Understanding the Mechanism of Covalent Organic Framework Synthesis
Covalent organic framework (COF) materials have drawn intense attention in recent years due to their covalent bond supported crystallinity resulting in precisely controlled atom and pore distribution. The diversity of COFs has been greatly expanded by synthetic efforts, exploring various building blocks and designing new topological structures. However, most of the COF materials are obtained in a powdered state as a result of the widely used solvothermal synthesis method. From the powdered state two major problems arise, limiting further development: i) the presence of abundant boundaries causing a bias when determining intrinsic physiochemical properties; ii) the unevenness and discontinuity interfere with charge/mass transfer and diffusion processes thus constraining related applications. Thus, there is a need to teach the community to produce this class of materials into neat and smooth films. You will learn to use physical-organic considerations, such as advanced chemical kinetics, to develop high quality COF films. You take projects within COFs from the discussion stage, over all steps in the project cycle to finished manuscripts. You will also be encouraged to implement your previous research knowledge into projects. This in order to break new ground within the broad research topic of COFs, and also to promote your abilities to conceptually develop projects, which is of importance in a future career as an independent research leader. See the following group articles for an introduction to the research topic:

- To be eligible for a postdoctoral scholarship at the Department of Chemistry and Molecular Biology, the recipient must hold a PhD degree within a relevant field. The applicant must not have been employed at University of Gothenburg in the past two years.
- Please specify your experience, knowledge and/or interests necessary for this project. A suitable background for the applicant is a PhD within materials chemistry. Thus, a broad knowledge within the hands-on synthesis and/or characterization of organic materials is expected from the applicant. Further is it expected that the applicant will have taken responsibility of research projects before. This will be evaluated based on the quality of first author publications.
Written application, including reference number, is to be sent via e-mail to the supervisor and must include the following:
- Personal letter stating the reasons why the study suits the applicant (maximum one page)
- List of publications
- References (2)
Application deadline: 2022-08-31
