Volpi, G.; Garino, C.; Fresta, E.; Casamassa, E.; Giordano, M.; Barolo, C.; Viscardi, G. published an article in 2021. The article was titled 《Strategies to increase the quantum yield: Luminescent methoxylated imidazo[1,5-a]pyridines》, and you may find the article in Dyes and Pigments.SDS of cas: 135-02-4 The information in the text is summarized as follows:
A series of methoxylated imidazo[1,5-a]pyridines is presented and their optical and electrochem. properties investigated and interpreted on the basis of d. functional theory calculations The photophys. properties are discussed in relation to the chem. structure. The key role of the 1,3 substitutions on the imidazo[1,5-a]pyridine nucleus on rotational barriers and on frontier MOs is discussed in relation to the exptl. hyperchromic effect, photoemission quantum yield and electrochem. properties. Depending on the position of the introduced methoxy substituents on the imidazo[1,5-a]pyridine nucleus, we are able to tune the Stokes shift and to increase the emission quantum yield from 22% to 50%. The results came from multiple reactions, including the reaction of 2-Methoxybenzaldehyde(cas: 135-02-4SDS of cas: 135-02-4)
2-Methoxybenzaldehyde(cas: 135-02-4) is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. It also has been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.SDS of cas: 135-02-4
