Lecture: Self-assembled molecular nanoarchitectures on surfaces

The Department of Chemistry of Materials of the Faculty of Chemistry of the Czech Technical University invites you to a lecture within the Advanced Materials Seminar, which will take place in lecture room P8 of the Faculty of Chemistry on Monday, 13 February 2023 at 12:00.

In the lecture we will introduce the principle of molecular construction on solid surfaces by self-assembly. After a brief summary of general approaches to the formation of nanostructures (top-down, bottom-up, thermodynamics - growth kinetics approaches), we will introduce the main methods of analysis (STM and XPS) and non-covalent interactions leading to self-assembly. We will follow the principle of molecular self-assemblies on a selected system: biphenyl-dicarboxylic acids on Ag and Cu surfaces. We will introduce surface deprotonation, phase transformations, dipolar layer formation and surface polymerization.

The lecture will take place in the framework of the Advanced Materials Seminar, which is open to students and academic staff of the BUT as well as others interested in the presented topics.

Assoc. Ing. Jan Čechal, Ph.D.
Jan Čechal defended his PhD thesis in 2006 at the Department of Physical Engineering, Faculty of Physical Engineering, Brno University of Technology (supervisor Prof. Petr Dub). After completing his postdoctoral fellowship in the group of Prof. Klaus Kern (MPI for Solid State Research, Stuttgart), he returned to Brno University of Technology in 2012, where he participated in the preparation of the new CEITEC centre. In 2018, he was appointed as a junior research group leader, which in 2020, following an evaluation by the International Scientific Advisory Board (ISAB), was granted the status of a standard research group. The group now consists of 5 postdoctoral fellows, 5 PhD students and 6 MSc and BSc students. J. Čechal's research focuses on self-assembled molecular systems on material surfaces, with a view to quantitative description of their growth kinetics and external control of their properties by means of a graphene substrate.
