Quinolone based chemosensor for the naked-eye and spectrophotometric detection of Cu2+ in aqueous media

AIE active fluorescent organic nanoparticles based optical detection of Cu2+ ions in pure water: a case of aggregation–disaggregation reversibility

“…Herein, we have thoroughly reviewed the literature and constructed a sensor information table (Table 1) highlighting the basic features of the fluorescent detection of Cu 2+ ions in 100% aqueous medium from the reported literature. 34–44 There are only a few articles that present the dual-mode detection of Cu 2+ ions in 100% aqueous medium. In addition, none of the chemosensors contained a pyrene backbone.…”

Recent Advances in One-Pot Modular Synthesis of 2-Quinolones

“…While a number of naturally occurring derivatives have been released, early reports revealed hybrid compounds that are derived from an isoprene unit and quinolones, namely hemiterpenoids [ 35 , 38 , 39 , 40 , 41 , 42 , 43 ]. Selected recent examples are presented in Figure 1 C. Besides biological applications, 2-quinoline scaffolds are found in functional organic materials ( Figure 1 D) [ 44 , 45 , 46 , 47 , 48 , 49 ]. Due to the intrinsic photoactive physical properties of the conjugated system and N , O -based ligating ability, 2-quinolones could be utilized as cationic metal–sensors [ 45 , 46 , 47 ], luminescent materials [ 44 ], and fluorescent small molecule pH probes [ 45 ].…”
