karboksylipaon

Karboksylipaon is a term used in speculative chemistry to describe a hypothetical class of carbon-rich, carboxyl-functionalized species. In thought experiments, karboksylipaon denotes a central framework bearing multiple carboxyl groups (−COOH) or their deprotonated forms (−COO−), arranged to confer high acidity and tunable solubility. The name combines the root for carboxyl with a suffix used in fictional nomenclatures to denote polyfunctional anions. This construct serves as a conceptual tool for exploring how dense carboxyl functionality might influence molecular stability, acidity, and interactions with solvents or metals.

Structure and properties are envisioned as highly variable, depending on the chosen core scaffold. Predicted geometries range from planar aromatic assemblies to cage- or cluster-like architectures. The presence of multiple electron-withdrawing carboxyl groups is expected to stabilize negative charge upon deprotonation, potentially yielding stable polyanionic species in aqueous or coordinating environments. In their deprotonated state, karboksylipaons are often imagined to form salts with alkali or alkaline-earth metals and to exhibit strong hydration or specific metal binding characteristics.

Synthesis of karboksylipaon remains purely theoretical. In published thought experiments and computational studies, hypothetical routes include direct carboxylation of a predesigned carbon framework or sequential functionalization of a polyfunctional core to introduce multiple carboxyl groups. Practical stability, solubility, and reactivity are shown to be highly sensitive to the core structure and pattern of substitution.

Applications are speculative and primarily discussed in the context of theoretical materials science or advanced modeling. Potential roles include acting as high-capacity ligands, platforms for studying carboxyl-rich interfaces, or conceptual models for CO2 capture and storage. No experimental realization has been reported, and karboksylipaon remains a theoretical construct.
