Synthesis of fluorescent, responsive, conjugated polymers with emission color tunability |
| 초록 |
Water-soluble conjugated polymers have been attracted a great deal of attention because of their unique optoelectronic properties, which may serve as a basis for a new generation of optoelectronic devices and biochemical detection. Their peculiar properties stem from the combination of optoelectronic properties of conventional conjugated polymers and water solubility induced by ionic nature of polyelectrolytes. Their optoelectronic properties can be easily tuned through the structural alteration of the conjugated structure of the polymer backbones, and the ionic functionality endows them with exceptional features such as electrostatic interaction with oppositely charged species. We investigate aggregation-enhanced exciton migration in a anionic conjugated polymers containing green- and red-emitting exciton trap sites. We found that the polymer exhibited a visually noticeable blue-to-green and blue-to-red fluorescence color change upon aggregation with oppositely charged species. |
