Abstract

A hole-transporting material, N1,N1,N3,N3-tetra([1,1′-biphenyl]-4-yl)-N5,N5-diphenylbenzene-1,3,5-triamine (TDAB-BP), was synthesized by di([1,1′-biphenyl]-4-yl)amine and 3,5-dichloro-N,N-diphenylaniline via Buchwald–Hartwig coupling reaction. The material exhibit high hole mobility, excellent thermal and morphological stability. TDAB-based OLED device exhibited the highest performance in terms of the maximum current efficiency (9.34 cd/A), maximum power efficiency (5.89 lm/W), and maximum external quantum efficiency (6.61%), which is significantly improved than that of the standard device based on 4,4′-bis[N-(1-naphthyl)-N-phenyl-amino]-biphenyl (NPB) (7.12 cd/A, 4.90 lm/W and 5.31%). Furthermore, TDAB-BP shows a higher decomposition temperature (Td) of 505 °C than that of NPB (418 °C). This material could be a promising hole-transporting material, especially for the high-temperature applications of OLEDs and other organic electronic devices.

Abstract

A novel probe (1) based on flavone was synthesized and used for the detection of hydrazine in a mixture of phosphate buffer saline (PBS, pH 7.0, 20 mM) and DMSO (1/9, v PBS /v DMSO ) at room temperature. The limit of detection is 0.15 μM (4.8 ppb), which is lower than the U.S. Environmental Protection Agency standard (10 ppb). Notably, probe 1 could be used for gas state discrimination of hydrazine with different concentrations through color changes from readily prepared strips. Additionally, probe 1 could also be applied for the imaging of hydrazine in living cells.
