AI Article Synopsis
- Researchers synthesized a fluorescent compound called (pyren-1-yloxy)-acetic acid (Py) from 1-hydroxypyrene, which formed a responsive gel in dimethylformamide and water.
- Using this gel, they built a layered artificial light-harvesting system by adding fluorescent dyes like perylene 3, 9-dicarboxylic acid and rhodamine 6g.
- This setup allowed for a gradual color change in fluorescence from blue-purple to green and red, ultimately achieving white light emission by tweaking the proportions of the different dyes.
Article Abstract
The molecular (pyren-1-yloxy)-acetic acid (Py) with excellent fluorescence properties was synthesized from 1-hydroxypyrene (Hp) and formed a supramolecular gel with an acid-base stimulus response in dimethylformamide and water. On the basis of gel, the fluorescent dye perylene 3, 9-dicarbxylic acid, and rhodamine 6g were added successively to construct a step-by-step artificial light-harvesting system, so that the fluorescence color changed from blue-purple to green to red, and white light emission was realized by adjusting the ratio of donors and acceptors.
