Abstract Two low band-gap polymers (gap energy ∼1 eV) based on carbon-bridged dithienyl monomers have been investigated by density functional theory (B3LYP/6-31G) and semiempirical/CI methods. Theoretical absorption spectra from monomers to pentamers were obtained and showed good agreement with the experimental spectra of the polymers. Comparison with data for oligomers of CDM and BDT (dithiophene derivatives indicated that the new polymers have a small band gap and could fulfill the conditions for ...

... Pernambuco and one region of the State of Amazonas. Pathogenicity tests were carried out using onion leaves and bulbs. All strains were capable of causing disease in leaves, causing a variable degree of lesions on the leaves; four strains caused the most severe damage. In the onion bulb tests, only three of the above strains caused lesions. Seven primers of arbitrary sequences were used in the RAPD analysis, generating polymorphic bands that allowed the separation of the strains into three distinct groups. The amplification products generated with the primers ITS1 and ITS4 also showed polymorphism when digested with three restriction enzymes, DraI, HaeIII and MspI. Only the latter two demonstrated genetic variations among the strains. These two types of molecular markers were able to differentiate the strain from the State of Amazonas from those of the State of Pernambuco. However, ...
