List of topics for PhD thesis

Heteroaromatic compounds of boron for optoelectronic applications (Dr. Hrobarik)
The aim of the thesis is computer-aided design, synthesis, characterization and detailed photophysical study of heteroaromatic boron compounds based on the diborabezene or BODIPY skeleton for optoelectronic applications, including OLED materials, photodynamic cancer therapy and high-resolution bioimaging using laser fluorescence microscopy.

 

Highly efficient triplet photosensitizers for photodynamic therapy and phosphorescent bioimaging (Dr. Hrobarik) 
The aim of the thesis is computer-aided design and synthesis of novel thiazole-annulated heteroaromatic ligands with intramolecular charge-transfer and their complexes with various transition metal ions, as highly-efficient and photochemically stable triplet sensitizers for photodynamic therapy and phosphorescent bioimaging. The detailed photophysical and electrochemical characterization of the newly synthesized dyes and their application in biomedical applications will be performed in a close collaboration with our foreign partners.

 

Photocatalysts Operating in the Near-Infrared (NIR) Region (Dr. Hrobarik)
The aim of the thesis is rational design and development of new class of highly efficient photocatalysts absorbing light in the near-infrared (NIR) region by single- or two-photon absorption process. This also includes development of efficient synthetic strategies towards them and application of these catalysts in chemically and industrially relevant transformations.

 

Hybrid inorganic-organic photosensitizers displaying large multiphoton absorption (Dr. Hrobarik)
The aim of the thesis is computer-aided design, synthesis, characterization and detailed photophysical study of hybrid inorganic-organic systems with potential application in photodynamic cancer therapy and high-resolution bioimaging using laser fluorescence microscopy.

 

Metal-organic frameworks comprising multidentate ligands with intramolecular charge-transfer for nonlinear optical applications (Dr. Hrobarik)
The aim of the thesis is synthesis of novel metal-organic frameworks (MOFs) comprising of various transition metal/lanthanoid ions and multidentate charge-transfer ligands based on thiazole-annulated heteroaromatics. The synthesized nanoporous MOFs will be structurally characterized and investigated for their photochemical properties and potential application in various fields of materials chemistry, utilizing nonlinear optical phenomena.
