An object of the present invention is to provide a novel hetero ring-containing siloxane polymer, a composition and an electronic material composition containing the polymer, and an electronic element, which do not cause a decrease in luminous efficiency and driving stability of an electronic element, by adding the polymer to an electronic material composition or ink to be used for coating film formation. It has been found that the electronic element produced from the novel hetero ring-containing siloxane polymer, the composition and the electronic material composition containing the polymer exhibit improved luminous efficiency and driving stability, thereby completing the present invention.

Two novel star-shaped π-conjugated oligomers bearing a triphenylpyridine moiety as peripheral units and triphenylamine as a core have been synthesized via the threefold Heck/Sonogoshira coupling reaction protocol and their absorption and fluorescence properties have been examined. These oligomers showed excellent solubility in common organic solvents, emit light in blue and violet regions, and have
