摘要：

Integrated microstructures composed of organic micro/nanocrystals have gained impressive interest recently as   probable candidate for constructing optoelectronic circuits. However, the fabrication of these designed composite structures remains a huge challenge. Herein, the sequentially self-assembled branched homostructures based on 1D single-crystalline organic microrods of 1,4-bis((E)-4-iodostyryl)-2,5-dimethoxybenzene through the facile solution-processing approach are demonstrated. The growth mechanism of these dendritic microcrystals with an angle of 75° between trunk and branch is attributed to the acet-selective growth principle between the (020) and (110) crystal planes, for which the interplanar spacing mismatch rate is as low as 6.1%. More significantly, this branched microstructure exhibits an asymmetric optical waveguide and can function as an optical logic gate with an ON/OFF ratio of 10.5. Therefore, the approach to build this organized multilevel structure could provide further applications as building blocks in integrated optoelectronic circuits.
