Turbulene

Turbulene is a term encountered in theoretical discussions of chemistry to describe a hypothetical class of carbon-rich polycyclic aromatic hydrocarbons with highly twisted, nonplanar topologies. The name blends turbulence with the -ene suffix common to unsaturated hydrocarbons, but turbulene does not correspond to a single, established chemical structure in the peer‑reviewed literature. As a result, its use is largely pedagogical or speculative rather than descriptive of a concrete, experimentally characterized molecule.

Conceptually, turbulenes would consist of fused aromatic rings arranged in a way that prevents planarity, producing curvature or saddle‑like shapes. Such topology could disrupt conventional aromatic conjugation and lead to unusual patterns of aromaticity, potential chirality, and distinctive electronic properties. Theoretical models typically explore how different ring fusion schemes influence stability, electron distribution, and reactivity, often predicting nonstandard HOMO–LUMO gaps and altered optical or magnetic responses.

Synthesis and stability of turbulene variants pose major challenges. There are no widely accepted synthetic routes or isolable examples named turbulene in standard chemical databases. Highly strained, nonplanar PAH frameworks push the limits of synthetic feasibility and may require extreme conditions, stabilizing substituents, or novel assembly strategies to become viable targets.

In scholarly and educational contexts, turbulene serves to illustrate the impact of topology on molecular properties. If realizable, such species could have relevance for organic electronics, chiral materials, or nonlinear optical applications, though these prospects remain speculative pending experimental validation and consensus on definition. Related topics include polycyclic aromatic hydrocarbons, nonplanar aromatic systems, and concepts of topology in chemistry.
