This communication reports that not only the emission colour but also the photoluminescence quantum yield of Alq3 can be tuned by introducing fluorine atoms at different positions; with fluorination at C-5 the emission is red-shifted with a tremendously decreased intensity, fluorination at C-6 causes a blue-shift with a significantly increased intensity, and fluorination at C-7 has a minor effect on both the colour and intensity of Alq3's emission.
本通讯报道，不仅Alq3的发射颜色，而且其光致发光量子产率都可以通过在不同位置引入氟原子来调节；在C-5处氟化时，发射光红移且强度大幅降低，在C-6处氟化导致蓝移且强度显著增加，而在C-7处氟化对Alq3发射光的颜色和强度影响较小。
