Recent progress on the anticorrosion activities of acridine and acridone derivatives: A review

Corrosion protection properties of tetraphenylethylene-based inhibitors toward carbon steel in acidic medium

“…10–17 In general, conventional corrosion inhibitors are organic compounds containing hetero atoms (O, N, S, or P) and aromatic rings or long alkyl chains, for example, imidazole, pyrimidine, triazole, guanidine, acridine, Schiff-bases, etc. 9,18–22 Particularly, inhibitor molecule with a relatively larger hydrophobic and conjugated skeleton could resist corrosion more effectively, in terms of surface coverage and electron donor–acceptor interaction with metal atoms. 23–26…”

“…It's estimated that 20-30% of corrosion losses could be avoided if adequate protective measures are adopted. 9,10 Currently, the usage of corrosion inhibitors is one of the most practical and cost-effective methods in industry. Corrosion inhibitors can be adsorbed onto metal surface, forming a protective layer that isolates metal surface from corrosive species.…”

[23][24][25][26] Tetraphenylethylene (TPE) bearing a central olen and four peripheral phenyl rings, is a well-known and widely studied AIEgena luminogen possessing the unique character of aggregation-induced emission (AIE).…”

Experimental and theoretical study of tetraphenylethylene-based dicationic compounds for corrosion inhibition of steel and brass in an acidic medium

“…9,10 Metal corrosion cannot be absolutely avoided, but the corrosion rate could be decelerated by corrosion protection methods, and 20%–30% of corrosion losses could be saved if long-term corrosion protection measures are adopted. 11,12 Generally, the use of corrosion-resistant materials, cathodic protection, anti-corrosion coatings, and corrosion inhibitors are common ways to combat corrosion. 13,14 Among the possible strategies, the utilization of corrosion inhibitors is the most prevalent and cost-effective method in the oil and gas industry.…”

“…Conventional corrosion inhibitors are organic compounds containing heteroatoms and aromatic rings or long alkyl chains, for instance, imidazole, pyrimidine, triazole, guanidine, imidazoline, and Schiff bases. 11,[15][16][17][18][19][20][21][22][23][24][25] Recently, plant extracts, ionic liquids, metal-organic frameworks, and quantum dots have been employed as corrosion inhibitors. 12,[26][27][28][29][30] However, most of the corrosion inhibitors are not universally effective for both steel and brass.…”
