“…Due to their significant properties and fine tunablity, GUMBOS have become potential candidates in versatile fields like extraction, separation, sensors, biocatalysis, and electrochemistry, fabrication of active pharmaceutical ingredient loaded drug carriers, microemulsion, and energy conversion field in the last decades. [27,[36][37][38][39][40][41][42][43][44][45][46] Since the acid-base equilibrium process occurs in aqueous solutions and non-polar to polar organic solvents, several traditional organic dyes having capability as a chromogenic indicator in aqueous solutions have been modified so far within the building blocks of ILs for the visualization of acid-base equilibrium process in non-aqueous solvents. [45][46][47] Potentially, these IL-integrated acid-base sensors may have versatile applications that avoid using volatile solvents and allow strong interactions with analytes because of their high concentrations, thus increasing practical applications.…”

Visualizing acid-base equilibria and determining acid-base equilibrium constants (pK a ) in aqueous to the non-aqueous medium is essential for understanding the various chemical and biochemical processes. This mini review highlights the possibility of fine-tuning the traditional acid-base indicator dye's physicochemical properties into ionic liquids (ILs)-integrated ones to enhance their solubility and practical applications in a wide range of solvents. These include the high sensitivity towards acid and bases by virtue of its colour and spectral properties changes. ILs-based indicators could be used to determine the pK a values in aqueous to the non-aqueous medium from polar to non-polar ones by overlapping indicator method. This review provides an essential idea of the emerging challenges and openings that may motivate the scientific communities to move towards IL-integrated acid-base indicators and find their dissociation constants (pK Ind ) in any solvents depending on their solubility. The calculated pK Ind values could be used to determine the pK a values of different acids and bases in any solvents. It would also be beneficial to find a general trend of acidity and basicity from solvents to solvents using such types of indicators without alternating the main moiety. It will benefit the scientific communities to understand the pK a scales in different solvents.

“…Over a decade ago, the research group of Warner at Louisiana State University introduced some solid organic ionic salts, called 'GUMBOS' (group of uniform materials based on organic salts) that shared almost similar properties as that of ILs but possessed a wide range of melting point (25À 250°C), exploring them in various biomedical and material applications. [54][55] Thus, a new term ‚GUMBOS' was introduced by this research group to differentiate the chemistry of RTILs from solid ILs and other relative solid organic ionic salts. [46] [55] Thus, several GUMBOS with a melting point below 100°C can also be classified as FILs (Figure 1).…”

“…[46] [56] Using different ionic pairs, several GUMBOS have been designed for a target applica-tion. [55] [57] Although, GUMBOS shares similar properties as that of ILs, these materials are more amenable to biomedical, material, and analytical applications. In addition to this, various reports introduced controlled fabrication of nanomaterials from the synthesized GUMBOS using reliable strategies, their characterization, and applications in several fields.…”

“…These nanomaterials have known as "NanoGUMBOS" which combined the adaptability of GUMBOS and associated with fascinating properties at the nanoscale. [55] Hence, the fabricated nanomaterials exhibited awesome properties including luminescent character, magnetism, fluorescent behavior, chirality, and conductivity. [54,101,112,128] These properties are encouraged to utilize these nanomaterials for target purposes.…”

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.
