Abstract
In recent years, there has been a lot of focus on aggregation-induced emission materials, and most of the research has focused on the unidirectional conversion from ACQ (aggregation-causing quenching) to AIE (aggregation-induced emission), which inevitably requires complex chemical synthesis and cumbersome processes, and molecules with reversible ACQ and AIE conversion characteristics are rarely reported. In order to achieve a reversible conversion based on a single material between ACQ and AIE properties, we have developed a new functional material, DBPZ-2 (1,4-bis((4-(benzo[c] (Li et al., 2020; Hu et al., 2014; Song et al., 2024) [1,2,5]thiadiazol-4-yl)piperazin-1-yl)methyl)benzene). This compound exhibits AIE properties under neutral conditions, and interestingly, it exhibits significant ACQ properties when protonated, and then restores AIE properties after simple deprotonation. Furthermore, the sensitive response of DBPZ-2 to pH can be used as a fluorescent probe to monitor the changes in the pH value of cellular lysosomes, which brings hopes for future research on lysosomal biology and related diseases.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
