Expanded Radialenes: A Novel Class of Cross-Conjugated Macrocycles

Large cores composed exclusively of carbon, substituents only on the periphery, and nanometer‐scale dimensions—these are the characteristics of the title compounds 1 (n = 1; C40 + 8SiiPr3), 2 (n = 2; C50 + 10SiiPr3), and 3 (n = 3; C60 + 12SiiPr3). The π‐electron delocalization in these molecules is...

Zusammenfassung:Large cores composed exclusively of carbon, substituents only on the periphery, and nanometer‐scale dimensions—these are the characteristics of the title compounds 1 (n = 1; C40 + 8SiiPr3), 2 (n = 2; C50 + 10SiiPr3), and 3 (n = 3; C60 + 12SiiPr3). The π‐electron delocalization in these molecules is limited to the longest linearly conjugated fragment (TIPS = triisopropylsilyl).
