PRODUCTION OF SILICON-BASE HOLE TRANSPORT MATERIAL

Japanese Patent JP3614222

B2

PROBLEM TO BE SOLVED: To produce a hole transport material used for imparting charge- transport capability to a polysiloxane resin and soluble in this resin.
SOLUTION: Alkoxysilyl groups are introduced through hydrocarbon groups onto a part of or the whole of the aromatic groups of a hole transport compound which comprises a tertiary amine having a plurality of aromatic groups and has an ionization potential of 4.5-6.2eV to produce a silicon-base hole transport material. The unsaturated aliphatic groups bonded to the aromatic groups forming the hole transport compound are combined with an alkoxysilane having hydrogen atoms and alkoxy groups as the substituents for silicon atoms by hydrosilylation in the presence of a platinum compound catalyst, and the produced silicon-base hole transport material is brought into contact with an adsorbent for the platinum compound to remove the platinum compound together with the adsorbent to thereby reduce the platinum content to 10ppm or less.
