When a strong electron-withdrawing group (e.g., nitrobenzene group) is located on the position 3, the twisted configuration between pyrazoline ring and the substituted phenyl group on the position 3 is the fluorescence emission configuration of this kind of 2-pyrazolines, and the planar configuration between two moieties is also the best non-radiative decay configuration of these compounds.

对于C3位取代基为强的拉电子基团的化合物，C3位取代基与吡唑啉环相扭曲的构象是化合物分子的发光构象，而两者处于同一平面的构象是化合物的最佳非辐射衰变构象，与N1所联取代基的旋转扭曲无关。

It can be proposed that when the substituent is an electron donor, the twisted configuration between pyrazoline ring and the moiety attached on N1 is the fluorescence-emitted configuration of 2-pyrazoline, and the configuration where two moieties are placed in a co-plane is the best non-radiative decay configuration of these compounds.

这表明，对于C3位取代基为推电子基或弱的拉电子基团的化合物，N1所联取代基与吡唑啉环相扭曲的构象是化合物的发光构象，两者处于同一平面的构象是化合物的最佳非辐射衰变构象，与C3所联取代基的旋转扭曲无关。
