The ellipsoid-of-revolution hydrodynamic model of molecular reorientation was used to interpret the results of fluorescence anisotropy decay measurements for 9-acetoxy-10-phenylanthracene, 9-acetoxy-10-biphenylanthracene, 9-acetoxy-10-(4′-acetoxyph

The absorption spectra of the bichromophoric 9-acetoxyanthracene compounds contain three electronic transitions in the visible and UV region. The spectra have similar shapes as the spectrum of the free chromophor 9-acetoxy-10-(2′,4′-acetoxyphenyl

The absorption and flourescence spectra, flourescence quantum yields and decay times were measured for the first time for six 9- acetoxy-10-halogenophenylanthracene derivatives. It is found that the rate constant of radiative (κ F ) and non-radiativ

Four new methoxy-substituted derivatives of E,E-2,5-bis(2-phenylethenyl)pyrazine have been synthesized. The supramolecular structures of the resulting set of five polymorphs have been studied using single-crystal X-ray diffraction to gauge the influe

Series of diaryl ethers, amines and amides have been synthesized and tested for antitumor activity. These diaryl compounds possess some of the structural features of combretastatin A-4 (a potent antimitotic agent). They were designed to discover whet
