Acridine as Bioinspired Corrosion Inhibitors

“…Bromo(methoxy)methane reacts onto the 4 th position and C‐5 position of acridine in the highly acidic environment at 20 °C for few hours to yield either 4,5‐bis(bromomethyl)acridines or 4‐(bromomethyl) acridines which was further exposed to several amendments. [ 20,21 ]…”

“…Bromo(methoxy)methane reacts onto the 4 th position and C-5 position of acridine in the highly acidic environment at 20 °C for few hours to yield either 4,5bis(bromomethyl)acridines or 4-(bromomethyl) acridines which was further exposed to several amendments. [20,21] C-9 position of acridines is very much susceptible to the nucleophilic addition to yield acridanes, which often are rearomatized. Nitrogen atom present at the C-10 position of the acridine ring is also very prone to the nucleophilic addition reaction and can be modified to the alkyl derivatives.…”

Synthesis and investigation on optical and electrochemical properties of 2,4-diaryl-9-chloro-5,6,7,8-tetrahydroacridines

“…NMR data were recorded in CDCl 3 (tetramethylsilane as the internal standard) on Bruker ARX 300 instruments. Signals due to the solvent are: CHCl 3 : δ 7.26 for 1 H and δ 77.16 for 13 C. Peak characterization of 1 H NMR spectra: s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet. Chemical shifts were given in ppm (δ) relative to tetramethylsilane (SiMe 4 ) as internal standard.…”

“…π-Conjugated organic molecules are finding use in numerous areas ranging from organic electronics [1][2][3][4][5], ions sensing [6,7], and solar cell development [8][9][10]. Within this background, acridines represent an interesting class of heteroaromatic π-conjugated compounds [11][12][13][14] which show great perspectives in medicinal chemistry [15][16][17][18][19][20][21][22][23], dye industries [24][25][26], and metal chemo sensing [27][28][29]. More recently, acridines have received growing attention in organic electronics [30][31][32], due to their strong electron-donating ability [33,34] and remarkable optoelectronic properties [32,[35][36][37].…”
