01 / A WAY OF SEEING

Chemistry
in motion.

For Maciek Majdecki, a chemical reaction is more than a transformation of molecules. It is an opportunity to observe how matter, energy and light interact.

Known as Luminescent Chemist, he brings together rigorous organic synthesis and an unmistakable visual approach to chemistry. Fluorescence, changing colours and unexpected reaction patterns become ways of opening the laboratory to a wider audience.

His work moves between two scales: the molecular structures that determine a material's behaviour, and the extraordinary phenomena that emerge before our eyes.

03 / SCIENTIFIC RESEARCH

Beyond
the glow.

Behind the vivid experiments lies a research practice grounded in organic synthesis and the behaviour of functional molecular systems.

01 / SYNTHESIS

Building
molecules.

From asymmetric catalysis to the preparation of complex organic structures, his research examines how molecular architecture can be deliberately designed.

02 / PHOTOPHYSICS

Light & molecular
energy.

Research involving tetracene-based molecular systems and singlet fission explores how excited states and energy processes depend on molecular arrangement.

03 / MATERIALS

Organic
electronics.

His published collaborations extend to organic semiconductors and photon upconversion — connecting synthetic chemistry with functional materials.


04 / HIS PERSPECTIVE AT HELNIUM

ARTISTIC INTERPRETATION OF LUMINESCENCE

At Helnium, Maciek connects molecular science with the experience of witnessing a reaction. Where microscopy reveals structure, luminescence reveals matter's interaction with light and energy.
