Successful PhD of André Muthig
(27.10.2022)
We congratulate M. Sc. André Muthig on the successful defense of his PhD thesis (Near Infrared and Circular Polarized Luminescence of Donor Copper(I) Acceptor Complexes) and bid him farewell with best wishes.
Installation Edinburgh FS5
(14.10.2022)
In addition to the operation of the FLS1000, standard measurements for the investigation of the excitation and emission behavior can also be performed in the future with the FS5 Spectrofluorometer from Edinburgh Instruments. The use of a cryostat enables us to perform low temperature measurements at 77K in addition to measurements at room temperature.
Since the 2022 committee election, Prof. Dr. Andreas Steffen has been a member of the Senate Representation as of July 01, 2022.
First study on luminescent zinc complexes now available
(accepted 18.05.2022)
As of today, our first work on luminescent zinc compounds can be read in Chemistry - A European Journal. The novel Zn(II) complexes with cAAC ligands as chromophore exhibit extraordinarily long lifetimes, the cause of which was investigated and elucidated by comprehensive photophysical studies as well as supporting quantum chemical calculations by our cooperation partner Prof. Christel Marian (HHU Düsseldorf).
The SPP 2102 meets in Jena
(11.-13. Mai 2022)
Prof. Steffen and his co-workers M.Sc. Stefan Koop, M.Sc. Julia Kuhnt and M.Sc. Mousree Mitra participated in the meeting of Priority Program 2102 "Light-controlled reactivity of metal complexes" at the Friedrich Schiller University Jena and presented recent results in the field of zinc(II) emitters.
Approval of our SPP grant proposal
(Januar)
The second funding phase of the Priority Program 2102 "Light-controlled reactivity of metal complexes” has started and we’ll be part of the team, once again! Within the project "Design of circularly polarized NIR luminescence (CPL) by triad exchange of d10 complexes" we will investigate photoactive transition metal complexes once more in cooperation with our long-term collaboration partner Prof. Christel Marian (HHU Düsseldorf), this time focusing on the nickel triad.

Award of the Teaching Prize 2021, Category 1
(16.12.2021)
Prof. Steffen and Prof. Henke were awarded the TU Dortmund University's 2021 Teaching Prize, Category 1, for their extraordinary commitment and successful execution of the first-ever all-digital first-semester lecture "General and Inorganic Chemistry (AC1)" in the winter semester 2020/21.
Extension of Julia Kuhnt's PhD fellowship
(08.12.2021)
We congratulate M.Sc. Julia Kuhnt on the extension of her PhD scholarship at the Deutsche Bundesstiftung Umwelt (DBU) and wish her good luck on her way to the finishing line!
Transient absorption spectrometer up and running
(05.11.2021)
With the completion of the last renovation work in our laser spectroscopy room, our transient absorption spectrometer is now ready for use and opens up new possibilities for us to study photoactive systems in the excited state. By combining a streak camera (Hamamatsu) with a Nd:YAG laser connected to an optical parametric generator (Ekspla), we can excite samples between 210-2300 nm and subsequently study them over the entire near-UV and visible spectrum with a temporal resolution in the picosecond to millisecond range - and even at temperatures as low as 77 K.
We thank the German Research Foundation for their generous support and are already looking forward to exciting findings.
Patent application "Emitter material for OLEDs”
(November)
Based on M.Sc. André Muthig's promising work on chiral Cu(I) emitters, we have applied for the patent "Emitter material for OLEDs" (DE 10 2021 128 889.4) with our long-term cooperation partner Prof. Jens Pflaum (JMU Würzburg) and collaborators.
Dr. Andrei Beliaev receives Alexander von Humboldt Fellowship
(01.09.2021)
With the completion of his one-year postdoctoral fellowship from the Finnish Jenny and Antti Wihuri Foundation, Dr. Beliaev was able to secure two years of follow-up funding through a postdoctoral fellowship from the Alexander von Humboldt Foundation. Congratulations, we look forward to two more productive years with you!
Publication of our book chapter as part of CCC III
(19.07.2021)
The reference book Comprehensive Coordination Chemistry III has been published with our contribution "Design of Efficient Emissive Materials ". In addition to an introduction to the necessary photophysical theory and a discussion of general design criteria, we provide an overview of recent developments in the field of 3d transition metals, with a particular focus on Cu(I).

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dortmund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dortmund-Dorstfeld" (closer to Campus Nord). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from Campus Nord to Campus Süd by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus Nord and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station ("Dortmund Universität"). From there, suburban trains (S-Bahn) leave for Dortmund main station ("Dortmund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop "Dortmund Kampstraße". From there, take U43 or U44 to the stop "Dortmund Wittener Straße". Switch to bus line 447 and get off at "Dortmund Universität S".
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on Campus Nord. One ("Dortmund Universität S") is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".
