molecular-based functional materials with opticalproperties. Here, we report on the linear and non-linear opticalproperties of a fluorene-derived dipolar system (DS) and its octupolar analogue (OS) in which donor and acceptor groups are connected by a phenylacetylene linkage as strategy to increase the number of delocalized electrons in the pi-conjugated system. The opticalnonlinear response was analyzed in detail
A new synthetic procedure for the production of symmetricallysubstituted 1,3,5-triazines by cyclization from aromatic nitriles in the molten state with zinc chloride as a catalyst has been developed and applied for a number of aromatic and fluoro aromatic nitriles. The new triazine 8 [2,4,6-tris(4′-bromobiphenylyl)-1,3,5-triazine] is shown to form channel-type inclusion compounds with several aromatic
Recently, thermallyactivated delayed fluorescence (TADF) materials have received increasing attention as effective emitters for organic light‐emitting diodes (OLEDs). However, most of them are usually employed as dopants in a host material. In this report, carbazoledendrimers with a triphenyl‐s‐triazine core are reported, which are the first solution‐processable, non‐doped, high‐molecular‐weight
New solution processable and laminatable terminal modified carbazole-triazine thermallyactivateddelayedfluorescence (TADF) dendrimers are reported. An OLED device with external quantumefficiency of up to 9.5 % at 100...
