Zinc-porphyrin-appended norbornene derivative 6, the corresponding dimer 7, coherently aligned single-stranded polynorbornene 5, and zinc-porphyrin-linked double-stranded polymeric ladderphane 3 have been used for complexation with 1,4-diazabicyclo[2.2.2]octane (DABCO) to generate an array of porphyrin-DABCO supramolecular scaffolds. The stoichiometries of the complex formation are analyzed in ...

In the crystal of the title compound, C(24)H(22)NO(2) (+)·CF(3)SO(3) (-), adjacent cations and anions are connected through C-H⋯O, C-H⋯F and S-O⋯π inter-actions, while neighboring cations via π-π inter-actions [centroid-centroid distance = 3.962 (2) Å]. The acridine and benzene ring systems are oriented at a dihedral angle of 14.6 (1)°. The carboxyl group is twisted at an angle of 87.6 (1)° rel...
