Donor-acceptor phthalocyanine nanoaggregates.

摘要: A novel donor−acceptor bisphthalocyanine (bis-Pc, 1) in which two different Pc units (Zn(II)-Pc and Ni(II)-Pc) are linked via vinylene spacers to the pseudopara positions of a central [2.2]paracyclophane moiety is described. The synthesis 1 achieved by successive Heck reactions pseudopara-divinyl[2.2]paracyclophane 9 with, sequentially, zinc(II)- nickel(II)-iodophthalocyanine (4 5, respectively). self-assembly ability 1, result complementary character its phthalocyanine units, has been assessed variety techniques. It revealed that forms one-dimensional aggregates nanometer-sized dimension, whereas equimolar mixtures donor acceptor subunits 2 3, although strongly interacting, do not give large arrays. represent type supramolecular polymers based mainly upon interactions.
