The synthesis, structure, and size-dependent properties of ferrocene-embedded conjugated macrocycles are described. The one-pot, two-component "shotgun" synthesis greatly expands the structural diversity and functionality of nanohoops. These η5-type coordination metal-nanohoops exhibit intriguing properties, including reversible redox behavior and collisional quenching with fullerenes. Notably, the addition of oxidants enhances their fluorescence intensity, while fullerenes quench it. Detailed theoretical and experimental studies reveal that fine-tuning the nanohoop size significantly influences not only the molecular conformation but also its electronic structure and photophysical properties.

基于二茂铁的共轭大环化合物：鸟枪法合成、尺寸依赖性特性和可调荧光强度


描述了二茂铁嵌入的共轭大环化合物的合成、结构和尺寸依赖性特性。一锅、两组分“鸟枪”合成极大地扩展了纳米环的结构多样性和功能。这些 η5 型配位金属纳米环表现出有趣的特性，包括可逆氧化还原行为和与富勒烯的碰撞猝灭。值得注意的是，氧化剂的添加增强了它们的荧光强度，而富勒烯则淬灭了荧光强度。详细的理论和实验研究表明，微调纳米环尺寸不仅会显着影响分子构象，还会显着影响其电子结构和光物理性质。
