Recent Progress in Synthesis and Applications of Tunable Materials and Nanomaterials Based on Organic Salts

Abstract

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.

Improving the Antimycobacterial Drug Clofazimine through Formation of Organic Salts by Combination with Fluoroquinolones

“…Weaker Coulombic interactions and lower cohesive energies in the solid phase, due to a lack of ion symmetry and low charge density, confer to OSs unique properties, such as their much lower melting points compared to conventional salts and higher solubility compared to their parent organic building blocks [ 13 ]. A recent trend to classify this special group of OSs, irrespective of their melting points, is to gather them in the so-called Group of Uniform Materials Based on Organic Salts (GUMBOS) [ 16 , 17 , 18 ]. Regardless of which may be the most adequate terminology, pairing APIs with selected organic ions offers the possibility to fine-tune the biological and physicochemical properties of the resulting API-derived organic salts (API-OSs) [ 15 , 19 ].…”

A Review of GUMBOS: Tunable Ionic Materials

“…One of the primary driving forces for development and study of ionic materials is to investigate their use as environmentally friendly solvents with relatively low melting points and low volatility. Thus, use of these solvents reduces the level of volatile organic compounds in the atmosphere [1,2]. ILs are typically composed of an organic cation and an inorganic or organic anion with melting points at or below 100 °C [1,3].…”
