Organic heterostructures (OHSs) consist of organic micro/nanocrystals are of essential importance for the construction of integrated optoelectronics in the future. However, the scarcity of materials and the problem of phase separation still hinder the fine synthesis of OHSs. Herein, based on the α phase one-dimensional (1D) microrods and the β phase 2D microplates of one organic compound 3,3′-((1E,1′E)-anthracene-9,10-diylbis(ethane-2,1-diyl))dibenzonitril (m-B2BCB), we facilely synthesized the OHSs composed of these two polymorph phases, whose growth mechanism is attributed to the low lattice mismatch rate of 5.8% between (001) plane of α phase (trunk) and (010) crystal plane of β phase (branch). Significantly, the multiport in/output channels can be achieved in the OHSs, which demonstrates the structure-dependent optical signals with the different output channels in the OHSs. Therefore, our experiment exhibits the great prospect of polymorphism in OHSs, which could provide further applications on multifunctional organic integrated photonics circuits. fine synthesis, polymorph, heterostructure, integrated optoelectronics, lattice mismatch Citation:

1 Introduction Up to now, with the increasing demand for high-performance optoelectronic devices like field-effect transistors (FETs) [1– 5], optical waveguides [6–8], and light-emitting diodes [9– 11], organic heterostructures (OHSs) are emerging as a promising approach to integrate multi-component materials [12,13], such as core/shell [14,15], branched [16,17], and triblock [18,19] structures have been fabricated and realized in optoelectronic devices. Moreover, heterostructures can integrate multiple components into one structure to overcome the challenge of single output channel and provide feasibility for realizing more transmission modes [20,21]. Recently, the researchers successfully have demonstrated the *Corresponding author (email: [email protected])
