Abstract
In this contribution, the 1,6,7,12-tetrachloroperylene diimide derivative (TClPDIs) with first reduction potential of − 0.0117 V was chosen for detection of hydrazine based on colorimetric probe, fluorescence quenching and chemical sensor. Interaction of TClPDIs with hydrazine in N,N-dimethylformamide lead to a red shift in the maximum absorption and fluorescence quenching as a result of reduction. Consequently, the yellow TClPDIs solution transform to green, the linear range of the determination of hydrazine was 0.317–2.895 nmol (R2 = 0.989) for colorimetric detection. Furthermore, the linear range of determination for hydrazine based on fluorescent quenching of TClPDIs was 0.645–3.57 nmol with a correlation coefficient R2 = 0.986. Thin film devices of TClPDIs with different thickness (20, 40 and 60 nm) deposited on interdigital electrodes were chosen to study the sensitive detection and quantification of organic amine vapors by monitoring the changes of its current intensity under ambient conditions. This chemical sensor showed different sensitivity towards different organic bases. These results indicated that the TClPDIs is a favorable candidate for the detection of hydrazine using reduction mechanism.
