合成了一组具有不同N-芳基的空间屏蔽的四唑，并随后在光诱导的四唑-烯烃环加成反应中进行了评价。结果表明，随着相应腈亚胺分子HOMO能量的增加，环加成反应加快，环加成产物的荧光发射沿着红移.
A panel of sterically shielded tetrazoles with different N-aryl groups were synthesized and subsequently evaluated in the photoinduced tetrazole-alkene cycloaddition reaction. It was found that increase in the HOMO energy of the corresponding nitrile imines leads to a faster cycloaddition reaction along with a red shift in the fluorescence emission of the pyrazoline cycloadduct.
