TRIARYLAMINE HYDRAZONE DERIVATIVE AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR

PROBLEM TO BE SOLVED: To provide a compound that improves the electric characteristics of electrophotographic photoreceptors. SOLUTION: A triarylamine hydrazone compound is represented by formula (1) or a specific structure (R1 and R2 are halogen, an alkyl group, an alkoxy group, or an aryl group). SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT

TRIARYLAMINE DERIVATIVE AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER

A triarylamine derivative is represented by general formula (1) shown below. In general formula (1), R1, R2, and R3 each represent, independently of one another, a halogen atom, an optionally substituted alkyl group having a carbon number of at least 1 and no greater than 6, an optionally substituted alkoxy group having a carbon number of at least 1 and no greater than 6, or an optionally substituted aryl group having a carbon number of at least 6 and no greater than 12. In general formula (1), o, p, and q each represent, independently of one another, an integer of at least 0 and no greater than 4, and m and n each represent, independently of one another, an integer of at least 1 and no greater than 2.

Triphenylamine derivative, electrophotographic photosensitive member, and image forming apparatus

A triarylamine derivative is represented by general formula (I). In general formula (I), R1 and R2 each represent, independently of one another, a chemical group selected from the group consisting of a halogen atom, an optionally substituted alkyl group having a carbon number of 1-6, an optionally substituted alkoxy group having a carbon number of 1-6, and an optionally substituted aryl group having a carbon number of 6-12. In general formula (I), k and l each represent an integer of at least 0 and no greater than 4. When k and l represent integers greater than 1, chemical groups R1 bonded to the same aromatic ring and chemical groups R2 bonded to the same aromatic ring may be the same or different to one another. In general formula (I), m and n each represent a different integer of at least 1 and no greater than 3.

Triphenylamine derivative, electrophotographic photosensitive member, and image forming apparatus

A triphenylamine derivative is represented by general formula (1). In general formula (1), R1 to R7 each represent, independently of one another, a chemical group selected from the group consisting of a halogen atom, an optionally substituted alkyl group having a carbon number of at least 1 and no greater than 6, an optionally substituted alkoxy group having a carbon number of at least 1 and no greater than 6, and an optionally substituted aryl group having a carbon number of at least 6 and no greater than 12. Also, k, l, m, n, o, and p each represent, independently of one another, an integer of at least 0 and no greater than 4. When any of k, l, m, n, o, or p represents an integer greater than 1, chemical groups R3, R4, R5, R6, or R7 bonded to the same aromatic ring may be the same or different.

TRIPHENYLAMINE DERIVATIVE, METHOD FOR MANUFACTURING THE SAME, AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER

A triphenylamine derivative is represented by General Formula (1). In General Formula (1), OR1 represents an alkoxy group having 2 to 8 carbon atoms. R2 to R6 each independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms. Ar1 and Ar2 each independently represent a hydrogen atom, an aryl group having 6 to 20 carbon atoms and optionally substituted with an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 20 carbon atoms and optionally substituted with an alkoxy group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, or a 3- to 10-membered heterocyclic group. Note that the case where Ar1 and Ar2 are both a hydrogen atom is excluded.

Effect of substituents and conjugated chain length on the UV spectra of α,ω-di-substituted phenyl polyenes

A series of α,ω-di-substituted phenyl polyenes, p-X-Ph(CH = CH)nPh-p-Y (n = 1, 2, or 3) were synthesized, and their ultraviolet (UV) absorption maximum wavelength were determined. The correlation between molecular structure and the maximum wavelength energy (wavenumber/cm -1) was carried out. The results show that the maximum wavelength energy of the title compounds is mainly affected by both substituent excited-state parameters and maximum wavelength energy of the parent molecule. However, the two influence factors are not independent, and the action of substituent is governed by the parent molecular absorption energy. In the case of the compounds containing NO2 or NH2 groups, the influence of interaction of polarity parameters on the maximum wavelength energy must also be considered. In addition, the exploration was also made for the quantifying correlation of UV absorption maximum wavelength energy with the conjugated polarizability potential CPP replacing the parent molecular absorption energy. And the results indicate that the equation with CPP parameters is more accurate and convenient. Copyright 2013 John Wiley & Sons, Ltd.

Free Enthalpy Dependence of Free Radical Yield of Photoincuced Electron Transfer in Acetonitrile

The free enthalpy dependence of the free-radical yield ΦR of the electron-transfer (ET) fluorescence quenching was studied in acetonitrile by using anthracenecarbonitriles as the electron-accepting fluorescer and 1,4-diphenyl-1,3-butadienes as the electron-donating quencher. ΦR decreases, passes through a minimum, increases with increase of ΔGf, the free enthalpy change involved in the actual ET process, and then suddenly falls when ΔGf goes beyond -0.25 eV.Switchover of the quenching mechanism was suggested for the ET fluorescence quenching: The radical pairs are exclusively produced by the full ET in the encounter state bet ween the fluorescer and the quencher when ΔGf is smaller than -0.4 eV, but in contrast through the partial ET, i.e., the exciplex formation as the primary quenching products when ΔGf is larger than -0.4 eV.
