Phase-modulated ellipsometry of the J-aggregates of the title porphyrin shows that the material gives a true CD signal. This confirms that there is a real chiral transfer by mechanical forces, mediated by shear gradient flows, from the macroscopic to the electronic transition level. Dislocations in the structure of the aggregate could justify the formation of chirality at the level of the electronic transitions once the mesophases can be sculptured by hydrodynamic gradient flows.
对标题卟啉的J-聚集体进行相位调制椭圆偏振光谱分析表明，该材料给出了真实的圆二色性（CD）信号。这证实了存在由剪切梯度流介导的通过机械力从宏观到电子跃迁水平的真正手性转移。一旦中间相可以由流体动力学梯度流塑造，聚集体结构中的位错就可以解释电子跃迁水平上手性的形成。
