Abstrakt: 5 Conclusion PS samples with defined macroporous structure were prepared and they were used as sensing layer in PL chemical sensors' concentration dependence of pL quenching response of standard PS was measured ro,ío*orogical set of linear alcohols in gas and liquid phase. From oU*'""a *tl"l"tion' of quenching sensitivity with dielecnic constant and saturated vapour it""ut" in gas and liquid phases follolrs: r. :r _L^-a io .nnrrolled bv dielectric - PL quancbing response of PS in liquid phase is controlled by streng*r ofmlYta - PL quenching response of PS in gas phase is controlled more by equilibriumconcentrationofanalýeinsideporousmatrix.Dielectric strength of analýe is not so important. PSsurfaceswerefunctionalizedwithcobaltphthalocyanine, polypyrrole, permethyl-6r-heptenoylamino-6I-deoxy B-cyclodextrins' methyl-lO-undeceonate and by oxidation' (The work is focused on using the first three compounds') We performed a measurement of concentration dependence of PL sensor response functionalized PS samples for selected organic species in gas phase' We can conclude that the PL quenching.",pň," was modiťred by functionalization of PS with selected compounds, due to change of surface polarity and molecular recognition. The magnitude of sensor response modification is dependent on kind of anallte' Another...
