摘要

我们报告了亲水单元长度不同的 F-127 和 P-123 三嵌段共聚物胶束中的发光色素（LUM）的光物理。由于聚合物胶束的两亲性和亲水性电晕区，我们观察到了不同形式的 LUM。在 F-127 中，我们观察到 LUM 在 ∼ 430 nm 处有一个额外的发射峰，而 A10 阴离子形式的 LUM 的存在比例较低。通过时间分辨各向异性测量，我们发现 F-127 胶束中的 LUM 比 P-123 胶束中的 LUM 所面临的环境更受限制。

Photophysical properties of lumichrome in aqueous solution tri-block copolymers

We have reported the photophysics of lumichrome (LUM)) in tri-block copolymers micelles of F-127 and P-123, having differences in length of hydrophilic unit. Due to the amphiphilic nature of polymeric micelles, and hydrophilic corona region, we observed the existence of different forms of LUM. We observed an extra emission peak of LUM at ∼ 430 nm and less percentage of existence of the A10 anionic form of LUM in case F-127. From time resolved anisotropy measurement, we have found that the LUM in F-127 micelle faced a more restricted environment than P-123 micelle.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
