Spectral regression and correlation coefficients of some benzaldimines and salicylaldimines in different solvents

Substituent effect on spectral and antimicrobial activity of Schiff bases derived from aminobenzoic acids

“…This is consistent with earlier reports that indicate that this highly intense π − π band is sensitive to substitution in the aromatic part of the molecule and is little influenced by changing solvent polarity [14]. However, for 1 and 3 the band is solvent dependent with the more polar solvent, DMF having highest value of λ max .…”

Cell permeable fluorescent colorimetric Schiff base chemoreceptor for detecting F− in aqueous solvent

“…S5, Supporting information). The band at 300 nm can be assigned to п-п* and the band at 330nm to n-п* transition of the п electron localized on azomethine group (C=N) [47][48][49]. With gradual addition of F - (Fig.…”

Colorimetric ‘turn on TBET’ sensors for ‘on the spot’ visual detection of HSO4− in semi-aqueous medium: Experimental and quantum chemical (DFT) studies

“…The strong hydrogen bonding may lead to an enhancement of -electron circulation in the aromatic indole moiety, which attenuates the electronic properties of the chromophore, resulting in a significant color change. 22 Upon addition of other anions to R1, only a decrease in intensity of the absorption was observed (Fig. 1c).…”
