5,10,15,20-Tetrakis[4′-(terpyridinyl)phenyl]porphyrin and its Ruii complexes: Synthesis, photovoltaic properties, and self-assembled morphology

Abstract

A novel tetrakis(terpyridinyl)porphyrin derivative and its Ru(II) complexes were efficiently synthesized using microwave enhanced synthesis and shown to possess photovoltaic properties. Transmission electron microscopy and selected area electron diffraction were used to investigate its nanowire self-assembly.

Chemistry of Diruthenium and Dirhodium Analogues of Pentaborane(9): Synthesis and Characterization of Metal N,S‐Heterocyclic Carbene and B‐Agostic Complexes

“…These nanoscale dendritic architectures possess large molecular weights and broad absorption spectra (250–625 nm) as well as molar absorption coefficients directly related to the number of photoactive scaffolds. Notably, the reported utility of porphyrin‐based Ru II tpy complexes in dye‐sensitized solar cells31 provided the initial impetus to construct the perylene‐modified scaffolds for investigation as dyes for solar devices. Potential utility for the short lifetime <tpyRu II tpy> complexes lies in the unique and facile control over macromolecular architecture afforded by the terpyridine connectivity and the potential for modification.…”

“…More specifically, 2,2′:6′,2″‐terpyridine29,30 (tpy) ligands have gained increasing utility in metal–ligand coordination, particularly <tpyRu II tpy> complexes20,31,32 because of their potential utilitarian applications33,34 and interesting possible topologies, which include macrocycles35 and dendrimers 29,33,34. Metallodendritic architectures are monodisperse, well‐defined branched structures, and because light‐absorbing chromophores can be incorporated into their core and branches, the resultant materials can possess enhanced optical characteristics.…”

Porphyrins and phthalocyanines in solar photovoltaic cells

“…32 for an analogous situation using a phthalocyanine dye) [150]. Other metal-ligand combinations have been used to form networks of dyes for DSSCs [151]. Donor-acceptor clusters, such as fullerene-porphyrin clusters, have been aggregated onto gold nanoparticles via thiol groups and used as dyes for DSSCs (see Fig.…”

Coordination-Driven, Self-Assembly of a Polycyclic, Terpyridine-Based Nanobelt

“…In contrast to strictly linear porphyrin-terpyridine attachment [30], the bent spacer provides greater degrees-of-freedom; it can facilitate out-of-the-plane rotation (i.e., up or down) positioning of the terpyridine coordination sites [8b]. Herein, we present the high yield, coordination-driven, self-assembly of a belt-shaped, metallo-macrocycle with D 3 symmetry upon treatment of zinc tetrakis(terpyridinyl)porphyrin 3 with Zn 2?…”
