Abstract
The invention belongs to the technical field of fluorescent probes for H2S detection, and provides a triphenylamine derivative, a preparation method thereof, and application of the triphenylamine derivative in double-channel fluorescence detection of hydrogen sulfide. According to the triphenylamine derivative, a piperazine ring is adopted to connect triphenylamine and an NBD group, the molecularformula of the triphenylamine derivative is C29H24N6O4, and the structural formula of the triphenylamine derivative is shown in the specification. The compound has two excitation wavelengths, namely,325 nm and 485 nm; and when excited with the two different excitation wavelengths, the fluorescence spectrum of the compound is highly selectively responsive to H2S. The triphenylamine derivative prepared by the invention is simple to synthesize, high in sensitivity to H2S dual-channel fluorescence detection, quick in response and wide in linear range. The color of the compound is obviously changed before and after reacting with H2S, and can visually detect H2S.
