Specifications | MSDS | Literature and Reviews


4-Butyl-N,N-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane-4-phenyl)aniline, CAS number 444289-55-8, produced normally from 4-bromo-N-(4-bromophenyl)-N-(4-butylphenyl)aniline reacting with bis(pinacolato)diboron, is a convenient building block used for the preparation of semiconducting conjugated polymers as emitting layer, phosphorescent host or hole transport layer materials in application of OLED and perovskite solar cells devices. A typical example of such materials is polyTPD which is widely used as hole transport layer in such devices.

π-conjugated polymer poly(triphenylamine-carbazole) (PTC-U), mimicking a DNA in structure, exhibits high thermal stability, excellent hole injection and electron-blocking abilities in films owing to the uracil induced physical cross-linking.

A fluorene and triarylamine back-boned copolymer PFA-OXD shows bipolar charge transporting functionalities by incorporating electron-deficient oxadiazole pendent groups onto the C9 position of the fluorene repeating units. A high-brightness, highly efficient red electroluminescent device having a maximum brightness of 28, 440 cd m-2 was further demonstrated by doping PFA-OXD with a red-emitting phosphorescent dye, Os(fppz).
