Nitrogen K‐shell near‐edge X‐ray absorption fine structure (NEXAFS) measurements have been used for the first time to demonstrate 1D alignment of cobalt phthalocyanine (CoPc) molecules inside carbon nanotubes (see figure), revealing a stacking order consistent with the metastable α‐CoPc phase. In addition, transmission electron microscopy images show pristine nanotubes surfaces and near‐optimal filling. The smallest internal diameter to host CoPc molecules is found to be 15 Å.
