Influence of polyhedral oligomeric silsesquioxanes (POSS) on blue light-emitting materials for OLED
摘要:
By using Heck polycondensation, we have synthesized carbazole-based alt-copolymers tethered with polyhedral oligomeric silsesquioxanes (POSS), which had well-defined architectures, similar polymerization degrees and the different contents of POSS. The effect of POSS content and the length of the side chain containing FOSS on the electroluminescence properties of these polymers were investigated. POSS particles in these alt-copolymers showed excellent dispersity and prevented the interchain aggregation of polymers in film state well. Besides, POSS benefited charge balance by increasing the electron current density, which led to a higher luminance and current efficiency, as well as purer blue light-emitting. (C) 2014 Elsevier Ltd.

A series of metal-cluster hybrid materials was successfully fabricated by using the electropolymerization (EP) method. Poly-metal clusters in an extended conjugated network establish an electron transport highway to catalytic sites. The improvement in catalytic performance in poly-metal clusters was demonstrated by electrocatalytic reduction of nitrate (NO3−) to ammonia (NH3) and photocatalytic chemical

family of blockcodendrimers consisting of highly versatile mesogenic and carbazole‐containing 2,2‐bis(hydroxymethyl)propionic acid (bis‐MPA) dendrons are reported. The liquid‐crystal behaviour was investigated by means of differential scanning calorimetry, polarised‐light optical microscopy and X‐ray diffraction. Depending on the chemical structure of the constituent dendrons, the codendrimers show lamellar
