폴리(9,9-디옥틸플루오렌-co-N-(4-부틸페닐)디페닐아민) C화학적 특성, 용도, 생산
개요
Poly(9,9-dioctylfluorene-alt-N-(4-sec-butylphenyl)-diphenylamine) (TFB) is a triarylamine based semiconductor with a band gap of 3 eV (HOMO and LUMO levels of 5.3 and 2.3 eV, respectively) and a relatively high hole mobility of 2 ×10-3 cm2 V-1 s-1.
용도
TFB can be used in the formation of multilayer quantum dot-based light-emitting diodes (LEDs). It can also be used in the fabrication of highly responsive gas sensors for breath analysis.
일반 설명
TFB, a hole transporting material and an electron-blocking layer, has high hole mobility, low electron affinity, and high ionic potential. Its electron blocking nature results in effective confinement of injected charge carriers in the perovskite layers.
