1. Structural and thermal properties of carboxylic acid functionalized polythiophenes
Polythiophenes functionalized with polar groups at the end of side-chain have emerged as an alternative method to obtain good compatibility between this class of conjugated polymers and electron acceptor compounds. The aim is to prevent phase segregation and to improve the efficiency of the polythiophene technological devices. However, homopolymers synthesiz

4. Síntese e caracterização de derivados do politiofeno para utilização em sensores / Synthesis and characterization of polythiophene derivatives and their use in VOCs sensor applications
The conjugated polymers, especially polythiophenes, have emerged as alternative materials to obtain chemically selective layers in gas sensors. The main advantages of these materials are the possibility of obtaining sensing devices that operate at room temperature and the diversity of materials. For example, a simple modification of the side chain of polythi

5. Estrutura eletronica de polimeros conjugados : a influencia da desordem
The present work is dedicated to the theoretical study of effects observed in organic conjugated polymers in which disorder plays an important role. The following problems have been chosen for study: (1) Chemical reaction of polyanilines in acidic solutions. It is well known that protonation doping leads to insulator-to-metal transition in some forms of poly
