Studies on the oxidation of hydrazones with iodine and with phenylselenenyl bromide in the presence of strong organic bases; an improved procedure for the synthesis of vinyl iodides and phenyl-vinyl selenides
The oxidation of hydrazones by iodine in the presence of strong organic bases (guanidines) has been studied. Improved yields of vinyl iodides can be obtained by inverse addition using dry solvents and with a final heating period where appropriate. The reaction has been extended to various dihydrazones with interesting results.

A method for preparing a conjugated microporous polymer comprises the coupling of an alkynyl aryl monomer having a plurality of terminal alkyne groups with an iodo- or bromo-aryl monomer having a plurality of halogen atoms in the presence of a palladium (0) catalyst. The conjugated microporous polymer comprises nodes comprising at least one aryl unit and struts comprising at least one alkyne unit and at least one aryl unit, wherein a node is bonded from its aryl unit or units to at least two struts via alkyne units. Such polymers are useful in numerous areas such as separations, controlled release, gas storage and supports for catalysts.

The present invention is to provide a method of favorably forming an organic EL device with the inverted structure by the wet process. On that account, an organic EL device includes a cathode, an electron injection layer, a light emitting layer, a hole transport layer, a hole injection layer, an anode are formed in this order on a substrate. The electron injection layer is formed by applying ink between banks and drying the ink. The ink is formed by dissolving a polymer compound having an organic phosphine oxide skeleton in an alcohol solvent. The light emitting layer is formed by applying ink between components of the bank and the drying the ink. The ink is formed by dissolving material for light emitting layer such as polyphenylene vinylene (PPV) derivative or polyfluorene derivative in a nonpolar solvent.
