), with a lateral size of ~15 micrometers. The tunable regions of 2D OLHs are realized by synergistic effects of the molecular doping method and the photo-induced oxidation route during the epitaxial growth process. The obtained OLHs can actively achieve full-spectrum light transport from 420
