Squaraine dyes derived from indolenine and benzo[e]indole as potential fluoresc...
Gomes, Vanessa Sofia Dias; Ferreira, João C. C.; Boto, Renato E. F.; Almeida, Paulo; Fernandes, Jose R.; Sousa, Maria João; Gonçalves, M. Sameiro T.Four squaraine dyes derived from 2,3,3-trimethylindolenine and 1,1,2-trimethyl-1H-benzo[e]indole with different combinations of barbituric groups attach to the central ring, having ester groups and alkyl chains in the nitrogen atoms of heterocyclic rings were synthesized. These dyes were fully characterized and their photophysical behavior was studied in ethanol and phosphate-buffered saline solution. Absorptio...
Squaraine dyes as serum albumins probes: synthesis, photophysical experiments a...
Gomes, Vanessa Sofia Dias; Boto, Renato E. F.; Almeida, Paulo; Coutinho, Paulo J. G.; Pereira, Mário R.; Gonçalves, M. Sameiro T.; Reis, Lucinda V.Three barbiturate squaraine dyes derived from indolenine or benzothiazole, with different barbituric acid derivatives were prepared, characterized and photophysically evaluated by standard spectroscopic methods. As expectable for squaraines, these dyes showed narrow and intense absorption and emission bands in the Vis/NIR region. The interaction of synthesized dyes with bovine and human serum albumins (BSA and ...
