Problems solved by technology

However, there is a problem with this charge transport layer that the layer itself has poor mechanical strength and weak abrasion resistance since the low-molecular-weight compound is dispersed in the polymer.
The problem also arises that the lithium alkyls used, when bonded to bromine or ethylene oxide, are highly hazardous and toxic, so care must be taken in their handling

Embodiment 1

[0114] Synthesis of Charge Transport Polymers (17).

[0115] In a 50ml flask, put 1.0 g of N,N'-bis(1-naphthyl)-N,N'-bis[4-(2-methoxycarbonylethyl)phenyl]-[1,1'-bis phenyl]-4,4'-diamine, 2.0 g of ethylene glycol and 0.05 g of titanium tetrabutoxide, and the mixture was heated and stirred at 200° C. for 3 hours under a nitrogen stream. N,N'-bis(1-naphthyl)-N,N'-bis[4-(2-methoxycarbonylethyl)phenyl]-[1,1'-biphenyl]-4 was detected, After the 4'-diamine was consumed, the reaction system was heated at 200° C. while reducing the pressure in the reaction system to 0.5 mmHg (millimeter mercury column) to distill off ethylene glycol. In this way, the reaction was continued for 4 hours. Then, the reaction system was cooled to room temperature, and the product of the reaction was dissolved in 50 ml of toluene. The insoluble matter was filtered off with polytetrafluoroethylene (PTFE filter) having a mesh of 0.5 μm. The filtrate was added dropwise to 300ml of methanol with stirring. T...

Abstract

A charge-transporting polymer is represented by the following general formula (I-1) or (I-2): wherein A represents a group represented by the following general formula (II-1).

Description

technical field [0001] The present invention relates to novel charge transport polymers useful in various organic electronic devices such as electrophotographic photoconductors, photosensors and organic transistors. Background technique [0002] A charge transport polymer, a typical example of which is polyvinylpyrrolidone (PVK), is useful as a photoconductive material of an electrophotographic photoconductor, a photosensor, an organic transistor material, and the like. Such polymers can be formed into layers and the layers used as charge transport materials. As charge transport materials, charge transport polymers typically exemplified by PVK and low molecular weight compound dispersion systems in which charge transport low molecular weight compounds are dispersed in polymers are known. Low-molecular-weight compound dispersion systems are mainly used in electrophotographic photoconductors, especially, because in these systems, their raw materials can be varied and can easi...
