GUMBOS (group of uniform materials based on organic salts) are a new class of solid organic ionic materials that shared similar properties as that of ionic liquids, but have a wider range of melting points from 25°C to 250°C. A large number of combinations have been made to design and synthesize multifunctional GUMBOS with tuned properties that are encouraged to explore these organic materials for various applications. Further, nanomaterials can be fabricated from GUMBOS through various reliable synthetic approaches. These nanomaterials have known as ‚nanoGUMBOS' that possessed advantageous properties at the nanoscale and can be used for target applications. Besides, the size, shape, and uniformity of nanomaterials can be tuned by varying different experimental parameters, and synthetic routes. This review is divided into two parts and presents all the published data regarding GUMBOS and nanoGUMBOS. The first part enclosed the synthesis of GUMBOS as well as their potential applications in the field of analytical, optoelectronics, biology, and sensor technology. In the second part, the synthesis of nanoGUMBOS using different methods and their applications in the field of cellular imaging, optoelectronics, catalysis, enantiorecognition, and sensor technology will be highlighted.
