Abstract

AbstractIntegrated hierarchical microstructures composed of organic micro/nanocrystals with defined morphology have received great interest as candidates for advanced photonic circuits. Herein, the synthesis of highly ordered multilevel homogenous hyperbranched networks (HHNs) made of the individual organic compound 2, 3‐dicyanine naphthalene via a facile solution self‐assembly route is reported. The selective growth of branches on the sidewall of the backbone driven by the lattice match mechanism leads to the formation of higher‐level snowflake‐like configuration of the HHNs. These well‐organized HHNs perform excellent abilities of directional asymmetry photon transport and hierarchical polarization filtering. Combined with the doping strategy, the broad emission range of hyperbranched network heterostructures is expanded, and even the white light emission with Commission Internationale de L'Eclairage coordinates at (0.30, 0.33) is realized. This work provides deep insight into the rational creation of complex organic heterostructures for novel photoelectric devices with desired performances.
