Structurally Simple Dipolar Organic Dyes Featuring 1,3-Cyclohexadiene Conjugated Unit for Dye-Sensitized Solar Cells
摘要:
A series of structurally simple dipolar light-harvesting organic dyes featuring 1,3-cyclohexadiene in the aromatic pi framework for dye-sensitized solar cells has been synthesized and characterized. The highest conversion efficiency of the DSSCs based on these dyes can reach up to 4.4%.
Synthesis of Triphenylamine-Modified Arylates and Ketones via Suzuki Coupling Reactions
摘要:
[image omitted] A series of triphenylamine-mdified arylates and ketones were synthesized via Pd-catalyzed Suzuki coupling reaction of triphenylamine boronic acid with aryl bromide. The triphenylamine boronic acid was synthesized by iodization of 4-bromoaniline, Ullmann reaction of 1-bromo-4-iodobenzene with diphenylamine, and boronic acidification of 4-bromotriphenylamine.
