Molekulini

Molekulini is a term encountered mainly in speculative chemistry literature and in fictional or hypothetical discussions to denote a class of small, modular molecular building blocks. The name is derived from the word molekula (molecule) and a diminutive suffix, signaling their role as compact units designed to link together into larger structures. It is not universally recognized as an established chemical term.

In typical depictions, a molekulini has a relatively rigid core, often aromatic or heterocyclic, with two or more functional handles that enable selective coupling. Commonly proposed handles include halogens, alkynes, amines, or carboxylates. The design aims to allow predictable connectivity and tunable properties while maintaining stability under standard laboratory conditions.

Synthesis in these contexts is described conceptually as modular or bottom-up assembly, using established reactions such as cross-coupling, click chemistry, and stepwise solid-phase synthesis. Real-world realization depends on the chosen core and surface chemistry; researchers emphasize purity, yield, and the control of stereochemistry and conformation.

Potential applications include construction of supramolecular polymers, nanomaterials, sensors, and drug-delivery scaffolds, where the molekulini acts as a precise building block. Their modular nature is intended to facilitate rapid prototyping of materials with predefined geometry and functional groups.

In actual scientific practice, the term molekulini is not widely used or standardized. When discussing real chemistry, researchers more often refer to molecules, monomers, oligomers, or nanoscale building blocks, and prefer specific structural descriptors rather than a generic category. Related concepts include molecular building blocks, supramolecular chemistry, and nanoscale materials.
