-
Page/Page column 8, (2008/06/13)
The present invention provides a process for producing a hydrazone compound represented by the general formula (5): which comprises a step of condensing a hydrazine compound represented by the general formula (3): with a carbonyl compound represented by the general formula (4): without taking the hydrazine compound out of a reactor. According to the invention, the target hydrazone compound can be obtained in high quality and in a high yield without taking the hydrazine compound out of the reactor at all, the hydrazine compound being a reaction intermediate which is structurally unstable and has a fear of influencing safety of workers owing to its toxicity (mutagenicity).

For the purpose of elucidating charge transport in disordered organic materials, hole transport in the glassy state of 4-diphenylaminobenzaldehyde diphenylhydrazone (DPH), 4-diphenylaminobenzaldehyde methylphenylhydrazone (DPMH), and DPH doped with a small amount of 4-diethylaminobenzaldehyde diphenylhydrazone (DEH) has been studied.The hole drift mobility in the DPMH glass was approximately one-fifth of that in the DPH glass; this was attributed to a higher activation energy in terms of the Arrhenius formalism or to an increased width of the Gaussian density of states based on the site energy disorder model for the DPMH glass.The introduction of less than 1 molpercent DEH into DPH resulted in a significant increase in activation energy or in the Gaussian width of the site energy distribution, which increased with increasing concentration of the dopant. - Keywords: 4-diphenylaminobenzaldehyde diphenylhydrazone, 4-diphenylaminobenzaldehyde methylphenylhydrazone, 4-diethylaminobenzaldehyde diphenylhydrazone, mobility, charge transport, Poole Frenkel, photoconductivity, trapping
