Abstract:
A sextuple-decker heteroleptic phthalocyanine heterometallic compound (1) with a subunit arrangement of {(Pc)Sm(Pc)Cd(Pc*)Cd(Pc*)Cd(Pc)Sm(Pc)} has been prepared and analyzed using various spectroscopic instruments, in which four unsubstituted phthalocyanine anions (Pc) and two substituted analogues (Pc*) with n-pentoxyl substituents at eight peripheral positions are connected through the complexation of two Sm(III) and three Cd(II) ions. In particular, its sextuple-decker structure has been disclosed by the single-crystal X-ray diffraction technique. The solution and gel glass forms of this compound display third-order nonlinear optical properties due to the intrinsic conjugated nature over the sextuple-decker sandwich complex.

02:52Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
