“…The nearly ubiquitous presence of UV–vis use in the chemistry curriculum has been documented extensively in this Journal , as well as others. UV–vis spectrometers are a natural component of the analytical chemistry laboratory, − and are also commonly found in upper level undergraduate chemistry courses such as inorganic − and physical chemistry. − In organic chemistry, UV–vis instruments are occasionally used to study highly colored products, , polymers, and have found some applications in green chemistry synthesis . Biochemistry relies on several techniques that are based on UV–vis absorbance measurements, including the classic Bradford and Lowry protein assays and nucleic acid extraction purity determinations .…”

Exploring Divergent Green Reaction Media for the Copolymerization of Biobased Monomers in the Teaching Laboratory

et al. 2020

Polymerization reaction media can have a profound effect on the physical properties of the resultant polymer. This phenomenon is showcased in a new experiment for the organic chemistry and polymer science teaching laboratories wherein the radical copolymerization of biobased β-myrcene and dibutyl itaconate is performed using a nonhazardous aqueous emulsion solvent and compared to a bulk reaction. Both procedures demonstrate multiple green chemistry principles and application to sustainable polymer synthesis. The emulsion copolymerization produces a tacky, elastomeric cross-linked material, capable of swelling to many times its original volume in organic solvents, setting the stage for the exploration of the relationship between solvent polarity and swelling capacity. Conversely, the polymerization of β-myrcene and dibutyl itaconate in the bulk yields a viscous non-cross-linked polymer whose 1H NMR spectrum is suitable for student analysis and estimation of polymer number-average molar mass (M n), monomer conversion, and copolymer composition. This inexpensive experiment models the use of renewable feedstocks, the effect of reaction medium on polymer architecture, the unique properties of cross-linked organogels, and the quantitative analysis of polymer structure using 1H NMR spectroscopy.

Sunscreens are used to prevent skin damage due to sunlight ultraviolet radiation (UVR). These compounds can be obtained from natural solar filters, from nanocompounds and, mainly, from synthetic organic compounds. The production of ideal organic sunscreens is related to a better understanding of safety and efficacy of these compounds. The ideal organic sunscreens must protect the skin against UVB-rays (290-320 nm) and UVA-rays (320-400 nm), also presenting a safe sun protection factor (SPF), have good photostability and do not present phototoxicity. This review reports the main general aspects, synthesis and scientific studies of organic and commercial sunscreens.
