“…10g 1D branched heterostructures and homostructures at micro/nanoscale can be prepared by various methods, including solvent slow evaporation method [48,105,106], twostep solution and vapor deposition process [30] and one-pot solution method [47]. 1D branched micro/nanostructure with fine photonic properties can be used in optical routers [30,47,107,108], asymmetric optical waveguide [48,106] and multichannel signal converter [109,110]. Dendritic organic heterojunctions with aluminum tris (8hydroxyquinoline) (Alq 3 ) microwire trunks and 1,5-diaminoanthraquinone (DAAQ) nanowire branches (Fig.…”

Optical waveguide of organic micro/nanocrystals is one of crucial elements in miniaturized integrated photonics. One-dimensional (1D) organic crystals with various optical features have attracted increasing interests towards promising photonic devices, such as multichannel signal converter, organic field-effect optical waveguide, sensitive detector, and optical logic gate. Therefore, a summary about the 1D organic micro/nanocrystals based optical waveguide is important for the rational design and fabrication of novel optical devices towards optoelectronics applications. Herein, recent advances of optical waveguide based on 1D organic micro/nanocrystals with solid, flexible, hollow, uniformly doped, core-shell, multiblock and branched structures are summarized from the aspects of the waveguide properties and applications in photonic devices. Furthermore, we presented our personal view about the expectation of future development in 1D organic optical waveguide for the photonic applications. Graphical abstract

“…Precise control of the morphology with a defined shape and dimension for organic micro/nanostructures is of critical importance due to their potential application in miniature photonic devices such as photonic detectors [73,74], optical waveguides [75] as well as optical sensors [76]. The popular strategy is designing a molecular architecture that includes functional groups, so their anisotropic interactions can generate the desired microphase separation and local packing [77][78][79].…”

Organic micro/nanocrystals based on small organic molecules have drawn extensive attention due to their potential application in organic field-effect transistors, electrochemical sensors, solar cells, etc. Herein, the recent advances for organic micro/nanocrystals from the perspective of molecule aggregation mode, morphology modulation, and optical property modulation are reviewed. The stacking mode and the intermolecular interaction depend on the molecular structure, which eventually determines the morphology of organic micro/nanocrystals. The morphologies of the organic micro/nanocrystals make the aggregates exhibit photon confinement or light-guiding properties as organic miniaturized optoelectronic devices. In this review, we conclude with a summary and put forward our perspective on the current challenges and the future development of morphology and optical tunable direction for the organic micro/nanocrystals.

“…4,5 Utilizing polarization-sensitive materials that can directly generate polarized light is a promising route to manipulate photons at the micro/nanoscale. [6][7][8][9][10][11][12] Benefiting from tailorable excited-state processes, abundant intermolecular interactions and high optical orientation, [13][14][15] organic microcrystals provide an ideal platform to precisely control the polarization of photoluminescence (PL). [16][17][18][19] Nevertheless, the emitted light from these materials generally suffers from a limited degree of polarization (DOP) owing to the relatively small projection of the transition dipole moment (m) at the optical excitation plane, which impedes their practical applications in modern optoelectronics.…”
