本文研究了非平面染料对卤化银的有效增感。过去曾认为许多非平面喹啉染料缺乏光谱增感,但从二个典型的咪唑杂环染料的试验来看,这种扭变的简单菁,对卤化银却是良好的增感剂。Brooker等人认为染料的空间平面性对溶液的光谱吸收有影响。对称染料由于空间拥挤,其吸收光谱移向长波,并呈现低消光。波长的变更与消光的改变呈一种线性关系。而对于高度不对称染料来讲,空间拥挤 This paper studies the effective sensitization of silver halide to nonplanar dyes. It has been thought in the past that many non-planar quinoline dyes lack spectral sensitization, but this twisted, simple cyanine is a good sensitizer to silver halide from two typical experiments of imidazole heterocyclic dyes. Brooker et al. Believe that the spatial planarity of the dye has an effect on the spectral absorption of the solution. Symmetrical dyes due to space congestion, the absorption spectrum shifted to long waves, and showed low extinction. Wavelength changes and extinction changes showed a linear relationship. For highly asymmetric dyes, space is crowded
