Design and synthesis of small molecules for NIR-operating light emitting and sensing devices

Organic chemistry of dyes and pigments offers a large number of synthetic tools for the production of innovative compounds to match the requirements of modern materials science. Near-infrared portion of the spectrum (700-2500 nm) is of particular interest, with application in bioimaging, photodynamic therapy, night vision, telecommunications and sensors. Among the thousands of different organic structure present in the literature, organic complexes of neutral tetrahedral boron (III), subphthalocyanine, squaraines and rare-earths complexes show attractive spectroscopic and chemical behavior such as as high absorption coefficients, red-shifted emission wavelengths, high quantum yields and high solubility in common organic solvents. In this work er report synthesis, characterization and application of such systems in OLEDs, photodetectors and LSC devices.
