POLY 426 |
| Luminescent organoborane functionalized polystyrene has been prepared. The polymers are highly fluorescent in solution as well as in the solid state, and the emission color can be fine-tuned through modifications in the aryl substituents. Complexation studies of the polymers with different nucleophiles indicate that fluoride and cyanide bind strongly, as evident from the distinct changes in the absorption and emission spectra. More importantly the polymers show signal amplification, a property usually exhibited by conjugated polymeric sensors, indicating that polyolefins may be an interesting alternative to conjugated polymers for the sensing of nucleophiles. |
