Abstract
We report on the synthesis of three perylene-tagged electron donors representing three
major types – phthalates, diethers, and alkoxysilanes – which are of importance for
the subsequent studies of MgCl2-supported Ziegler–Natta catalysts by means of laser scanning confocal fluorescence
microscopy. The obtained products were unambiguously characterized, including by X-ray
crystal structure analysis; their photophysical properties (absorption and emission
spectra) were investigated as well. Additionally, a reliable and convenient protocol
for the multigram synthesis of the required starting material – 3-bromoperylene (PerBr)
– was developed. The key step of this method was synthesis of trialkylsilyl-substituted
perylenes, which were further separated by means of flash chromatography followed
by conversion of the isolated 3-trialkylsilyl-substituted product to PerBr.
