Abstract

The invention relates to the technical field of fluorescence probes, in particular to an acid pH probe compound and a production method thereof. Triphenylamine compounds can be used as induced luminescence materials due to good fluorescence performance, and a schiff base structure has good coordination capability and protonation capability so that triphenylamine schiff base fluorescence compoundscan be used as pH sensing materials excellent in performance. However, the stability, especially in an acid water environment, of the schiff base structure under an acid condition is not ideal, and hydrolysis is prone to happen so that most of the schiff base structure pH probe compounds can hardly adapt to detection under strong acid water body conditions. The invention provides the acid pH fluorescence probe compound novel in structure; and the acid pH probe compound novel in structure has a good response effect in a pH range of 2-7, can adapt to strong acid water body environments, and hasimportant significance when applied for water body detection.

Description

technical field

[0001] The disclosure relates to the technical field of fluorescent probes, in particular to a pH probe compound suitable for strong acidic environments and a preparation method thereof. Background technique

[0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art.

[0003] Triphenylamine and its derivatives have relatively high hole mobility and good fluorescence properties, and are widely used in the construction of branched groups in multi-dendritic optoelectronic materials and the formation of rotation units in aggregation-induced luminescent materials. On the other hand, due to the lone pair of C=N electrons, Schiff base compounds have good coordination ability and protonation ability, a...
