Abstract

The invention relates to an amphiphilic Tb (III) complex, a preparation method thereof and a preparation method and application of fluorescent nano-fibers. By virtue of characteristics of a rigid framework, biocompatibility and self-assembling of cholesterol molecules, the amphiphilic Tb (III) complex containing a cholesterol structural unit and bi-picolinic acid is designed and prepared, the supermolecule fluorescent nano-fibers based on the amphiphilic Tb (III) complex are assembled, and action mechanisms of the fluorescent nano-fibers and aurintricarboxylic acid are researched; by virtue of synergetic complexing between aurintricarboxylic acid and ions of Tb (III) and an energy transfer process, aurintricarboxylic acid is efficiently sensed. Related reaction conditions are mild and easy to achieve, the preparation method of the fluorescent nano-fibers is simple, convenient and easy to operate, the prepared fluorescent nano-fibers are uniform in size, the sensitivity for detecting aurintricarboxylic acid is high, the selectivity is good, and the fluorescent nano-fibers are hopeful for being used for researching the pharmaceutical process of aurintricarboxylic acid.

Description

technical field

[0001] The invention belongs to the technical field of supramolecular sensing materials, and specifically relates to an amphiphilic Tb(III) complex, a preparation method thereof, and a preparation method and application of fluorescent nanofibers. Background technique

[0002] Aurintricarboxylic acid (Aurintricarboxylic acid, ATA) is an aromatic acid derivative, which can inhibit the interaction between protein and nucleic acid in cells, thereby inhibiting cell growth and division. For example: it was found to inhibit the replication of influenza A virus, and it has also been shown to block the invasion of the gp120 molecule on the surface of HIV to the CD4 receptor of T cells. Therefore, ATA is expected to be used in the control and treatment of certain diseases, and monitoring the performance of ATA in living organisms is crucial to the study of the pharmacological process of ATA, so the development of ATA sensors with excellent performance will greatly prom...
