We present an isomerism strategy to study the effect of molecular structures on radioluminescence. Under UV-light excitation, all isomers showed bright phosphorescence with an efficiency of up to 22.8 %. Unexpectedly, both m-BA and p-BA scintillators showed bright luminescence under X-ray irradiation, which was ascribed to both excellent electrical conductivity and efficient suppression of non-radiative decay.

异构现象对纯有机磷光闪烁体辐射发光的影响
我们提出了一种异构策略来研究分子结构对辐射发光的影响。在紫外光激发下，所有异构体都显示出明亮的磷光，效率高达 22.8%。出乎意料的是，m- BA 和p- BA 闪烁体在 X 射线照射下都显示出明亮的发光，这归因于优异的导电性和对非辐射衰减的有效抑制。
