Title (EN) THIOPHENE BASED OLIGOMERS AS LIGHT ACTIVATED BIOCIDES
(FR) OLIGOMÈRES À BASE DE THIOPHÈNE EN TANT QUE BIOCIDES PHOTOACTIVÉS
Abstract: front page image
(EN)Thiophene containing water-soluble oligomers were synthesized and characterized. The photophysical properties of these compounds were studied; transient absorption spectroscopy was used to probe the triplet excited state and their ability to sensitize singlet oxygen was spectroscopically monitored in deuterated methanol. The above compounds were tested for their light activated biocidal properties against S. aureus both under UV and visible radiation. Among the oligomers studied, the terthiophene derivative was found to kill the bacteria efficiently.
(FR)L'invention concerne des oligomères hydrosolubles contenant du thiophène qui ont été synthétisés et caractérisés. Les propriétés photophysiques de ces composés ont été étudiées ; une spectrométrie d'absorption transitoire a été utilisée pour sonder l'état excité de triplets et leur capacité à sensibiliser l'oxygène singulet a été analysée par spectromicroscopie. Ces composés mentionnés ci-dessus ont été étudiés pour leurs propriétés biocides photoactivées contre S. aureus à la fois sous rayonnement UV et sous rayonnement dans le domaine visible. Parmi les oligomères étudiés, l'action biocide du dérivé de terthiophène sur ladite bactérie s'est avérée efficace.
