What is the smallest tilt angle necessary for an [ n ]metallocenophane to undergo ring‐opening polymerization (ROP)? In previous work [ n ]metallocenophanes with tilt angles of up to 13° were found to be resistant to thermally induced ROP. The stanna[1]ferrocenophane 1 , the first [ n ]metallocenophane containing a heavy main group element in the bridge, has a tilt angle of only 14° but still polymerizes to yield novel high molecular weight poly(ferrocenylstannane)s 2 .
