The present invention relates to a 2,2'-(2,8-bis(dialkyl amine)-indeno [1,2-b] fluorenes-6,12-diylidene)-dimalononitrile derivative as shown in a formula I, and a preparation method and use. The compound provided by the present invention as shown in the specification is a near-infrared absorbing organic small molecule semiconductor material, which can be used as an active layer of a bipolar organic field effect transistor, an active layer of a near-infrared light detector and other optoelectronic devices.
Unexpected Rearrangement of 2-Bromoaniline under Biphasic Alkylation Conditions
Barraza, Scott J.,Denmark, Scott E.
supporting information, p. 2891 - 2895 (2017/10/06)
Alkylation of 2-bromoaniline with benzyl bromide under ostensibly basic N-alkylation conditions resulted in migration of bromine from the 2- to the 4-aryl position. Herein we report our studies to elucidate the mechanism of this rearrangement with the objective of suppressing this unexpected outcome. We find that careful choice of reagents is critical, and that this behavior may be extrapolated to alkylation reactions of electron-rich bromo- and iodoanilines in general.

A curable liquid formulation containing at least (i) one or more near-infrared absorbing triphenylamine -based dyes, and (ii) one or more casting solvents. The invention is also directed to solid near- infrared absorbing films composed of crosslinked forms of the curable liquid formulation. The invention is also directed to a microelectronic substrate containing a coating of the solid near-infrared absorbing film as well as a method for patterning a photoresist layer coated on a microelectronic substrate in the case where the near-infrared absorbing film is between the microelectronic substrate and a photoresist film.

N-Metallation of bromoanilines with ethylmagnesium bromide followed by a reaction with trimethylchlorosilane provided N-mono and N-bis(trimethylsilyl) bromoanilines depending on the structure of substrate. The metallation of bissilylated bromoanilines with butyllithium permitted the introduction of a trimethylsilyl substituent in the aromatic ring. Previously unknown 2-bromo-N,N-bis(trimethylsilyl)aniline, 2,6-dibromo-N-trimethylsilylaniline, 2,6-dibromo-N,N-bis(trimethylsilyl)aniline, 2-bromo-6-trimethylsilylaniline, 2-bromo-6-trimethylsilyl-N,N-bis(trimethylsilyl)aniline, 2-bromo-6- trimethylsilyl-N-trimethylsilylaniline, 2,4,6-tribromo-N-trimethylsilylaniline, and 2,4,6-tribromo-N,N-bis(trimethylsilyl)aniline were prepared. The structures of the compounds obtained were established by the chromato-mass spectrometry and 1H, 13C, and 29Si NMR spectroscopy.
