Solid-state electrochromic devices using pTMC/PEO blends as polymer electrolytes
Barbosa, P. C.; Rodrigues, L. C.; Silva, Maria Manuela; Smith, Michael John; Parola, A. J.; Pina, F.; Pinheiro, CarlosFlexible, transparent and self-supporting electrolyte films based on poly(trimethylene carbonate)/poly(ethylene oxide) ((p(TMC)/PEO) interpenetrating networks doped with LiClO4 were prepared by the solvent casting technique. These novel solid polymer electrolyte (SPE) systems were characterized by measurements of conductivity, cyclic voltammetry, differential scanning calorimetry and thermogravimetry. The incor...
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...

Melo, J. Seixas de; Pina, J.; Pina, F.; Lodeiro, C.; Parola, A. J.; Lima, J. C.; Teresa Albelda, M.; Paz Clares, M.; Garcia-España, EnriqueTwo new fluorescent macrocyclic structures bearing two naphthalene (Np) units at both ends of a cyclic polyaminic chain were investigated with potentiometric, fluorescence (steady-state and time-resolved) and laser flash photolysis techniques. The fluorescence emission studies show the presence of an excimer species whose formation depends on the protonation state of the polyamine chains implying the existence ...
