Nitrogen Doping of Graphite Oxide with 2,3‐Diaminomaleonitrile: A Study of the Structural, Morphological, and Electrochemical Behavior

“…All, these defined molecules have architectures and matrix scaffolds with prearranged functionalities. [ 14 ] Using a microwave reactor for the reaction between 2,3‐diaminomaleonitrile with trifluoroacetic acid, cyanotrifluoromethylimidazole carboxamide was obtained. Also, the reaction of 2,3‐DAMN with different acid chlorides R‐COCl (where R═CH 3 , C 6 H 5 —, C 6 H 4 —CH 3 —p, C 6 H 4 —Cl—p, 1‐napthyl‐, and 2‐naphthyl‐) in the presence of triethylamine (catalyst) takes a few minutes, where the products formed are 4‐cyano‐2‐substituted‐1 H‐imidazole‐5‐carboxamide with different R‐ from the substituents previously used, reaching 80%–88% yield.…”

A novel donor–π–acceptor halochromic 2,6-distyrylnaphthalene chromophore: synthesis, photophysical properties and DFT studies

“…[1][2][3][4][5][6] On the other hand, organic molecules that possess intramolecular charge transfer (ICT) character are important in a large number of areas, such as organic solar cells, polarity probes and nonlinear optics. 7,8 Donor-p-acceptor (D-p-A; where D is an electron-donating group, A is an electron-accepting group, and p is a conjugating moiety) systems with different congurations have been extensively developed because their absorption spectra and energy gaps can be readily tuned by controlling the ICT character using different electron-donor and electron-acceptor groups. This belonging plays an important role in the improvement of the photophysical properties of photonic devices.…”

Synthesis Efforts of Acyclic Bis(monoalkylamino)maleonitriles and Macrocyclic Bis(dialkylamino)maleonitriles as Fluorescent Probes for Cations and a New Colorimetric Copper(II) Chemodosimeter

“…Nowadays, on the basis of the diaminomaleonitrile unit highly cation or anion selective colorimetric or fluorometric indicators were developed (Cu 2+ , [5–11] Hg 2+ , [12] Mn 2+ , [13] Zn 2+ , [13] Al 3+ , [14,15] Cd 2+ , [16] Fe 3+ , [17] F − , [18,19] OCl −[20–22] or CN −[23,24] ). Overall, diaminomaleonitrile based probes are suitable tools to detect cations or anions selectively [25] …”
