“…The field has been successively reviewed, [145][146][147][148] with increasing thoroughness and complexity, sometimes clustering together the discussion of MOFs and fully organic compounds. 149,150 The most successful and widely adopted example of fully organic supramolecular microporous solids is calixarenes. These are polycyclicbenzylethers (or ethers or alcohols), typically adopting a cone formation with functionalisable upper and lower rims (as shown in Fig.…”

Peptide-based solids: porosity and zeolitic behavior

Among the greatest challenges in the field of microporous solids is the development of ''smart'' materials, displaying environment-triggered property tuning. These could be used both in traditional and new applications of microporous materials. In this context, supramolecular peptide-based solids have recently emerged as interesting alternatives to standard microporous solids, such as zeolites and carbon molecular sieves. They possess framework and conformational flexibility, are kinetically stable and reasonably thermally resistant. Important properties such as pore size and inner wall chemistry can be controlled through appropriate chemical modification of the peptide molecules. Peptide-based porous solids have permanent microporosity, often with molecularly sized cavities created by removal of co-crystallised solvent. Some have already been successfully tested as adsorbents and permselective materials, confirming their potential. This review covers the identification, synthesis, characterization techniques and properties of peptide-based microporous solids, discussing their most unique functionalities.

“…Studies on clathrates continue to attract greater attention due to their applications in molecular recognition, separation of isomers [1][2][3][4], synthesis of asymmetric and polymeric compounds [5], purification of gasoline and benzene [6], isolation of branched chain compounds from linear chain hydrocarbons [7], entrapment of organic wastes by coordination clathrates [8], removal of carcinogenic hydrocarbons and preparation of jet fuels [9]. The cavities of clathrates could be engineered to obtain stereoselectivity of the guest molecules [3].…”

The clathrates of Hofmann-(en)2-Td-type, M(en)2M’(CN)4.Aniline (M=Cu,Cd; M’=Cd,Zn) and their hosts were synthesized with the confirmation using FTIR spectra. Hydrogen bonding interaction between π-cloud of phenyl ring of the guest molecule and ethylenediamine(en) of the host lattices was deduced from the upward shift in ν(CH)out of plane bending mode of aniline. A second type of hydrogen bonding between C≡N group of the host lattice and NH2 of aniline guest was also inferred from the downward shift in ν(C≡N) of the clathrates. The relative strength of H-bonding in the clathrates was found to be Hofmann-(en)2-Type > Hofmann-(en)2-Td-Phenol > Hofmann-(en)2-Td-Aniline. The presence of major peaks corresponding to various modes of guest aniline, ligand en and cyanide group in FT Raman spectra also confirms the formation of clathrates. Attempts to synthesize Ni(en)2M’(CN)4.Aniline (M’=Cd,Zn) resulted in the formation of M’(en)2Ni(CN)4.2Aniline (M’=Cd,Zn) due to the exchange of metal ions and greater stability of Ni(CN)4 unit.
