Synthesis and crystal structure of hydroxyacetophenone Schiff bases containing propargyl moiety: Solvent effects on UV–visible spectra

Water-soluble pyridine-based colorimetric chemosensor for naked eye detection of silver ions: design, synthesis, spectral and theoretical investigation

“…The selected bond lengths and angles are given in Table S2. 29 The molecular conformation of (L) is stabilized by an intra-molecular O1-H/N1 hydrogen bond (2.5 A), generating an S(6) motif. The unit cell packing diagram of (L) viewed along the C axis is shown in Fig.…”

Synthesis, crystal structure and DFT studies of a dual fluorescent ketamine: Structural changes in the ground and excited states

“…This validates the existence of both ketamine and enolimine forms in the ground state. The band appeared around 485 nm may be due to the ketamine form and that at 367 nm corresponds to the enolimine form [39]. The absorption spectra of the KHB form computed match with the experimental absorption spectra indicates that L is in the ketamine form.…”

“…S5). In polar aprotic solvents, the band at 385 nm is bathochromically shifted with respect to chloroform indicates that L is more stabilized in the excited state [39]. In polar protic solvents this band is hypsochromically shifted indicates that L is more stabilized in the ground state (Table 3) (Table 4).…”

“…The N2 -C37 bond length is shifted as 1. From the graph, it is clear that there is some interaction between L and solvent molecules [39,41].…”

Visible‐Light‐Enhanced Photocatalytic Activities for Degradation of Organics by Chromium Acetylacetone Supported on UiO‐66‐NH2

“…[29] This band is commonly observed in ohydroxyl Schiff bases and based on strong intramolecular hydrogen bonding between the hydroxyl group of the salicylidene and the azomethine nitrogen. [30,31] Besides, the results of band gaps are shown in Figure S2. The band gaps of UiO-66-NH 2 , Cr/UiO-66-NH 2 , UiO-66-NH 2 -SA and UiO-66-NH 2 -SA-Cr ( Figure S2) estimated from the intercept of the tangents to the plots were 2.15, 2.13, 1.99, 1.83 eV, respectively.…”
