preparation example Construction
[0026] In the preparation of power transport compounds, A-(L-OH) n The material may be present in an amount from about 5% to about 30% by weight of the reaction mixture, such as from about 10% to about 25% by weight. R-OH may be present in an amount from about 50 wt% to about 95 wt%, such as from about 65 wt% to about 95 wt%, of the reaction mixture. The catalyst may be present in an amount from about 0.5% to about 10% by weight of the reaction mixture, such as from about 1% to about 6% by weight.
[0027] The overcoat coating composition may comprise from about 3 wt% to about 80 wt% electrical transport compound, such as from about 3 wt% to about 40 wt% or from about 5 wt% to about 40 wt% or such as from 3 wt% to about 30 wt% and from 3 wt% to about 20 wt% electrical transport compound .
[0028] The topcoat coating composition also includes a phenolic compound. A phenolic compound means, for example, any aromatic organic compound in which there is at least one benzene rin...
Embodiment 1
[0085] Embodiment 1: Preparation of N, N-bis(4-butoxymethylphenyl)-3,4-dimethylphenylamine:
[0086]
[0087] Compound (I)
[0088] N, N-bis(4-hydroxymethylphenyl)-3,4-dimethylphenylamine (25g), 1-BuOH (100g) and ion exchange resin AMBERLYST 15 (5g) mixture at room temperature Shake until the reaction is complete, as indicated by thin layer chromatography (TLC). The mixture was filtered to remove AMBERLYST 15 catalyst. Removal of the solvent under reduced pressure yields the electrotransporting compound (I) as an oily product. structure by 1 Confirmed by H NMR spectroscopy.
Embodiment 2
[0089] Embodiment 2: Preparation of N, N-bis(4-methoxymethylphenyl)-3,4-dimethylphenylamine:
[0090]
[0091] Compound (II)
[0092] A mixture of N,N-bis(4-hydroxymethylphenyl)-3,4-dimethylphenylamine (25 g), methanol (150 g) and ion exchange resin AMBERLYST 15 (5 g) was shaken at room temperature until The reaction was complete as indicated by TLC. The mixture was filtered to remove AMBERLYST 15 catalyst. Removal of the solvent under reduced pressure yields the electrotransporting compound (II) as an oily product. structure by 1 Confirmed by H NMR spectroscopy.
[0093] Photoreceptor Device: Comparative Example
[0094] The electrophotographic photoreceptor was prepared in the following manner. Preparations for the intermediate coating included 100 parts of a zirconium compound (trade name: Orgatics ZC540), 10 parts of a silane compound (trade name: A110, manufactured by Nippon Unicar Co., Ltd), 400 parts of isopropanol solution, and 200 parts of...
