ERC Starting Grant for Dr. Tim Schröder

Dr. Tim Schröder, junior research group leader at the Department of Physics of Humboldt-Universität zu Berlin and the Ferdinand-Braun-Institut, Leibniz-Institut fuer Höchstfrequenztechnik (FBH), was awarded an ERC Starting Grant and will receive EUR 1.5 million for five years.

With his project QUERP "Quantum Repeater Architectures Based on Quantum Memories and Photonic Encoding", Mr. Schröder is researching the next generation of faster, safer and future-compatible communication at the interface of integrated quantum optics, communication and new material systems.

He can also use resources from IRIS Adlershof when working on this topic. We congratulate and look forward to the continuation of our good cooperation.



Decision in the German Excellence Strategy

The Berlin University Alliance has won funding as a group in the Universities of Excellence funding line of the German federal and state governments’ Excellence Strategy. The German Council of Science and Humanities announced the decision on July 19, 2019, in Bonn. The four Berlin partners – Freie Universität Berlin, Humboldt-Universität zu Berlin, Technische Universität Berlin, and Charité – Universitätsmedizin Berlin – submitted a joint proposal entitled Crossing Boundaries toward an Integrated Research Environment and in a highly competitive process were able to convince the reviewers of its feasibility.




Article of IRIS junior research group leader Michael J. Bojdys published in Nature Communications

The IRIS junior research group leader Michael J. Bojdys and his international team have achieved a great success: Their article “Real-time optical and electronic sensing with a β-amino enone linked, triazine-containing 2D covalent organic framework” has been selected to be published in the renowned journal Nature Communications.
Bojdys article deals with aromatic two-dimensional covalent organic frameworks (2D COFs), which are a class of porous polymers that allow the precise incorporation of organic units into periodic structures.COFs can be chemically designed to incorporate particular surface functional groups which can be exploited to tune the optical and electronic properties. However, low stability towards chemical triggers has hampered their practical implementations.
Together with a team from the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (Prague, Czech Republic), IRIS junior research group leader Michael J. Bojdys and his team from Humboldt-Universität zu Berlin have explored a new design principle for COFs that makes use of strong, overall conjugation and incorporation of donor-acceptor domains. In this study a new, a highly stable chemoresistant β-amino enone linked, triazine-containing COF was used as a real-time, reversible optical and electronic sensor for volatile acids and bases. The team was further able to conclude that the sensing capabilities of the COF was achieved by preferential protonation
of the electron accepotor – a triazine ring in the structure – , resulting in an optical response visible to the naked eye and an increase of bulk electrical conductivity by two orders of magnitude. These findings demonstrate a powerful approach to design more practical sensors and switches, and take genuine advantage of the chemoresistant make-up, porous structure, and overall conjugation of fully-aromatic systems.
IRIS Adlershof would like to congratulate Michael J. Bojdys and his team on this successful study and its publication in Nature Communications!
Due to his great enthusiasm for the concept of IRIS Adlershof and the research carried out here, ERC-grant holder Bojdys joined the Humboldt-Universität zu Berlin and IRIS Adlershof in 2018 as leader of the junior research group “Functional Materials”. The group’s research aims at the development of metal-free, electronic components for transistors and sensors on the basis of functional materials made up of light, covalently-bonded atoms. At the heart of the project lies the challenge to transfer the control mechanisms and modularity known from molecular, organic chemistry to macroscopic structures.
