文摘

In noncoordinating solvents, meso-cinchomeronimide appended Zn(II) porphyrin 2 forms a cyclictrimer, while diporphyrins 7 exhibit high-fidelity self-sorting assembling to form discrete cyclic trimer, tetramer,and pentamer with large association constants from 7_in-in, 7_in-out, and 7_out-out, respectively, through almostperfect discrimination of enantiomeric and conformational differences of the meso-cinchomeronimidesubstituents. In the latter self-sorting processes, the dihedral angles dictated by the two pyridyl nitrogenatoms control the size of the aggregates; the trimer from 7_in-in, the tetarmer from 7_in-out, and the pentamerfrom 7_out-out. Cyclic structures of (2)₃ and (R-7_out-out)₅ have been determined by single-crystal X-ray diffractionanalysis.
