| Description
| - Zkoumány byly chemickocitlivé vlastnosti 4,4'-dimethoxy-2,2'-bipyrrolu a 4,4'-buthoxy-2,2'-bipyrrolu. Tyto nové vodivé polymery byly polymerizovány cyklickou voltametrií na platinových a zlatých prokládaných elektrodách navržených pro dvou a čtyřbodové měření laterální vodivosti. Takto získané polymery vykazovaly vysokou citlivost vůči HCl v řádu ppm. Byla analyzována kinetika vlivu plynného HCl na poměr vodivostí měřených dvou a čtyřbodovou technikou. Pozorována byla též odezva vůči NH3, NO a kyslíku, nicméně s mnohem nižší citlivostí než pro HCl. Ve vodném prostředí je vodivost filmů závislá na pH, přičemž vodivý rozsah je pro methoxy derivát posunut o dvě jednotky pH do kyselé oblasti. Demonstrována byla možnost použití filmů jako pH převodníku pro enzymový senzor. (cs)
- Chemosensitive properties of 4,4´-methoxy-2,2´-bipyrrole and 4,4´-buthoxy-2,2´-bipyrrole were investigated. These new conductive polymers were polymerized by cyclic voltammetry on the platinum and gold interdigitated electrodes designed for two and four point measurement of lateral conductivity. Thus obtained polymers demonstrated high sensitivity to HCl in the ppm concentration range. Kinetics of the gaseous HCl influence on the ratios of conductivities measured by 2- and 4-point techniques was analyzed. Some response of the polymers conductance toward NH3, NO and oxygen was also observed but with much lower sensitivity than towards HCl. In aqueous solutions the polymer conductivity was pH-dependent; in comparison with 4,4´-dibuthoxy-2,2´-bipyrrole, the conductivity range of the methoxy- derivative was shifted to acidic range for about two pH-units. A possibility to use of the pH-dependence for the development of enzymatic biosensors with pH-transducing was demonstrated.
