The effect of gamma-cyclodextrin addition in the self-assembly behavior of pyre...
Costa, Telma; Melo, J. S. Seixas deThe interaction between poly(acrylic acid) polymers (PAA) of low- (2000 g/mol) and high- (450,000 g/mol) molecular weight (Mw) hydrophobically modified with pyrene (PAAMePy) and beta- and gamma-cyclodextrins (beta-CD, gamma-CD) was investigated with fluorescent techniques. The interaction with beta-CD promotes little variation in the spectral and photophysical behavior of the polymer, whereas significant change...
Intramolecular excimer formation and sensing behavior of new fluorimetric probe...
Lodeiro, C.; Lima, J. C.; Parola, A. J.; Melo, J. S. Seixas de; Capelo, J. L.; Covelo, B.; Tamayo, A.; Pedras, B.A new family of compounds able to promote host-guest interactions with specific molecules (e.g., cyanuric and parabanic acids) and to coordinate metal ions, namely Zn(II) and Cu(II), has been synthesized and fully characterized. The new probes derive from the attachment of two methylaminopyrene units to the carbonyl precursor 2,6-bis(2-formylphenoxymethyl)pyridine. ; http://www.sciencedirect.com/science/arti...
