我们提出了电致化学发光(ECL)细胞使用蒽衍生物的主机材料。使用2-叔丁基-9,10-二(萘-2-基)蒽(TBADN)作为ECL主体并溶解在有机溶剂中。参照有机电致发光器件的主客体发光过程,将荧光客体掺杂到宽能隙TBADN主体溶液中。4,4 ′-双[4-(二苯基氨基)苯乙烯基]联苯(BDAVBi)和2,8-二叔丁基-5,11-双(4-叔丁基苯基)-6,12-二苯基并四苯(TBRb)分别用作蓝色和黄色客体发光体。从具有BDAVBi掺杂的TBADN溶液的ECL电池获得蓝色ECL发射。此外,通过使用掺杂有BDAVBi和TBRb的TBADN溶液,成功地展示了具有从405至700 nm的宽波长光谱的白色ECL发射。我们期望所提出的主客体ECL溶液可以为微流体自发射显示应用开辟新的可能性。
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.
