Bartholomew, Glenn P.; Bazan, Guillermo C. published the artcile< Synthesis, Characterization, and Spectroscopy of 4,7,12,15-[2.2]Paracyclophane Containing Donor and Acceptor Groups: Impact of Substitution Patterns on Through-Space Charge Transfer>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is hexylaminostyrylcyclophane preparation charge transfer structure.
The synthesis of 4,7,12,15-tetra(4′-dihexylaminostyryl)[2.2]paracyclophane (I), 4-(4′-dihexylaminostyryl)-7,12,15-tri(4”-nitrostyryl)[2.2]paracyclophane (II), 4,7-bis(4′-dihexylaminostyryl)-12,15-bis(4”-nitrostyryl)-[2.2]paracyclophane (III), 4,7,12-tris(4′-dihexylaminostyryl)-15-(4”-nitrostyryl)[2.2]paracyclophane (IV), 4,15-bis(4′-dihexylaminostyryl)-7,12-bis(4”-nitrostyryl)[2.2]paracyclophane (V), and 4,12-bis(4′-dihexylaminostyryl)-7,15-bis(4”-nitrostyryl)[2.2]paracyclophane (VI) is reported. These mols. represent different combinations of bringing together distyrylbenzene chromophores containing donor and acceptor groups across a [2.2]paracyclophane (pCp) bridge. X-ray diffraction studies show that the lattice arrangements of I and III are considerably different from those of the parent chromophores 1,4-bis(4′-dihexylaminostyryl)benzene and 1,4-di(4′-nitrostyryl)benzene. Differences are brought about by the constraint by the pCp bridge and by virtue of chirality in the paired species. The absorption and emission spectra of I-VI are also presented. Clear evidence of delocalization across the pCp structure is observed Further, in the case of II-IV, emission from the second excited state takes place.
