Equipment of the working group
The chair has access to the common facilities of the CCB department, which ensures the basic supply of chemicals and gases and provides various analytical methods (NMR spectroscopy, elementary analysis, mass spectrometry, chromatography). We also use the LIDO3 cluster of the ITMC for quantum chemical studies with the programs ORCA, Gaussian and Turbomole. For the special experimental research typical work of our group the following infrastructure is available in our own laboratories.
Synthesis
For working under inert gas (argon/nitrogen) for preparation and for reaction studies of O2- or H2O-sensitive substances, our fume cupboards are equipped with modern Schlenck lines. Furthermore, several glove boxes are available (see below).
Glovebox system technology of the type MEGA E-Line
Inert gas complete systems with a total of 5 workstations, equipped with refrigerators / freezers
PureSolv MD 7 from Inert Systems
Drying system for the following solvents for synthesis and photophysical analysis of H2O-sensitive substances: Tetrahydrofuran, diethyl ether, toluene, dichloromethane, acetonitrile, n-pentane, cyclohexane
Other typical laboratory work techniques, such as spherical tube distillation, sublimation apparatus, high vacuum distillation and UV reactor are also available.

Magritek SPINSOLVE PHOSPHORUS 60 MHz ULTRA (1H, 19F and 31P) Benchtop NMR
The 3-nucleus NMR spectrometer is used for reaction control as well as kinetic investigation of catalytic conversions by means of a continuous flow cell and is also used for AC laboratory practicals.
(Rigaku)-Oxford Diffraction: Xcalibur with Sapphire CCD detector
For single crystal diffractometry for 3-dimensional structure elucidation and investigation of inter- and intramolecular interactions, there is access to the aforementioned diffractometer of the AC's teaching department.

Determination of melting point
Cyclovoltammetry and spectroelectrochemistry
Gamry 1010E Potentiostat / Galvanostat/ZRA
The potentiostate is used for precise impedance measurements and is operated with a (5 mL) voltammetric cell with a receptacle for three electrodes: GC (Glossy Carbon) electrode, platinum electrode and an Ag/Ag+ non-aqueous reference electrode. The tests can be performed for O2- and H2O-sensitive substances in an analytical glovebox.
In combination with our Agilent Cary 5000 (see below), spectroelectrochemical reflection experiments can be performed with the Gamry 1010E in a SEC-C spectroelectrochemical cell (platinum mesh as optically transparent working electrode and an Ag/Ag+ non-aqueous reference electrode).
UV/Vis absorption spectroscopy
Perkin-Elmer LAMBDA 265 UV/Vis spectrophotometer
For ultrafast measurement of absorption spectra for reaction control and extinction coefficient determination.
Agilent Cary 5000 double beam UV-vis-NIR spectrometer (175-3300 nm)
In addition to a sample chamber for solution samples, this high-performance absorption spectrometer is also equipped with a screwable inert sample chamber for solids (Praying Mantis) and thus allows investigations depending on the state of aggregation including polymer films even on sensitive compounds. The extremely high resolution of the spectrometer also allows the detection of formal spin-forbidden transitions and is helpful in spectroelectrochemistry in combination with the Gamry 1010E potentiostat (see above).

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".
