Chair Conformation of Cyclohexane02:02

Chair Conformation of Cyclohexane

The chair conformation is the most stable form of cyclohexane due to the absence of angle and torsional strain. The absence of angle strain is a result of cyclohexane’s bond angle being very close to the ideal tetrahedral bond angle of 109.5° in its chair conformer. Similarly, the torsional strain is also absent owing to the perfectly staggered arrangement of bonds.
The hydrogen atoms linked to carbons are arranged in two different axial and equatorial orientations to achieve this staggered...
Conformations of Cyclohexane02:11

Conformations of Cyclohexane

Cyclohexane does not exist in a planar form due to the high angle and torsional strain it would experience in the planar structure. Instead, it adopts non-planar chair and boat conformations.
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
Stability of Substituted Cyclohexanes02:30

Stability of Substituted Cyclohexanes

This lesson discusses the stability of substituted cyclohexanes with a focus on energies of various conformers and the effect of 1,3-diaxial interactions.
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...

Area of Science:

  • Nanotechnology
  • Materials Science
  • Supramolecular Chemistry

Background:

  • Bottom-up nanotechnology aims for precise shape control of functional molecules.
  • Fullerene (C60) is a key material for nanoscale applications.
  • Controlling the morphology of C60 assemblies is crucial for advanced functionalities.

Purpose of the Study:

  • To demonstrate controlled formation of two-dimensional (2D) objects from pure C60.
  • To investigate selective shape shifting of these 2D objects into one-dimensional (1D) nanostructures.
  • To elucidate the role of solvent-dependent crystal lattice changes in morphology transformation.

Main Methods:

  • Controlled crystallization of pure C60 at liquid-liquid interfaces using specific solvent mixtures (tert-butyl alcohol/toluene, i-propyl alcohol/CCl4).
  • Induction of shape transformation by exposing formed 2D nanosheets to water.
  • Analysis of crystalline structures and morphological changes using techniques not explicitly stated but implied by the results.

Main Results:

  • Uniform 2D hexagons and rhombi of pure C60 were successfully synthesized.
  • Exposure to water induced selective transformation of 2D nanorhombi into 1D nanorods.
  • Shape shifting correlated with changes in crystal lattice from mixed fcc/hexagonal to pure fcc, indicating a transition from metastable to stable structures.

Conclusions:

  • Pure C60 molecules can be controllably assembled into various 2D shapes (hexagons, rhombi) via simple solvent treatments.
  • Selective transformation of 2D C60 nanosheets into 1D nanorods is achievable through solvent-induced phase transitions.
  • This work establishes a method for precise morphological control of C60 assemblies, paving the way for tailored nanomaterials.
