Research

The basic research topics are in the interdisciplinary field of the structural organic analysis, carried out experimentally (by means of vibrational spectroscopy and X-ray diffraction) as well as theoretically (on the basis of modern non-empirical quantum-chemical methods). The research object is a large series of organic compounds (biologically active compounds, food additives etc., including isotope labelled ones), their hydrogen-bonded complexes as well as anions-intermediates in important chemical reactions. The results obtained make it possible to follow the spectral and structural variations, caused by the conversion of organic molecules into complexes and anions, as well as elucidation of the structure – activity relationship.

Тhe scientific expertise of the Group of Molecular Electronic Spectroscopy covers experimental investigations by UV-VIS absorption, steady-state and dynamic luminescent spectroscopy aiming at elucidation of the relationship between the structure (chemical and electronic) of conjugated organic compounds and the deactivation processes of their singlet and triplet electronically excited states.
The photophysical and photochemical properties of more than 800 organic compounds and dyes are studied, including pyrazolones, oxazolones, benzthiazoles, triazoles, benzopyranes, benzylidenephthalides, indanediones, indenones, coumarines and izo-coumarines, naphthiridines, perylene dyes, acridines, pyrylium and xanthilium dyes, porphyrins, merocyanine and asymmetric monomethincyanine dyes, etc.
Our research is directed to the possible application of the studied compounds as fluorescent markers for polymers, biopolymers and nanoparticles, and as bio- and chemical sensors.

The research of the Group of Vibrational spectroscopy is focused on infrared linear dichroism of molecules oriented in nematic liquid crystal matrices and infrared ellipsometric studies of thin films and self-assembled monolayers on metallic and silicon surfaces.

A recent research topic of the Laboratory “Structural Organic Analysis” is identification and study of Bulgarian historical and artistic objects by means of analytical techniques. The aim of the research is to support the preservation of the Bulgarian cultural heritage.
