Abstract

We proposed electrogenerated chemiluminescence (ECL) cells using an anthracene derivative host material. 2-tert-Butyl-9,10-di(naphth-2-yl) anthracene (TBADN) was used as an ECL host and dissolved in an organic solvent. By reference to electroluminescent process of organic light-emitting diodes using a host-guest emitting layer, fluorescent guests were doped into a wide-energy-gap TBADN host solution. 4,4′-Bis[4-(diphenylamino)styryl]biphenyl (BDAVBi) and 2,8-di-tert-butyl-5,11-bis(4-tert-butylphenyl)-6,12-diphenyltetracene (TBRb) were used as blue and yellow guest emitters, respectively. A blue ECL emission was obtained from the ECL cell with the BDAVBi-doped TBADN solution. Furthermore, a white ECL emission with a broad wavelength spectrum from 405 to 700 nm was successfully demonstrated by using the TBADN solution doped with both BDAVBi and TBRb. We expect that the suggested host-guest ECL solutions can open up new possibilities for microfluidic self-emissive display applications.
