“…The ESIPT-based AIEgens has also been developed and applied to detect other metal ions, including Al 3+ , [31, 33, 37-39, 45, 46, 49] Cd 2+ , [52,57] Hg 2+ , [36,40] Pb 2+ , [45] Fe 3+ , [33,211] and Fe 2+ . [42] The detection of Al 3+ , Cd 2+ , and Pb 2+ follows the same CHEF mechanism as that of Zn 2+ , whereas the detection of Fe 3+ and Fe 2+ follows the same CHEQ mechanism as that of Cu 2+ .…”

“…Some ESIPT-based AIEgens may detect two or more metal ions. [33,37,40,45,46,49,52,57] Typically, the detection of different ions by the same ESIPT-based AIEgen was performed in different solutions. For example, compound 1 can detect Zn 2+ in DMSO/H 2 O (9:1 v/v, 5 μM, HEPES, pH 7.2) mixture solution, whereas it can detect Al 3+ in MeOH/H 2 O (9:1 v/v, 5 μM, HEPES, pH 7.2) mixture solution (see Figure 1C).…”

In this review, we present a systematic and comprehensive summary of the recent development and applications of excited-state intramolecular proton transfer-based (ESIPT-based) aggregation-induced emission luminogens (AIEgens), a type of promising materials that inherit the advantages of ESIPT and AIE, such as large Stokes shift, excellent photostability, and low self-quenching. We first summarize the backbones that have been used to construct the ESIPT-based AIEgens and classify the constructed ones based on the relation between ESIPT and AIE unit. According to the sensing mechanisms and design strategies, we have reviewed the applications of ESIPT-based AIEgens in bioimaging, drug delivery systems, organic lightemitting diodes, photo-patterning, liquid crystal, and the detection of metal cations, anions, small molecules, biothiols, biological enzymes, latent fingerprinting, and so on. We have also reviewed the recent advances in the development of new theoretical methods for investigating molecular photochemistry in crystals and their applications in ESIPT-based AIEgens. We discussed the remaining challenges in this field and the issues that need to be addressed. We anticipate that this review can provide a comprehensive picture of the current condition of research in this field, and promote researchers to make more efforts to develop novel ESIPT-based AIEgens with new applications.

“…These Schiff bases possessed several binding sites which can coordinate metal ions. Complexes with biological activities [14], photophysical [15,16], antimicrobial [17,18], anticancer [19], antitubercular [20] or antiviral [21] properties have been reported. Benzothiazole ligand derivatives can act in diverse modes according to the number of binding sites.…”

“…Compounds containing benzimidazole nucleus demonstrate a wide variety of biological activity properties such as anticancer, antitubercular antimicrobial, antifungal, antioxidant, antidiabetic and etc [1][2][3][4][5][6][7][8][9][10][11][12][13]. On the other hand, heterocyclic benzimidazole derivatives have different application area and can be used as catalysts [14][15][16] and sensors [17,18]. Therefore, benzimidazoles and their derivatives are consumed in large quantities in the chemical, medical and biological industries.…”

Four different benzimidazolium salts (1-4) were prepared in three steps at 80 o C and their structures were elucidated using spectroscopic methods. The compounds (1-4) obtained were tested in in situ medium as catalyst in the carbon-carbon (C-C) bond formation reactions of two different boronic acid derivatives with various aryl halides in the presence of palladium acetate (PdOAc)2 and sodium tertiarybutoxide (NaOBu t) as a base. With this reaction, four coupling products (5-8) were synthesized in different yields ranging from 11 to 93%. Compound 2 from the carbene precursors tested in the Suzuki-Miyaura cross-coupling reaction was found to be a more effective catalyst candidate than others.
