Synteesides

Synteesides is a term used in speculative chemistry to denote a hypothetical class of multifunctional organic molecules proposed as versatile crosslinking units in polymer synthesis. In thought experiments and science-fiction inspired analyses, synteesides are described as possessing a central core with three or more reactive termini, enabling rapid and controllable network formation during polymerization. The concept has not been established in peer-reviewed chemistry.

Structural features commonly attributed to synteesides include a modular core that can be rigid or flexible, and a set of orthogonally reactive groups such as amines, carboxylates, epoxides, or azides. These functionalities are envisioned to allow selective sequential reactions, precise placement of crosslinking points, and tuning of network topology. The design aim is to provide control over crosslink density, mechanical properties, and responsive behavior of the resulting polymer material.

Synthesis in the speculative literature often involves convergent assembly from a trifunctional or higher-order core, followed by protection and deprotection steps and sequential coupling. Routes frequently invoke click chemistry, amidation, or esterification under mild conditions to build the crosslinking framework while preserving selectivity among reactive groups.

Proposed applications include high-strength polymers, smart coatings, adhesives, and hydrogel networks with programmable swelling or self-healing capabilities. Advocates argue that synteesides could offer superior control over network architecture compared to conventional crosslinkers.

Status and reception: synteesides remain a hypothetical construct without validated experimental data. They appear mainly in theoretical discussions and fictional contexts, cited as a useful device for exploring ideas about polymer architecture and crosslinking strategies.
