Many organic and medicinal chemists are interested in the coumarin compounds due to their potential for use in pharmaceuticals and other industries. Coumarin compounds are a significant class of biologically active chemicals. Here, we outline the steps forproducing coumarin derivatives quickly and effectively from commercially accessible substrates via multicomponent condensation processes involving pyrone and benzene derivatives. These substances were examined for their potential anti-tumor effects, including their ability to block carbonic anhydrase, activate the cell apoptosis protein, and coumarin and its derivatives are the primary oral anticoagulants. Candida albicans, Aspergillus fumigatus, and Fusarium solani are three distinct fungus species that are resistant to the antifungal properties of synthetic coumarins. Long known are the coumarins' antibacterial due to its biological activities against some kinds of bacteria such as Zeitschrift für Naturforschung C, as well as their antifilarial, antiulcerogenic, anti-inflammatory, and antioxidant effects for its capacity to inhibit their growth activities. Coumarin has long been valued as a major raw element in the fragrance sector due to its distinct sweet aroma and stability. When mixed with organic essential oils like lavender, citrus, rosemary, and oak moss, it is used as an odour-enhancer to produce a long-lasting impact. It has been utilized as a bleaching or brightening agent in detergents when it revealed a remarkable brightening effect with excellent overall stability on fibers of synthetic origin. Materials such as liquid crystalline, organic/inorganic composites, as well as light harvesting, energy transferring compounds, and electro-optics materials are all employed as a dye in organic photo-redox catalysis and as potent photo-sensitizers reagent. These materials polymerize epoxy-silicones, under near-UV and visible light. Coumarin has also found useful as metal-free sensitizers for solar cells.

“…Due to the tunable fluorescence and absorbance properties [101] coumarin molecules are incorporated in numerous application fields such as OLEDs [31][32][33][34], optical data storages [35,36], or laser dyes [37,38]. Trenor et al and Wagner et al published detailed reviews of coumarin moieties and their photophysical properties some years ago [29,102].…”

“…The anchored coumarin showed similar luminescence compared to the molecular one despite the large spacer [106]. In another approach, Teixeira et al reported on the copolymerization of 3-vinylcoumarins and 7-hydroxy-3-vinylcoumarin with styrene and methyl acrylates and the resulting spectroscopic changes [34]. They discovered a bathochromic shift of the UV absorption maximum of 3-vinylcoumarin compared to 7-hydroxycoumarin due to the extension of the conjugated system.…”

Recent Advances in Functional Polymers Containing Coumarin Chromophores

et al. 2020

Natural and synthetic coumarin derivatives have gained increased attention in the design of functional polymers and polymer networks due to their unique optical, biological, and photochemical properties. This review provides a comprehensive overview over recent developments in macromolecular architecture and mainly covers examples from the literature published from 2004 to 2020. Along with a discussion on coumarin and its photochemical properties, we focus on polymers containing coumarin as a nonreactive moiety as well as polymer systems exploiting the dimerization and/or reversible nature of the [2πs + 2πs] cycloaddition reaction. Coumarin moieties undergo a reversible [2πs + 2πs] cycloaddition reaction upon irradiation with specific wavelengths in the UV region, which is applied to impart intrinsic healability, shape-memory, and reversible properties into polymers. In addition, coumarin chromophores are able to dimerize under the exposure to direct sunlight, which is a promising route for the synthesis and cross-linking of polymer systems under “green” and environment-friendly conditions. Along with the chemistry and design of coumarin functional polymers, we highlight various future application fields of coumarin containing polymers involving tissue engineering, drug delivery systems, soft robotics, or 4D printing applications.

“…Beyond 2004, many new developments in polymer technology, where coumarin plays a key role to achieve new functions and performance, have emerged. The photophysical properties of new coumarin-derived molecules continue to be used as active dyes in new polymer structures [74]. For example, some very recent reported scientific works deal with analysing the molecular level interaction of coumarin dopant as a foreign molecule at different concentrations within two different polymer matrices [poly(methyl methacrylate) and poly(vinyl alcohol)] [75].…”

Polyurethanes are of undoubted interest for the scientific community and the industry. Their outstanding versatility from tailor-made structures turns them into major polymers for use in a wide range of different applications. As with other polymers, new, emerging molecules and monomers with specific attributes can provide new functions and capabilities to polyurethanes. Natural and synthetic coumarin and its derivatives are characterised by interesting biological, photophysical and photochemical properties. Then, the polyurethanes can exploit those features of many coumarins which are present in their composition to achieve new functions and performances. This article reviews the developments in the proper use of the special properties of coumarins in polyurethanes to produce functional and smart materials that can be suitable for new specific applications.
