was developed for the purpose of generating radicals via direct photoexcitation. These borates were prepared using 2,2′-(pyridine-2,6-diyl)diphenol as a tridentate ligand together with organoboronic acids or potassium trifluoroborates. The ready availability of organoboroncompounds is a significant advantage of this direct photoexcitation protocol. The excited states of these borates can also serve

An efficient photoredox-catalyzed three-component coupling reaction of aryl amine, glyoxalate and alkyltrifluoroborates has been reported. A variety of N-arylated aminoesters were constructed rapidly using an organic photocatalyst under mild conditions. Broad substrate scope and good functional group tolerance are the key features of this strategy.
hydrophobic moiety attached on a carboxylic or phosphoric acid terminal anchoring group, which chemisorbs on the semiconductor surface. In this work, the synthesis of a new family of 8-quinolinol derivatives bearing alkyl chains of variable length at the 5-position is described and their comparative efficiency as effective bidentate co-adsorbents in DSCs is evaluated. The key step towards their straightforward
