Electron Transport Layer Material with Triazine Core
Electron deficient semiconducting material for developing highly efficient exciplex OLEDs
Product Information | Device Structures | MSDS | Literature | Related Products | Technical Support
CN-T2T has a triazine core and three [1,1'-biphenyl]-3-carbonitrile side groups that attached to the core at 2,4-6-positions. Being electron deficient, CN-T2T is either used as electron transport layer material or as electron acceptor with electron donating materials such as BCzPh and Tris-PCz to form exciplexes for developing highly efficient exciplex OLEDs.
An efficient deep-red phosphorescent OLED using a TCTA:CN-T2T exciplex system as the host and a red-emitting Ir(piq)2acac and a deep-red Ir(fliq)2acac double emitting layers achieved high peak efficiency of 19.1% (10.2 cd/A and 13.8 lm/W) and a power density of 5 mW/cm2 with low operating voltage of 5.2 eV.
A yellow OLED device with exciplex cohost of MS-OC:CN-T2T and PO-01 as dopant achieved the highest efficiency among the tested yellow-emitting OLEDs, having a luminance efficiency of 80.0 cd/A, power efficiency of 113.0 lm/W, low turn-on voltage of 2.1 V, high maximum luminance of 142,464 cd/m2, and peak EQE of 27.1% [1]
