Smart Fluorescent Dyes: Modulating photo- and electroluminescence in a stimuli-responsive molecular dye
(World News Science)

Controlling the excited electronic states in luminescent systems remains a challenge in the development of fluorescent and phosphorescent dyes. Now, scientists in Japan have developed a unique organic fluorophore that changes its emission color without loss of efficiency when externally stimulated. The study published in the journal Angewandte Chemie explains this behavior by a simple phase transformation of the solid substance, which could be relevant for optoelectronic applications such as in smart OLEDs. Although luminescence is an extensively studied phenomenon and its theoretical basis is well understood, the development of new pigments...
