Abstract
We evaluated the performance of a red microfluidic electrogenerated chemiluminescence (ECL) device using tetraphenyldibenzoperiflanthene (DBP) as a fluorescent guest. 5,6,11,12-Tetraphenylnaphthacene (rubrene), which is a well-known yellow fluorescent material, was used as a host molecule and dissolved in an organic solvent with the guest. The microfluidic ECL device with the DBP-doped rubrene solution exhibited a bright red emission originated from DBP with a maximum luminance of 62.0 cd/m2 at a direct current voltage of 5.5 V. By contrast, when the rubrene host was absent from the solution, the ECL emission of DBP was found to be significantly weak. Electrochemical properties of rubrene and DBP were also evaluated by cyclic voltammetry to discuss the emission mechanism.
