Rare-earth based tetrapyrrolic sandwiches: chemistry, materials and applications

“…5 Ferrocene-decorated double-and triple-decker mixed ligand complexes. 132 133,134 defined nano-rods and nano-sheets with conductivities of 3.85 Â 10 À5 and 2.48 Â 10 À5 S m À1 , respectively. This difference was attributed mainly to the more effective intermolecular p-electron delocalization in nano-sheets which was concluded from the analysis of X-ray diffraction patterns of the nanostructures.…”

“…This difference was attributed mainly to the more effective intermolecular p-electron delocalization in nano-sheets which was concluded from the analysis of X-ray diffraction patterns of the nanostructures. 134 2.3.2 Mixed ligand complexes with naphthalocyanines. Introduction of naphthalocyanines into mixed ligand complexes affords strong dissymmetrisation of electronic density due to anisotropic expansion of the p-system, which can be used for grafting of molecules in a well-defined fashion on various supports.…”

“…6) were synthesized and used as tectons for self-assembled nanostructures, formed upon injection of concentrated solutions of complexes in toluene into excess of methanol. 133,134 The morphology of the resulting aggregates was studied by various methods, and it was demonstrated that it governed their functional characteristics. For example, in the case of (A 1 -TPP)Eu(Pc) and (A 4 -TPP)Eu(Pc) this procedure resulted in the fabrication of uniform well-Scheme 23 Synthesis of sandwich mixed ligand complexes with spacered diporphyrin and X-ray structure of dilanthanum(III) complex (CCDC LUVWUX).…”

Self-assembled organic nanostructures and nonlinear optical properties of heteroleptic corrole–phthalocyanine europium triple-decker complexes

“…Nanostructures of the triple-decker compounds 1 and 2 were fabricated by the phase transfer method according to procedures reported in the literature [22,30,31] which are detailed below. A minimum volume (30e50 mL) of concentrated compounds 1 and 2…”
