A tetraphenylethene-based red luminophor for an efficient non-doped electroluminescence device and cellular imaging

Abstract

An efficient red luminophor (TTPEBTTD) consisting of a 4,7-di(thiophen-2-yl)benzo-2,1,3-thiadiazole core and tetraphenylethene peripheries is developed. The non-doped electroluminescence device based on TTPEBTTD radiates red light with high efficiency up to 3.7%. The nanoparticles of TTPEBTTD are promising fluorescent visualizers for cellular imaging with low cytotoxicity.
