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; C 40 + 8Si i Pr 3 ), 2 ( n = 2; C 50 + 10Si i Pr 3 ), and 3 ( n = 3; C 60 + 12Si i Pr 3 ). The π‐electron delocalization in these molecules is limited to the longest linearly conjugated fragment (TIPS = triisopropylsilyl).
