Optimizing the optical and biological properties of 6-(1H-benzimidazole)-2-naphthalenol as a fluorescent probe for the detection of thiophenols: a theoretical study

Abstract

The study presents the influence of structure modulation by introduction of selected donor and acceptor substituents on the properties of 6-(1H-bezimidazole)-2(2,4-dinitrobenzenesulfonate)naphthalene used in thiophenol identification.

Synthesis and comparative solvatochromic studies of novel Mono azo ureido/thioureido benzimidazole dyes

“…Benzimidazoles are the corner stones as intermediates in many organic reactions (Bai et al , 2001; Hasegawa et al , 1999), important synthons for modeling many biological systems (Erhardt, 1987; Gravatt et al ,1994; Jayabharathi et al , 2013; Khalifa, 2020; Khalifa et al , 2019; Roth et al , 1997) and in supramolecular host-guest systems for Nanomedicine (Praveen and Babu, 2019; Wu et al , 2015). Their characteristic optical linear (Praveen et al , 2015) and second-order non-linear properties (Batista et al , 2007) have been studied and could to be boosted by planting hydroxyl and/or alkoxy substituents (Krawczyk, 2020). The excited state intramolecular proton transfer in these aromatic molecules leads to many fabulous applications such as photo (UV) stabilizers (Franciscato Campo et al , 2006; Ragno et al , 2006; Xu et al , 2019), selective fluorescent biological probes (Xiong et al , 2014), dye sensitizers in solar cells (Bodedla et al , 2016), laser dyes (Yang et al , 2014) and host materials for phosphorescent emitters (Karthik et al , 2016).…”
