An alternative reaction mechanism of the polymerization of diphenylacetylelnes using a catalytic system composed of tungsten(VI) chloride and tetraphenyltin has been proposed through the optimization of reaction conditions and investigation of the effect of the electronic nature of diphenylacetylene monomers on the polymerizability. The detailed structures of the polymers have been suggested by mass spectrometric analysis of the obtained polymers and oligomers, which suggested that a phenyl group of tetraphenyltin has been introduced to an initiating end of the polymer chain. Mass spectrometric analysis also provided information about the termination processes of the polymerization. The experimental results strongly suggested that the polymerization of diphenylacetylenes using tungsten(VI) chloride and tetraphenyltin proceeds through a migratory insertion mechanism rather than the long-accepted metathesis mechanism.

The present subject matter relates to compositions containing and synthesis of fluorescent materials e made from tetraphenylethylene (TPE) derivative compounds exhibiting aggregation induced emission (AIE) properties. Further contemplated herein are applications for TPE derivative compounds such as electroluminescent devices since they have a high efficiency, low turn on voltage, and excellent brightness. Additionally, application of TPE derivatives exhibiting AIE properties in various fields such as OLEDs, fingerprinting and forensic technology, and various other biological and industrial sectors are discussed.
