Abstract: A compound represented by the Chemical Formula 1 has a high-density and thus constitutes a dense film structure. Moreover, the compound represented by the Chemical Formula 1 binds to oxygen or moisture, thereby suppressing penetration of oxygen or moisture into the organic light-emitting device. In addition, the organic light-emitting device including a novel compound represented by a Chemical Formula 1 has a low operation voltage and has excellent luminous efficiency, excellent external quantum efficiency (EQE), a long lifetime, and excellent stability.

Abstract: Biologically active compounds and their methods of preparation are provided that may be used as photosensitizers for diagnostic and therapeutic applications, particularly for PDT of cancer, infectious and other hyperproliferative diseases, fluorescence diagnosis and PDT treatment of non-tumorous indications such as arthritis, inflammatory diseases, viral or bacterial infections, dermatological otorhinolanyingology disorders, ophthalmological or urological disorders. As the compounds exhibit also toxicity against targets (tumor cells, bacteria, inflammation-related cells) without light these biologically active compounds may also be used for the light-independent treatment of such indications. Embodiments also include methods to synthesize iridium(III) complex structures incorporating a substituted 2,3,5,6-tetrafluorophenyl-dipyrromethene (2,3,5,6-tetrafluorophenyldipyrrin) unit or a substituted 3-mtrophenyl-dipyrromethene (3-nitroplienyl-dipyrritt) unit. Amphiphilic compounds with increased anti-tumour and anti-bacterial efficacy are also provided. Specifically, this is achieved by substitution with bromine atoms and sugar moieties.

Abstract: Conversion of vegetable-derived triglycerides to fatty acid methyl esters (FAMEs) is a popular approach to the generation of biodiesel fuels and the basis of a growing industry. Drawbacks of the strategy are that (a) the glycerol backbone of the triglyceride is discarded as waste in this synthesis, and (2) many natural triglycerides are multiply-unsaturated or fully saturated, giving inferior performance and causing engine problems with long-term use. Here, we show that catalysis by iridium complex 1 can address both of these problems through selective reduction of triglycerides high in polyunsaturated fatty esters to FAMEs with high oleate concentration. This is realized using hydrogen imbedded in the triglyceride backbone, concurrently generating lactate as a value-added C3 product. Additional methanol or glycerol as a hydrogen source enables reduction of corn and soybean oils to >80% oleate.
