Organic luminophores are widely used to create advanced devices in different areas of science and industry like nuclear physics, photonics, medical diagnostics and so on. Above applications are highly demanding to spectral characteristics of active molecules. In particular, luminescence spectra of organic luminophores should cover the wave length range from 300 to 700 nm. Additionally, absorption spectra must possess bands in a UV-Vis region (160-600 nm) with high extinction coefficient as 10+5 – 10+6 L*mol*cm-1 and much more. In ISPM RAS an approach to the synthesis of oligoarylsilanes consisting of several different luminescent fragments connected via silicon atoms has been developed1. This approach is very flexible and allows combining various functional fragments to obtain molecules with desired chemical structure and optical properties. The molecules synthesized possess unique properties: huge extinction coefficient, large Stocks shift and excellent luminescence quantum yield in a predefined spectral region, good solubility and processability that allowed to called them as nanostructured organosilicon luminophores (NOLs). In our innovative company LumInnoTech LLC we synthesize and upscale library of NOLs emitting in the whole spectral range. They can be used as effective spectral shifters in plastic scintillators and other radiation or elementary particles detectors, photodetectors, organic light emitting diodes and solar cells. Optical properties, solubility and phase behavior of NOLs can be flexibly tuned depending of the application requirements. We successfully developed a cost-efficient, low-waste technology of synthesis in pilot scale reactors. All luminophores synthesized are available for supply on demand in amount of hundreds grams.
