A new class of bisindole-based red fluorescent materials was prepared and used as non-doping red emitters to give the devices emitting saturated red colour at about 650 nm with a chromaticity coordinate of (x = 0.64, y = 0.34), matching the CIE 1931 standard red color very well.
制备了一类新的双
吲哚基红色荧光材料,并将其用作非掺杂红色发光体,使器件在约 650 纳米波长处发出饱和红色,色度坐标为(x = 0.64,y = 0.34),与 CIE 1931 标准红色非常吻合。
