dc.description.abstract
Sugar alcohols are interesting candidates for phase change materials (PCMs). Their strong hydrogen
bonding tendency gives them high thermal storage potentials. Recently, specific sugar alcohols with extended
chain length have been predicted by computational calculations to possess remarkably high values of latent
heat making them promising PCMs [1] (Scheme left). An even number of carbon atoms, no branching and all
hydroxy groups in 1,3-anti orientation have been identified as prerequisite. However, experimental validation
of these predictions is yet lacking as these materials are not readily available.
We aim to make these PCM candidates accessible for thermal evaluation. In order to obtain higher
sugar alcohols of C10 and longer chain length, we apply a dimerization approach [2]. Linking two sugar-derived
building blocks by metathesis allows us to directly and efficiently translate the natural stereochemistry of the
carbohydrates into our target materials.
We have already succeeded in the homo-coupling of a D-arabinose derived building block to the D-
manno-D-manno-decitol (manno-decitol, C10). Next, by combining differently sized precursors even higher
sugar alcohols (C12, C14) are accessible via (cross) metathesis. The synthesized compounds are being
investigated for their thermal properties and compared to their computationally estimated potentials.
