Enviroment | Coordination Chemistry Lab.

Major part of our laboratory is located on the 10th floor of West Zone building 1-B.
The lab consists of 8 rooms; Professor Room, Seminar Room, Assoc. Prof. Room, Experimental Room 1, Experimental Room 3, Experimental Room 4, Measurement Room 1, and Measurement Room 2.

This room is Professor Room where Prof. Sakai usually does desk work. The desk of Ms. Uchida, technical staff of our lab, is also located in this room and she supports Prof. Sakai every day.
In this room, there are some units which Prof. Sakai designed and constructed himself for efficient utilization of space, a moving screen system and a wood frame for whiteboard etc.
These units allow us to smoothly discuss research and write papers.

This room is Seminar Room. We use this room as one of the student room for research works except synthesis and measurement.
Two Assistant Professor, Dr. Yamauchi and Dr. Ozawa, also work in this room. In our lab, almost all computer were connected in one firewall so that we can exchange data and print documents comfortably.
This system allows us to conduct DFT calculations as we sit in our desk.

This room is Experimental Room 1. The area of this room is almost 100 m². Experimental Room 1 is largest room in our laboratory and equipped to synthesize metal complexes and its ligands.

There are seven fume hoods and two of them have scrubber for protection against deterioration of machines by acid. In these fume hoods, oil baths and Dimrohth condensers are placed for reflux of harmful organic solvents.
Additionally, there are many rotary evaporators in this room and we can remove solvents without waiting in line. We can also purify the compounds with column chromatography or HPLC in this room.

This room is Measurement Room 1. We can investigate the reaction relevant to metal complexes with many methods. In particular, Automated H₂/O₂-Analyzing System is important for our recent main theme, photo-driven water splitting. This system can measure a volume of H₂ and O₂ automatically at regular intervals.
Additionally, a semi-micro balance and micro balance are placed in this room. We can weigh the compounds to five or six decimal places with these balances. In investigation of the reaction, it is very important to finely determine the concentration of solutes.
Furthermore, the compounds synthesized in our lab is usually precious and must be used in small amounts as much as possible. Therefore, these balances, which can allow us to weigh precisely a small amounts of compounds, are keystone for all measurements in our lab.
On the other hand, UV-Vis spectrometer, UV-Vis-NIR spectrometer, spectrofluorophotometer, xenon lamp, apparatus for electrochemical measurements, IR spectrometer, nanoparticle analyzer, and dissolved oxygen meter etc. are placed in this room for the analysis of the chemical reaction from several view points.

This room is one of the student room, Experimental Room 3.

We can enjoy a view of mountains of Ito and Hakata Bay from this room.

Measurement Room 2 is located front of Experimental Room 3. This room is equipped with two apparatuses for electrochemical measurements, gas chromatography, xenon lamp, UV-Vis spectrometer, two electric furnaces, screen printer for preparation of TiO₂ electrode, desk balance, and microscope etc.
Two electric furnaces and screen printer are used for the development of solar conversion devices relevant to the research of Dr. Ozawa, “Development of solar-light energy conversion system based on metal complexes”.
Additionally, one apparatus for electrochemical measurement is equipped with EQCM (Electrochemical Quartz Crystal Microbalance). EQCM allows us to observe quantitatively minute change of weight of electrode in the process of the redox reactions of metal complexes in interfacial surface between liquid phase and electrode. We can electrochemically analyze the detailed reaction mechanism with this apparatus as well as photochemical methods.

Experimental Room 4 is one of the student room same as Experimental Room 3. However, this room has larger space than Experimental Room 3.

Additionally, the most characteristic point is that there is window in the side of this room, which encourage us to study actively in open-minded environment. There are many storage space in this room and tools for softball and BBQ are placed.

Assoc. Prof. Room has been used since 2017. Assoc. Prof. Ozawa, postdoctoral researchers, and some doctoral students work their own studies in this room.
