Poly(3,6-silafluorene-co-2,7-fluorene)-based high-efficiency and color-pure blue light-emitting polymers with extremely narrow band-width and high spectral stability

Highly efficient and pure-blue light-emitting copolymers of poly(3,6-silafluorene-co-2,7-fluorene) were synthesized, which show a quantum efficiency of 3.34% and a luminous efficiency of 2.02 cd A-1 at a practical brightness of 326 cd m-2 with CIE 1931 chromaticity coordinates of (0.16, 0.07).
