“…Therefore, the detection limit of SBA-15/ APTES-NH is 1.49 mM, which indicates that the SBA-15/ APTES-NH is potentially used for detection of Fe 3+ ions even in the lower concentration. Otherwise, the SBA-15/ APTES-NH sensor can be potentially applied to detect Fe 3+ ions in the environmental and pharmaceutical fields [58,59]. Moreover, limit of quantification (LOQ) can be also calculated with the equation of LOQ = 10 SD/K sv [60].…”

N’-(5-nitro-2-oxoindolin-3-ylidene) thiophene-2-carbohydrazide (NH) was successfully synthesized as a ligand, then grafted onto the surface of mesoporous silica SBA-15via an aminopropyl bridge. The successful grafting of ligand NH onto the hybrid nanomaterial (SBA-15/APTES-NH) was confirmed by infrared spectroscopy. On excitation at 276 and 370 nm, the ligand NH and the hybrid nanomaterial SBA-15/APTES-NH showed a strong and narrow emission peak centered at 533 nm. By dispersing SBA-15/APTES-NH in an aqueous solution containing metal ions, the resulting solid materials showed a higher binding of NH sensing site to Fe3+ ions as compared to the others with a quench of the emission intensity up to 84%. This result showed that the hybrid nanomaterial is a potential chemosensor that requires development for the detection of metal ions.

“…They are soluble only in aprotic polar solvents, such as N-methyl-2-pyrrolidone, N,Ndimethylacetamide, N,N-dimethylformamide or dimethyl sulfoxide (SI, Sections S5). The average molecular mass of P1 and P2 was Mw = 6.4×10 4 and Mw = 4.5×10 4 , respectively, and the intrinsic viscosities [η] = 1.18 dL•g -1 and [η] = 0.95 dL•g -1 , respectively.…”

“…In this regard, there are a very few examples of chemosensors were reported based on quinazolinone moiety. One such example is 2‐(1,3‐thiazol‐2‐yl)‐2,3‐dihydroquinazolin‐4(1H)‐one ( 39 ), which was prepared as shown in Scheme , that exhibits high sensitivity and selectivity for ferric ions (with detection limit 0.0366 μg mL −1 ) over other biologically and environmentally relevant metal ions in terms of fluorescence properties and further reversibility by the addition of EDTA …”

Even though several quinazolinone derivatives have been synthesized, still there is a constant demand for designing and synthesis of new quinazolinone derivatives by fine‐tuning the electronic and steric properties of substituents due to their interesting structure‐based biological utilities and the versatile chemistry. While many of the synthetic routes are useful as building blocks in synthetic organic chemistry, the drawbacks of some of these methods like unsatisfactory or variable yields, prolonged reaction times, inadequate tolerance to other substrates, including the use of costly catalysts/reagents. This review article is mainly focused on various synthetic routes for the preparation of quinazolinones, their important properties and applications.
