1. Nonlinear optical properties of aniline oligomers / Propriedades ópticas não-lineares de oligômeros de anilina
We report on the study of electronic optical non linearities in two aniline oligomers: dimer and the tetramer. Four tetramer concentrations were measured, pure and also 33 and 100% doped; one of dimer non doped another 100% doped. The solutions were prepared using dimethyl sulfoxide (DMSO) as solvent and the doping was performed with hydrochloric acid. The s

2. Hiperpolarizabilidades Semi-EmpÃricas de Sistemas OrgÃnicos Doador-Receptor
The research on new nonlinear materials finds in Quantum Chemistry the possibility of designing organic molecules with optimized performance. It is performed by matching adequate components of structure, that is, a bridge (B) and an efficient donor(D)/acceptor(A) pair. Hence, some classes of D/A organic molecules were designed and theoretically observed to h

3. Transformation of Halogen-, Alkyl-, and Alkoxy-Substituted Anilines by a Laccase of Trametes versicolor†
The laccase of the fungus Trametes versicolor was able to polymerize various halogen-, alkyl-, and alkoxy-substituted anilines, showing substrate specificity similar to that of horseradish peroxidase, whereas the laccase of Rhizoctonia praticola was active only with p-methoxyaniline. The substrate specificities of the enzymes were determined by using gas chr
