Cathodic electrochromic compound used in electrochromic device, and preparation method thereof

The structural formula of a cathodic electrochromic compound is shown in the description, a pyridine ring in the middle of the cathodic electrochromic compound is connected to any carbon atom in pyridine rings at two sides through a C-C bond; and in the formula, R1 is selected from C2-20 alkyl groups, R2 to R12 are substituent groups on carbon atoms and are respectively independently selected from H, C1-50 alkyl groups, cycloalkyl groups, polycycloalkyl groups, aryl groups, heterocycloalkyl groups, aralkyl groups and alkaryl groups which are free from or contain halogen, N, O, S, Si, P or an unsaturated bond, and X is selected from a methylbenzenesulfonate anion, a tetrafluoroborate anion, a hexafluoroborate anion, a perchlorate anion, a bisoxalatoborate anion, an oxalyldifluroborate anion, a bis(trifluoromethanesulphonyl)imide anion and a tris(trifluoromethanesulfonyl)methyl anion. An electrochromic device using the compound has a long service life and a deep color, and can greatly reduce the visible light transmittance in the power-up state.

A versatile method for suzuki cross-coupling reactions of nitrogen heterocycles

(Chemical Equation Presented) A wide-ranging study of Suzuki reactions which use nitrogen-containing heterocycles is described (see scheme; dba = dibenzylideneacetone, Cy = cyclohexyl). This method is highly versatile (a single procedure was used for all substrates, including boronate esters and trifluoroborates), compatible with a variety of unprotected functionalities (e.g., NH2-and OH-substituted substrates), and efficient even with unactivated aryl chlorides.
