Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons. 3032-92-6, formula is C9H5N, Name is 4-Ethynylbenzonitrile. Nitriles are found in many useful compounds. One of the most common occurrences of nitriles is in Nitrile rubber. Recommanded Product: 4-Ethynylbenzonitrile.
Murayama, Nina;Hao Jorolan, Joel;Minoura, Mao;Nakano, Haruyuki;Ikoma, Tadaaki;Matano, Yoshihiro research published 《 9-(Diphenylphosphoryl)-10-(phenylethynyl)anthracene Derivatives: Synthesis and Implications for the Substituent and Solvent Effects on the Light-Emitting Properties》, the research content is summarized as follows. Herein, we report a series of 9-(diphenylphosphoryl)-10-(phenylethynyl)anthracenes (DPPPEAs) as novel fluorescent 9,10-disubstituted anthracene derivatives The DPPPEAs were prepared by Sonogashira coupling of (10-bromoanthracen-9-yl)diphenylphosphine oxide with terminal arylacetylenes, and their structures were fully characterized. UV/Vis fluorescence spectroscopy and theor. calculations were used to evaluate substituent effects on fluorescence properties of DPPPEAs. The nature of emissive excited state of DPPPEAs was found to vary greatly depending on the substituent, solvent, and temperature Unsubstituted DPPPEA emitted intense fluorescence from locally excited (LE) state, whereas donor-acceptor (D-A) type DPPPEAs substituted with diphenylamino groups showed strong solvatofluorochromism derived from the charge-transfer (CT) state. Notably, carbazolyl derivatives exhibited fluorescence from LE hybridized with CT state. The disappearance of CT emission in rigid media suggests that solvent reorganization plays a crucial role in producing large Stokes shifts of D-A type derivatives The DPPPEAs have also been found to function as annihilators in porphyrin-sensitized triplet-triplet annihilation processes.
