摘要：

A series of new aggregation-induced emission enhancement derivatives from bis(triphenylethylene) with strong blue-light-emitting properties and high thermal stability have been synthesized Their maximum fluorescence emission wavelengths range between 464-468 nm with fluorescence quantum yields of 0 58-0 88 Their glass transition temperatures range from 125 degrees C to 178 C The obtained experimental results demonstrate the different aggregation-induced emission enhancement phenomena caused by the effect of solvent and formation of both H- and J- aggregation states An emitting device was fabricated using a bis(triphenylene) derivative in the emitting layer which exhibited a luminance efficiency of up to 2 cd/A with a maximum brightness of 548 cd/m(2) (C) 2010 Elsevier Ltd All rights reserved
