文章合成了N,N’-二正丁基四羧酸二酰亚胺,并纯化、调晶,进行了IR、元素分析、X射线等测定。分析该化合物在DMF中的紫外光谱(最大吸收波长524.80 nm)、荧光光谱(最大发射波长539.0 nm)、Stokes位移(数值15 nm)等光谱性质。在400~700 nm范围内,α晶型薄膜紫外-可见吸收出现很强的吸收峰,且由β型变为α型,最大吸收波长有明显的红移(545 nm变为580 nm)。X射线粉末衍射也反映出α晶型的2θ在26.0°处衍射峰CPS为2 508,β型在25.2°为1 891。α,β晶型作为电荷产生材料制得的功能分离型有机光导体,在光源滤波波长λ=532 nm曝光下,测得含α,β感光体达到饱和电位的时间分别为46,93.98 s,光衰电位(5.3千伏电压负充电电晕,1~2 s后的表面电位)分别为727和525 V,半衰曝光量分别为4.32,4.34μJ.cm-2,残余电位分别为30和45 V等光导性能数值。
In this paper, N, N’-di-n-butyl tetracarboxylic diimide was synthesized, purified, crystallized and characterized by IR, elemental analysis and X-ray diffraction. The compounds were characterized by UV spectroscopy (absorption maximum 524.80 nm), fluorescence spectra (maximum emission 539.0 nm) and Stokes shift (15 nm) in DMF. In the range of 400-700 nm, there is a strong absorption peak in the UV-visible absorption spectrum of the α-crystalline film. From β-type to α-type, the maximum absorption wavelength has obvious red shift (545 nm to 580 nm). X-ray powder diffraction also shows that the 2θ of the α crystal forms a diffraction peak CPS of 2 508 at 26.0 ° and a β-type at 25.2 ° of 1 891. α, β crystal as a charge-generating material, the time when the photoreceptors with α and β are saturated reaches 46,93.98 s, respectively, under the light source filter wavelength λ = 532 nm. The decay potentials (5.3 kV volts negatively charged corona, surface potentials after 1 ~ 2 s) were 727 and 525 V respectively, the half-decay exposures were 4.32 and 4.34 μJ · cm-2 respectively, and the residual potentials were 30 and 45 V and other optical performance values.
