摘要

以五种不同的手性羧酸为共价锚定剂,在λ-磷酸锆(λ-ZrP)片上制备了五种通式为λ-ZrPO4(OH)1-x(RCOO)x(dmso)的新型二维手性材料,即(S)-(+)- mandelic acid (MAN)、(R)-(?)-α-甲氧基苯基乙酸(MPA)、(S)-(+)- ibuprofen (IBU)、(S)-(+)-6-甲氧基-α-甲基-2-萘乙酸(MMN)和(?)- menthyloxyacetic acid (MEN)。采用x射线衍射、红外光谱、元素分析、热重分析和偏振法对合成材料进行了表征。x射线衍射图显示,层间分离从1.02?nm(纯λ-ZrP)至1.31-2.31 ?Nm是上述酸在层间廊内结合的结果。旋光测量结果表明,合成材料具有明显的旋光活性,在手性分离技术领域具有潜在的应用前景。

Novel optically active 2D materials based on λ-zirconium phosphate and chiral monocarboxylic acids: Synthesis and characterization

Five novel chiral 2D materials with general formula λ-ZrPO4(OH)1-x(RCOO)x(dmso) have been prepared by covalent anchoring of five different chiral carboxylic acids to the sheets of λ-zirconium phosphate (λ-ZrP), namely (S)-(+)-Mandelic acid (MAN), (R)-(?)-α-Methoxyphenylacetic acid (MPA), (S)-(+)-Ibuprofen (IBU), (S)-(+)-6-Methoxy-α-methyl-2-naphthaleneacetic acid (MMN) and (?)-Menthyloxyacetic acid (MEN). The synthesized materials were characterized by X-ray diffractometry, FT-IR spectrophotometry, elemental and thermogravimetric analyses and polarimetry. The X-ray diffraction patterns revealed that the interlayer separations increase from 1.02?nm (pure λ-ZrP) to 1.31–2.31?nm as a result of the incorporation of the mentioned acids within the interlayer gallery. The polarimetry measurements showed that the synthesized materials have appreciable optical activities suggesting they could have protentional applications in the field of chiral separation techniques.

期刊介绍: The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
