For the first time a pyrrolidinofullerene salt containing a spiropyran group and an ammonium group, capable of reversibly reacting to UV radiation, has been synthesized. Photoinduced reactions of the synthesized compounds were studied using absorption and luminescence spectroscopies, spectral and kinetic characteristics were measured. The hybrid molecule was found to exhibit intrinsic fluorescence even in the spirocyclic form. The C derivative showed a higher stability and better spectral and luminescent properties than the precursor.
首次合成了一种含有螺吡喃基团和铵基团的吡咯烷富勒烯盐，该盐能够对紫外光辐射进行可逆反应。使用吸收和发光光谱法研究了合成化合物的光致反应，测量了光谱和动力学特性。即使在螺环形式下，混合分子也表现出固有荧光。与前体相比，C 衍生物表现出更高的稳定性和更好的光谱和发光性能。
