摘　　要：Tunable light-matter interactions are exhibited by organic low-dimensional crystals,making these crystals a promising platform for organic photonics.However,the precise synthesis of organic low-dimensional crystals remains challenging due to the stochastic nature of molecular nucleation processes.Herein,the directed nucleation process is driven by the introduction of metastable seed-crystals as the trunk,which ultimately leads to branched-array organic heterostructures.The successful formation of organic heterostructures with high-density branched arrays is attributed to the highest attachment energy(E_(att)(023)=-104.25 kcal mol^(-1))of the exposed(023)crystal plane during the seed-crystal growth route.Significantly,these as-prepared heterostructures inherently have an ultralow lattice mismatch ratioηof 0.7%between trunk and branch,which contributes to the multi-channel photon transportation.Therefore,this work provides valuable insights into a versatile synthetic strategy for accessing low-dimensional heterostructures for integrated optoelectronics.
