The objective of this project is to prepare and investigate self-assembled microcrystalline upconverting materials based on Covalent Organic Frameworks. The upconversion process will be confined to the COF’s single crystal. For this purpose, three types of building blocks will be incorporated into the organic framework: the photosensitizer and the emitter, directly participating in the upconversion process, and the inert unit, providing spatial separation between photoactive units. Such targeted self-ordered crystalline material will be used to study the parameters governing the upconversion process, such as impact of the orientation and distances of respective units and their concentrations. Within the project, the structural tunability of COFs will be used for investigation of COF architecture related effects influencing the upconversion efficiency. Their comparative physicochemical studies (stationary absorption, steady state and time-dependent emission, and determination of upconversion yield) on targeted organic crystalline materials will provide information regarding factors hampering or enhancing the upconversion efficiency in the organic crystalline materials.

• Spectroscopic characterization of materials, collected data analysis and interpretation;
• Scientific initiative and contribution through regular reporting and publishing, as well as presenting at group meetings, national and international conferences;
• Providing help and supervision to junior members of the group;
• Contribution to the efficient functioning of the lab, including necessary administrative tasks.

The successful candidate is expected to start work within the project on the January 2024. It is possible to change the starting date in the justified case (but no later than 1 April 2024). 100% of the work time will be devoted to the realisation of the project. There are no teaching obligations. The post-doc would have access to supercomputer and specialized software in the Institute and on supercomputer of Poland (Polish Grid infrastructure).

The successful candidate will benefit in the form of new knowledge and methods added to his/her toolbox. The project deals with spectroscopy, nanophotonics, nanotechnology, physics, material sciences, and physical chemistry, so any candidate profile will find some new knowledge to be gained upon the realisation of the project.

We plan to publish the results of the work in high-impact factor journals.

The successful candidate will be able to take advantage of all programs in the IPC PAS, including Young Scientists of IPC PAS competition and Mobility of Young Scientists of IPC PAS competition. The Institute provides an opportunity to participate in ERASMUS+ program.

• PhD degree in chemistry, physics, chemical engineering, nanotechnology, or sciences, obtained no earlier than 7 years before the starting year of the employment in the project (this period might be longer due to family reasons (according to NCN rules).
• Good publication record and scientific experience.
• Ability to work independently as well as in a group.
• Significant research achievements in spectroscopy (Experience in the characterization of upconverting systems would be beneficial).
• Profound knowledge of photochemistry and photophysics
• Ability to communicate fluently in English (written and spoken).
• Strong motivation to work and pursue scientific questions, creativity, and analytical thinking.
• Research experience in related fields will be advantageous.

The Recruitment Commission will take into account the following criteria:

a) competencies of candidates for specific tasks in a research project (max 70 points),

b) previous scientific achievements of candidates (max 25 points),

c) awards and distinctions of the candidate resulting from the conducted research (5 points).

The commission evaluates applications on a point scale (max 100 points).
