Asuman AŞIKOĞLU BOZKURT [1]


This study deals with comparing interaction mechanisms of 2(3), 9(10), 16(17), 23(24)-Tetra-((5-bromo-2-methoxyphenyl)diazenyl) phthalocyaninatozinc(II) (zinc phthalocyanine) thin film with versatile chemical vapours: stable and electron donating aromatic vapours namely; benzene, toluene and xylene. The variation in electrical conductivity of zinc phthalocyanine is used as an indicator of the BTX- zinc phthalocyanine interactions. It was found that, unexpectedly, the exposure of the sensor surface to BTX vapors cause an increase in sensor current. It was observed for low concentrations of BTX vapours that, zinc phthalocyanine based sensor exhibits maximum and minimum sensitivities towards toluene and xylene vapors, respectively. However, the maximum and minimum sensitivities of the sensor gradually changes from xylene to benzene for high concentrations of BTX vapors. These findings was concluded in the framework of reaction activation energy and the presence of some water dissociated species, such as H+ or OH.

Bu çalışmada; benzen, toluen ve ksilen gibi elektron veren stabil aromatik buharların 2(3), 9(10), 16(17), 23(24)-Tetra-((5-bromo-2-methoxyphenyl)diazenyl) phthalocyaninatozinc(II) (Çinko ftalosiyanine) ince film mekanizması ile etkileşimi karşılaştırılmıştır. Çinko ftalosiyanine’in elektriksel iletkenlikteki değişimi, BTX- çinko ftalosiyanine etkileşiminin bir göstergesi olarak kullanılır. Sensör yüzeyinin BTX buharlarına maruz kalması, sensör akımında beklenmedik bir artışa neden olmaktadır. Düşük BTX buhar konsantrasyonlarında, çinko ftalosiyanine sensörü toluen buharlarına maksimum, ksilen buharına minimum hassasiyet göstermektedir. Ancak, yüksek BTX buhar konsantrsanyonlarında ksilen için maksimum, benzene için minimum duyarlılık görülmüştür. Bu bulgular, H+ ve OH gibi bazı ayrışmış su moleküllerinin varlığı ve reaksiyon aktivasyon enerjisinin sonucudur.
