A fluorescent D-A-D’ triad (1), composed of monocarbaborane, benzothiadiazole and triphenylamine, was synthesized. By replacing monocarbaborane with Ph, p-methoxyphenyl (PMP), or 4-pyridinyl (Py), 3 analogs were prepared for comparison. Monocarbaborane is an electron donating group based on the comparative anal. of NMR spectra and the systematic study of their photophys. properties. Triad 1 emits bright-yellow light in THF solution with the highest quantum yield and the longest decay time among these compounds It tends to form nanoparticles in aqueous THF solution The in situ generated nanoparticles might be used to detect Ag ions with high sensitivity and high selectivity. By holding the mols. via multiple CH···π interactions and electrostatic forces between the Et4N+ cation and the cage, a sheet-like arrangement of 1 is formed in the solid state with the smallest crystal d. that provides the maximum possibility of mechanofluorochromism from the crystalline to the ground form. By doping 1 in PVK, a white OLED is obtained. Crystallog. data are given. In the experimental materials used by the author, we found 4-Ethynylpyridine(cas: 2510-22-7Recommanded Product: 4-Ethynylpyridine)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Recommanded Product: 4-Ethynylpyridine
