Exploring and tuning the anchorage of chlorophyllin molecules on anionic clays

Abstract

[EN] In experiments modeling photosynthesis, well dispersed chlorophyll molecules are required. A solution could be to anchor them on some host. In this work, new hybrid materials are synthesized using hydrotalcite and a chlorophyll derivative: chlorophyllin. Chlorophyllin is incorporated and dispersed in hydrotalcite through simultaneous precipitation or during hydrotalcite reconstruction. The effect of microwave irradiation on the crystallization step is discussed. In all cases stable materials are obtained, chlorophyllin molecules are isolated and bonded through hydrotalcite OH groups.
