1.报告会简介

报告人:David Díaz Díaz教授

时间:2017年10月16日(星期一)上午10:00

地点:长安校区理学院383会议室

主题:Gel Networks As Reaction Media: Performing Air-Sensitive Photoredox Catalysis Under Aerobic Conditions

内容简介:

Nature uses confined and compartmentalized environments such as organelles to carry out chemical reactions under mild conditions with a precise control on kinetics and selectivity. Over the last few decades, this has served as an inspiration to develop artificial nanoreactors based on directed self-assembly of small molecules through non-covalent interactions.Within this context, photochemistry can benefit from confined spaces, for example when performed in mesoporous inorganic materials, microemulsions, micelles, vesicles, polyelectrolyte multilayered capsules, liquid foams, and gels. The confinement may improve photochemical processes by influencing key aspects, such as light absorption and the lifetime of redox intermediates. Additional advantages of confined media for photochemical reactions may include large reaction active areas, the possibility of tailoring additional functionalities to the microreactor environment, and the reduction of overheating and overconcentration effects. In this talk, our recent advances on the use of supramolecular gels as confined microenvironments for performing air-sensitive photochemical processes under aerobic conditions will be discussed, including the photoreduction of aryl halides via triplet-triplet annihilation-based photon upconversion (TTA-UC) as well as C–C cross-coupling reactions involving C–halogen and C–H bond photoactivation.

报告人简介

David Díaz Díaz received his PhD in Chemistry from the University of La Laguna under the supervision of Prof. Víctor Martín (Spain) (main topics: natural product synthesis and synthetic methodologies using transition metal complexes). In 2002, he joined Prof. Finn's group as postdoc at The Scripps Research Institute (CA, USA) (main topics: amidine chemistry, polymer synthesis and soft materials). Since 2006, he has held various positions in academia and industry ('Ramón y Cajal' Researchers, UAM, Spain, 2006; Sr. Chemist, Dow Chemical, Switzerland, 2007; Tenured Scientist, CSIC, Spain, 2009; Alexander von Humboldt Experienced Researcher, University of Regensburg, Germany, 2010). In 2013, he was awarded with the DFG Heisenberg Professorship and appointed as Associate Professor at the University of Regensburg. He has received the Young Investigator Award from the Polymer Network Group (Japan) and is the Editor-in-Chief of Gels. His main research interest focused on the development of functional soft materials.
