本文描述了一种利用手性纳米模板系统在非手性、全有机、低分子量荧光染料中通过手性诱导产生具有高度可调谐发射带的强圆极化发光的新策略。我们的方法允许第一个系统的调查，以澄清圆二色性和圆偏振发光强度之间的关系。结果，确定了迄今为止圆偏振发光强度最高且不对称系数超过0.1的稀溶液体系。
A new strategy is described for generating strong circularly polarized luminescence with highly tunable emission bands through chiral induction in nonchiral, totally organic, low-molecular-weight fluorescent dyes by chiral nanotemplate systems. Our approach allows the first systematic investigation to clarify the correlation between the circular dichroism and circularly polarized luminescence intensities. As a result, a dilute solution system with the highest circularly polarized luminescence intensity achieved to date and a dissymmetry factor of over 0.1 was identified.
