Kai and Olaia @ the German-Spanish Symposium on Functional Hybrid Nanomaterials

The German-Spanish Symposium on Functional Hybrid Nanomaterials took place on April 9 and 10, 2018 on the Occasion of the Inauguration of the Max Planck Partner Group on Coloidal Methods for Multifunctional Materials (CM3-Lab) at the University of Valencia. The symposium was organized by Dr. Rafael Munoz-Espi and Prof. Katharina Landfester.

New Paper “Asymmetric Covalent Triazine Framework for Enhanced Visible Light Photoredox Catalysis via Energy Transfer Cascade” in Angewandte Chemie

The construction of complex multiple component semiconductor photocatalyts allows enhanced catalytic efficiency via multiple charge and energy transfer, which mimics the nature photosystems. However, the efficiency of single component semiconductor photocatalysts is usually inhibited due to the fast recombination of the photo‐generated excitons. Here, we report the design of an asymmetric covalent triazine framework as efficient single component organic semiconductor photocatalyst. Four different molecular donor‐acceptor domains are obtained within the network, leading to an enhanced photogenerated charge separation via intramolecular energy transfer cascade. The superior photocatalytic efficiency of the asymmetric covalent triazine framework over its symmetric counterparts was demonstrated via the visible light‐driven formation of benzophosphole oxides from diphenylphosphine oxide and diphenylacetylene.

New Paper “CO2-Triggered Switchable Hydrophilicity of Heterogeneous Conjugated Polymer Photocatalyst for Enhanced Catalytic Activity in Water” in Angewandte Chemie

Water-compatibility of heterogeneous photocatalysts has been pursued for energy and environmental applications. However, there exists a trade-off between hydrophilicity and recyclability of the photocatalyst. MPIP researchers have designed a conjugated polymer photocatalyst with tertiary amine terminals that reversibly binds CO2 in water, generating a switchable hydrophilicity. The CO2-assisted hydrophilicity boosted up the photocatalytic efficiency in aqueous medium with minimum dosage. When CO2 was desorbed, the photocatalyst could be simply regenerated from reaction media, facilitating the repeated use of photocatalyst. The hydrophilicity/hydrophobicity control of the polymer photocatalyst has successfully showcased through a variety of organic photo-redox reactions under visible light irradiation in water.

Kai receives the guest professorship “la chaire TOTAL de la Fondation Ballard” at the University of Montpellier, France.

December 2015. The Fondation Ballard was established to enhance higher education and academic cooperation in Chemistry in southern France. The guest professorship “La chaire TOTAL de la Fondation Ballard” was created with financial support of TOTAL, to invite “internationally renowned scientists from outside France to perform research and teaching and to establish future exchanges and collaborations between the invited professor and host university.”

Kai is one of this year’s laureates to visit the Institute Charles Gerhardt at the University of Montpellier, France in December 2015. This institute is a flagship institution of the Centre National de la Recherche Scientifique (CNRS) particularly active in macro/supra-molecular chemistry, self-organization, hybrid materials and fundamental electrochemistry.

Prizes & Awards: Congratulations to Saman!

June 2015. Saman won the Poster Award at the European Polymer Federation Congress (EPF) on June 21-26, 2015. The title of his poster was “Heterophase photocatalyst from water-soluble conjugated polymers: a self-initiation example under visible light”.
