The first unsymmetrically substituted polyfluorene bearing a bulky poly(benzyl ether) dendron and less bulky 3,6-dioxaoctyl groups in the 9-position was designed and synthesized, which gives almost a pure bluish photoluminescence with negligible weak greenish excimer emission around 520 nm even in a thermally annealed thin solid film.
我们设计并合成了第一种非对称取代的聚芴,这种聚芴在 9 位上带有笨重的聚(苄基醚)树枝状基团和不太笨重的 3,6-dioxaoctyl 基团,即使在热退火的固体薄膜中,它也能发出几乎纯净的蓝色光致发光,在 520 纳米附近只有微弱的绿色准分子发射,可以忽略不计。
