Novel neutral oxocarbons were computationally studied. The most stable structures, C(9)O(9) and C(12)O(12), exhibit benzene-like rings and enhanced stability due to aromaticity, aligning with experimental data.

Area of Science:

  • Computational chemistry
  • Materials science
  • Organic chemistry

Background:

  • Polycyclic neutral oxocarbons are an emerging class of carbon-oxygen compounds.
  • Understanding their stability and structure is crucial for potential applications.

Purpose of the Study:

  • To computationally investigate the structures and stability of novel oligomeric polycyclic neutral oxocarbons.
  • To identify the most stable oxocarbon structures for further experimental research.

Main Methods:

  • Density functional theory (DFT) calculations using the B3LYP functional.
  • Analysis of calculated dissociation enthalpies to determine structural stability.
  • Geometric optimization and electronic structure analysis.

Main Results:

  • A series of novel oligomeric polycyclic neutral oxocarbons were computed.
  • The most stable structures identified are C(9)O(9) and C(12)O(12), featuring a central benzene-like ring.
  • Enhanced stability of these structures is attributed to their aromaticity, consistent with experimental findings.

Conclusions:

  • The study successfully predicted stable structures for novel oxocarbons.
  • Aromaticity plays a key role in the enhanced stability of these compounds.
  • Identified stable oxocarbons serve as promising candidates for future experimental synthesis and investigation.
