With the aim of designing new photoactive donor–acceptor dyads, self-assembly in the (ethoxy)(oxo)(5,10,15,20-(4-methylphenyl)porphinato)molybdenum(V) (O=Mo(OEt)TTP)–2′-(pyridin-4-yl)-5′-(pyridin-2-yl)-1′-(pyridin-2-yl-methyl)pyrrolidino[60]fullerene (Py₃F)-toluene systems was quantitatively studied using spectral methods (UV-vis, IR, ¹H NMR, mass spectrometry), chemical thermodynamics, and chemical kinetics. Interaction between O=Mo(OEt)TTP and pyridine (Py) proceeding as step equilibriums was preliminarily studied to model the processes above. The novel donor–acceptor triad based on O=Mo(OEt)TTP and Py₃F is represented with both quantitative description of its formation and conformation of the chemical structure. Prospects for the study of the triad as a photosynthetic antenna imitator and an active layer in organic solar cells are substantiated by a fluorescence method. Along with this, it has been demonstrated that O=Mo(OEt)TTP is a good candidate for use as an optical and fluorescent chemosensor of volatile organic compounds and nitrogen bases — the building blocks of pharmaceuticals, food components and environmental pollutants.

基于钼（V）四对甲苯基卟啉和取代富勒[60]吡咯烷的新型荧光猝灭三联体

为了设计新的光活性供体-受体二元体，在（乙氧基）（氧代）（5,10,15,20-（4-甲基苯基）卟啉）钼（V）（O = Mo（OEt） TTP)–2'-(吡啶-4-基)-5'-(吡啶-2-基)-1'^{使用光谱方法（UV-vis、IR、 1} H NMR、质谱）、化学热力学和化学动力学对-(pyridin-2-yl-methyl)pyrrolidino[60]富勒烯 (Py ₃ F)-甲苯体系进行了定量研究. 初步研究了 O=Mo(OEt)TTP 和吡啶 (Py) 之间的相互作用作为阶梯平衡进行，以模拟上述过程。基于 O=Mo(OEt)TTP 和 Py _{3的新型供体-受体三元组}F 用其形成的定量描述和化学结构的构象来表示。荧光法证实了将三元组作为光合天线模拟物和有机太阳能电池中的活性层的研究前景。除此之外，已经证明 O=Mo(OEt)TTP 是用作挥发性有机化合物和氮碱（药物、食品成分和环境污染物的组成部分）的光学和荧光化学传感器的良好候选者。
