A series of various furyl derivatives of pyrene were synthesized by Stille cross-coupling procedure. Their structures were characterized by nuclear magnetic resonance, and elemental analysis. Optical properties of the synthesized materials as well as their energy levels were investigated by ultraviolet–visible absorption supported by fluorescence spectra. All of the studied compounds exhibit fluorescence...
A novel multitriphenylamine substituted derivatives, possessing the respective photochromic groups were synthesized by Stille cross-coupling methodology. The hyperbranched structures have been characterized by 1 H NMR, 13 C NMR. Obtained structures show good stability in common organic solvents such as CHCl 3 , toluene and CH 2 Cl 2 and exhibit excellent thermal...
