Tuning the optoelectronic properties of cyanine and ketocyanine dyes by incorporation of 9,9-di-n-propylfluorenylindolenine

The synthesis and properties of novel cyanine and ketocyanine dyes incorporating 9,9-di-n-propylfluorenyl units is reported. While bathochromic shifts of order 100 nm are observed in cyanines for addition of each vinylene unit (lengthening the methine cha

N-alkylated linear heptamethine polyenes as potent non-azole leads against Candida albicans fungal infections

In this study, eighteen heptamethine dyes were synthesised and their antifungal activities were evaluated against three clinically relevant yeast species. The eighteen dyes were placed within classes based on their core subunit i.e. 2,3,3-trimethylindolenine (5a-f), 1,1,2-trimethyl-1H-benzo[e]indole (6a-f), or 2-methylbenzothiazole (7a-f). The results presented herein imply that the three families of cyanine dyes, in particular compounds 5a-f, show high potential as selective scaffolds to treat C. albicans infections. This opens up the opportunity for further optimisation and investigation of this class compounds for potential antifungal treatment.

Spectroscopic characterization of heptamethine cyanine dyes for the interaction with the CN- and F-

The selectivity and sensitivity of a benzoindolium heptamethine cyanine dyes toward CN- and F- in DMSO are described. These anions interact with Dye-1 and Dye-2 forming anion-Dye adducts, the formation of which was supported by the Pariser-Parr-Pople molecular orbital (PPP MO) calculation. The different optical responses in Dye-1 stimulated by addition of CN- (blue to pale yellow) and F' (blue to pink) allow simultaneous estimation of CN- and F-. Copyright Taylor and Francis Group, LLC.
