Molecular solar thermal
Molekulare solarthermische Systeme nutzen und speichern Sonnenenergie durch reversible Photoisomerisierung spezialisierter Moleküle.

Molecular Solar Thermal (MOST) systems store solar energy directly within the chemical bonds of photoswitchable molecules, most prominently the norbornadiene-quadricyclane couple, through reversible photoisomerization. Incident photons drive the molecule from a stable ground state to a strained high-energy valence isomer, which retains stored energy — potentially for months — until a catalytic trigger initiates the back-reaction, releasing heat on demand.

Die Systemleistung hängt von der Quantenausbeute, dem molaren Extinktionskoeffizienten (passend zum Sonnenspektrum), der Energiedichte pro Molekül, der Aktivierungsenergiebarriere der Rückisomerisierung und der Langzeitbeständigkeit über wiederholte Zyklen ab. Molekulare Funktionalisierung durch Substituentenmodifizierung und konjugierte Linker, Photoreaktoren mit kontinuierlichem Durchfluss und DFT-gestütztes Design definieren die aktuellen Forschungsschwerpunkte.
