Abstract The utilization of organic cocrystal‐based superlattice materials (OCSMs) in the field optoelectronics is experiencing significant advancements attributable to their accurate stoichiometric coefficient and distinctive supramolecular self‐assembly structures. Herein, an exhaustive review on development OCSMs reported over past few years presented, with a primary focus following major aspects. First, emerging nanostructures primarily consist hydrogen‐bonded frameworks (HOFs) halogen‐bonded (XOFs), innovative cocrystal heterostructures (OHSs), nanomeshes (OMSs). Further, comprehensive summary provided investigation crystals film preparation techniques for OCSMs, which encompasses liquid‐phase growth, physical‐vapor‐transfer methods, solid‐phase processes. characteristics tunable fluorescence emission rapid stimulus response exhibited by these as well applications memristors, photothermal conversion imaging, sensors, FETs, spin devices, are also elucidated. mechanisms underlying charge transfer effects, π–π interactions, hydrogen bonds, halogen bonds finally analyzed provide valuable insights into material design promising applications.
