Pengerryksen

Pengerryksen is a fictional chemical compound used in theoretical discussions of materials science to illustrate properties of framework materials. It is described as a hybrid inorganic–organic solid with a porous, three-dimensional network that resembles metal-organic frameworks (MOFs). The name combines the surname Pengerry (a fictitious researcher) with the chemical suffix -ksen, signaling a crystalline framework class.

In proposed models, pengerryksen consists of metal nodes connected by organic linkers to form a lattice with one- to two-dimensional channels. The material is typically depicted as having a high surface area, tunable pore sizes, and chemical functionality that can be adjusted by changing the linker or metal choice. Reported hypothetical properties include chemical robustness to air and moisture, and adjustable electronic characteristics depending on composition.

Synthesis is described in thought experiments as a solvothermal or solid-state reaction between metal salts and designed organic ligands, conducted under inert conditions to promote crystallization. While treated as theoretical, typical characterizations include X-ray diffraction to determine structure, BET surface area measurements, and gas adsorption studies.

Potential applications in these hypothetical scenarios include gas storage and separation, catalysis, and sensing, where pore engineering and selectivity are central. Pengerryksen is commonly used in teaching to illustrate how framework materials can be tuned for specific guest molecules.

Etymology and history: the term Pengerryksen appears in speculative literature as a teaching example; as a fictional material, it does not correspond to a real compound in chemical databases. See also: metal-organic framework, porous materials, crystal engineering.
