“…The N 1s XPS spectrum can be tted into three peaks with the binding energy peaks at 397.1, 398.1 and 399.9 eV due to the R2NH, RNH 2 and R3N groups, respectively. 20 The oxygen-containing groups were determined by the O 1s XPS spectra. These could be tted into two peaks with the binding energy at 531.1 and 532.2 eV, which were attributed to the C]O and C-O groups.…”

“…13 The introduction of aldehyde groups on the cellulose molecular chain makes dialdehyde cellulose easy to further functionalize. The dialdehyde cellulose composite materials can be obtained by Schiff base reaction, [14][15][16][17] cationization reaction, 18 and carboxylation reaction. 19 The composite materials have been increasingly applied in the field of analytical chemistry.…”

A novel high‐performance liquid chromatography (HPLC) multifunctional immobilized chiral stationary phase was prepared by bonding dialdehyde microcrystalline cellulose to aminosilica via Schiff base reaction and then derivatized with 3,5‐dimethylphenyl isocyanate. The HPLC multifunctional immobilized chiral stationary phase could not only achieve chiral separation but also achieve achiral separation. Chiral separation evaluation showed that 1‐(1‐naphthyl)ethanol and mandelonitrile got separation in normal phase (NP) mode. Ranolazine, benzoin ethyl ether, metalaxyl, and diclofop were successfully separated in reversed phase (RP) mode. Aromatic compounds such as polycyclic aromatic hydrocarbons (PAHs), anilines, and aromatic acids were selected as analytes to investigate the achiral separation performance of the multifunctional immobilized chiral stationary phase in NP and RP modes. The achiral separation evaluation showed that six PAHs could get good separation within 10 minutes in NP mode. Four aromatic acids were well separated in RP mode. The retention mechanism of aromatic compounds on the stationary phase was discussed, founding that π‐π interaction, π‐π electron‐donor‐acceptor (EDA) interaction, and hydrogen bonding interaction played important roles during the achiral separation process. This multifunctional immobilized chiral stationary phase had the advantages of simple bonding steps, short reaction time, and no need for space arm.

“…The high reactivity of the aldehyde groups makes the DAC easy to functionalize, especially through the Schiff base reaction with the amino reagent to prepare the DAC composites. [32][33][34][35] As a chiral selector, DAC has been applied as HPLC CSPs, which proves that DAC has both chiral and achiral separation ability. 36 Cyclodextrins are one of the most commonly used chiral selectors in HPLC for enantioseparation 37,38 due to their ability to form host-guest inclusion with a large variety of chiral compounds.…”

A novel biselector bonded‐type multifunctional chiral stationary phase (MCSP) was prepared by covalently crosslinking dialdehyde cellulose (DAC) with 6‐monodeoxy‐6‐monoamino‐β‐cyclodextrine (CD) via Schiff base reaction. The biselector bonded‐type MCSP had good chiral and achiral chromatographic performance in normal phase (NP) and reversed phase (RP) modes. Seven and eight enantiomers were successfully separated on the prepared biselector bonded‐type MCSP in NP and RP modes, respectively. The biselector bonded‐type MCSP showed enhanced chiral resolution ability compared with single selector chiral stationary phases due to the simultaneous introduction of DAC and 6‐monodeoxy‐6‐monoamino‐β‐CD on the surface of silica gel. Aromatic compounds including polycyclic aromatic hydrocarbons, anilines, phenols, phenylates, and aromatic acids were choosed as analytes to investigate the achiral chromatographic performance of the biselector bonded‐type MCSP in NP and RP modes. Chromatographic evaluation results showed that the above aromatic compounds were essentially capable of achieving baseline separation by hydrophobic interaction, π‐π interaction, and π‐π electron‐donor‐acceptor interaction. Moreover, the host‐guest inclusion effect of 6‐monodeoxy‐6‐monoamino‐β‐CD and the multiple interactions made the biselector bonded‐type MCSP have good steric selectivity. The preparation method of the biselector bonded‐type MCSP was simple and provided a new idea and strategy for the preparation of the subsequent novel biselector MCSP.
