Highly fluorescent dendrimers containing stilbene, and 4-styrylstilbene with resorcinarene cores:: Synthesis and optical properties

Dendron conjugated branches of stilbene and 4-styrylstilbene groups have been attached to resorcinarene cores. A noticeable effect in solution for all dendrimers was observed in the fluorescence quantum yield. The optical properties do not change with concentration in solution. The optical properties of thin films are identical to those of the solutions indicating the absence of intermolecular interactions. The dendrimers were characterized by I H, C-13 NMR, FTIR, UV-Vis, fluorescence spectroscopy, MALDI-TOF or FAB+ mass spectrometry, and elemental analysis.
