Electron transfer between adjacent layers in self-assembled films
(Elsevier B.V., 2000-01-21)
A simple model of electron transfer is adapted to explain fluorescence quenching in self-assembled films of poly( p-phenylene vinylene) (PPV) alternating with poly(thiophene acetic acid) (PTAA). Quenching is caused by a ...
Electrosynthesis and Characterisation of Polymer Nanowires from,Thiophene and its Oligomers.
Validating methodology formerly reported, polythiophene electrosynthesised as nanowires from the monomer and some of its oligomers is now described. The work is conducted on a platinum electrode previously modified with a ...

Cálculos de estrutura eletrônica aplicados ao estudo de sensores químicos baseados em polímeros: derivados de politiofeno
(Universidade Estadual Paulista (Unesp), 2018-11-28)
Polymeric materials are promising candidates for the manufacture of chemical sensors mainly due to their high versatility of synthesis and low relative cost. In this context, polythiophene derivatives have been considered ...
Optical VOCs detection using poly(3-alkylthiophenes) with different side-chain lengths
(ELSEVIER SCIENCE SA, 2009)
The use of conjugated polymers in the gas and volatile organic compounds (VOCs) detections represents an advance in the development of the electronic noses. Polythiophenes show good thermal and environmental stability, are ...
Electrochemical behaviour of Vanadium(V) on electrochemically synthesized magnetite film electrodes
(Elsevier Science Sa, 2018-06)
In this work, the electrochemical response of Vanadium(V) species on magnetite film electrodes is investigated. Magnetite is deposited electrochemically on glassy carbon electrodes, with an intermediate layer of poly(thiophene) ...
