Kyushin, Soichiro;Fujii, Hidetoshi;Negishi, Keisuke;Matsumoto, Hideyuki research published 《 Improvement of the fluorescence quantum yield of triphenylene by the rotational effect of 4-(trimethylsilyl)phenyl groups》, the research content is summarized as follows. The fluorescence quantum yield of triphenylene is low because the transition moment between the HOMOs and the LUMOs is negligibly small. To improve the fluorescence quantum yield, break of the sym. structure of triphenylene is necessary. We found that the rotational effect of the 4-(trimethylsilyl)phenyl groups of 2,3,6,7,10,11-hexakis[4-(trimethylsilyl)phenyl]triphenylene is effective to break the symmetry in spite of the sym. structure, leading to improvement of the fluorescence quantum yield.
SDS of cas: 19111-87-6, 2-Bromotriphenylene is a useful research compound. Its molecular formula is C18H11Br and its molecular weight is 307.2 g/mol. The purity is usually 95%.
2-Bromotriphenylene is a brominating agent that has the ability to react with sodium carbonate and emit light. The luminescence of 2-bromotriphenylene can be used as an indicator of the degree of dilution, or how much water is present in a solution. It also emits light when it reacts with chloride ions in a reaction solution. 2-Bromotriphenylene can be used as a polymer matrix to form polymeric films, which are then used as catalysts for organic reactions. The luminescence properties of 2-bromotriphenylene make it suitable for use in functional theory experiments. This chemical compound is relatively low cost, and has been shown to have high yield in catalysis., 19111-87-6.
