Summary

New organogels formed from tetranitrodibenzocrown ethers and chloroalkanes exhibit fibrous structures. These gels facilitate the supercooling of chloroform and liquefy at 307 K.

Area of Science:

  • Supramolecular Chemistry
  • Materials Science

Background:

  • Dibenzocrown ethers are known for their complexation abilities.
  • Organogelation is a significant area in materials science for developing novel soft materials.

Purpose of the Study:

  • To investigate the organogelation properties of 3,3',4'4'-tetranitrodibenzocrown ethers (TNDB24C8 and TNDB30C10) with chloroalkanes.
  • To characterize the supramolecular structure and thermal properties of the resulting organogels.

Main Methods:

  • Organogel formation using TNDB24C8 and TNDB30C10 with chloroalkanes at 3% w/v.
  • Microscopy techniques including Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) for structural analysis.
  • Differential Scanning Calorimetry (DSC) to study thermal transitions and gel-sol behavior.

Main Results:

  • Both TNDB24C8 and TNDB30C10 successfully formed organogels with chloroalkanes at 3% w/v.
  • AFM and SEM revealed fibrous superstructures, with gels formed using TNDB30C10 and chloroform exhibiting more pronounced fibrous and elongated domains.
  • DSC indicated that the organogel aids in the formation of supercooled chloroform (ΔT = 21 K) and that the gel-gel transition occurs at 307 K.

Conclusions:

  • 3,3',4'4'-tetranitrodibenzocrown ethers are effective gelators for chloroalkanes.
  • The supramolecular architecture of the organogels, characterized by fibrous networks, influences their properties.
  • The developed organogels demonstrate potential in applications requiring controlled phase transitions and stabilization of metastable states, such as supercooled liquids.
