2-Phenyl-1,3-butadiene was polymerized using an amidino N-heterocyclic carbene lutetium bis(alkyl) precursor in high 3,4-selectivity (96.9%) and a living mode to afford a new plastic polydiene with a high Tg of 56.1 °C.

Phase Selectivity

All solid solutions (EuxY1−x-PTC, x = 0.013–0.82) are isomorphic to Eu-PTC, but different from Y-PTC, and show phase selectivity as well as excitation wavelength dependent emission.
