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

Molekulare Solarthermie-Systeme (MOST) speichern Sonnenenergie direkt in den chemischen Bindungen von photoschaltbaren Molekülen, insbesondere des Norbornadien-Quadricyclan-Paares, durch reversible Photoisomerisierung. Einfallende Photonen regen das Molekül von einem stabilen Grundzustand in einen gespannten Zustand an. hochenergetisch Valenzisomer, das gespeicherte Energie – potenziell über Monate – beibehält, bis ein katalytischer Auslöser die Rückreaktion initiiert und dabei Wärme freisetzt.

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.

Abstract: Metallaphotoredox catalysis merges the powerful bond-forming abilities of transition metal catalysis with unique electron or energy transfer pathways accessible in photoexcited states, injecting new vitality into organic synthesis. However, most transition metal catalysts cannot be excited by visible light. Thus, prevalent metallaphotoredox catalytic systems require dual catalysts: a transition metal catalyst and a separate photosensitizer. This leads to inefficient electron transfer between the[...]

Abstract: Studying nanoscale self-assembly in real time using external stimuli unlocks new opportunities for dynamic and adaptive materials. While electrostatic self-assembly is well-established, real-time monitoring of its structural evolution under light irradiation remains largely unexploited.
