Synthesis of chromophore end group containing poly(aryl ether) dendritic calixarenes using convergent approaches

In this study, by using convergent (from the surface to the nucleus) synthesis method, poly(aryl ether) dendritic structures and dendritic calix[4]arenes carrying 4-methyl?7-hydroxycoumarin (3) on the surface and 5,11,17,23-tetra-tert-butyl?25,26,27,28-tetrahydroxcalix[4]arene (9). At the focal point with zeroth (G-0) and first (G-1) generation number were synthesis by Williamson ether synthesis method.Synthesized dendritic structures, after being purified by chromatographic techniques, were proved by spectroscopic methods (FTIR, 1H NMR, 13C-NMR) and elemental analysis.The effect of the generation number on the absorption and emission properties of the synthesized dendritic structures was investigated. Because of the fact that chromophor group number of the structure increased molar absorptivity coefficients and emission intensities of the structure mentioned were determind to increase.
