| Abstract: | We report the synthesis and stereochemical properties of a new class of molecules containing a covalently-linked porphyrin and spiro-9,9′-bifluorene derivatives. The large spiro substituents hinder rotation about the meso position to give atropisomers which can be detected by 1H NMR after phosphine or isocyanide complexation to the ruthenium spiroporphyrins. |
