Title:
NEW TRIPHENYLAMINE COMPOUND
Document Type and Number:
Japanese Patent JP2873548
Kind Code:
B2
Abstract:
PURPOSE: To obtain a new triphenylamine compound capable of keeping the amorphous state at normal temperature and forming a thin film as it is, having excellent heat resistance and useful as a photoelectric transducer element, etc., for various electronic devices.
CONSTITUTION: This triphenylamine compound is 4,4',4"-tris[N,N-(1-naphthyl) phenylamino]triphenylamine of formula I or 4,4',4"-tris[N,N-(2-naphthyl) phenylamino]triphenylamine of formula II. The compound of formula I can be produced by reacting 4,4',4"-triiodotriphenylamine with a 1- naphthylphenylamine compound and the compound of formula II can be produced by reacting 4,4',4"-triiodotriphenylamine with a 2-naphthylphenylamine compound. The above reactions are carried out in the presence of a base (preferably an alkali metal hydroxide) and copper powder in a solvent (preferably decalin). The compound of formula I has a melting point of 219°C, a molecular weight[M (m/e) by mass spectrometry] of 896 and a glass transition point of 113°C.
