“…[29][30][31][32][33] In this work, we present the synthesis and characterization of a series of monocationic photoluminescent Ir III complexes (Ir1-Ir4, Figure 1), which incorporate conjugated ligands of different molecular length and are functionalized with suitable anchoring groups for their integration into metallic molecular junctions. [34,35] The new compounds result from the combination of iridium(III) bis-cyclometallated 2-phenylpyridine complexes with four different diimine π-conjugated ligands (1)(2)(3)(4). Ligands 1-4 are 1,10-phenanthroline (phen) derivatives symmetrically functionalized at their 3-and 8-positions with 1-(Sacetylthio)-4-phenyl and pyridine terminal groups, which are connected to the phen core by phenylethynyl spacers of different length.…”

“…[1][2][3][4] On this basis, the conductance of some single molecules contacted between metallic electrodes could be optically switched through light-triggered isomerization. [5][6][7][8][9] On the other hand, molecular-dipole changes have a deep influence on the electronic structures of contacted molecules.…”

“…[13][14] The introduction of pendant moieties, 15 or changes to the nature of the arylene fragment to modulate quantum interference pathways, 16 permits the assembly of wire-like molecules of a wide range of lengths [17][18] that are synthetically compatible with a diverse range of surface contacting groups. [19][20][21] The conductance of the OPE scaffold can also be modulated through the introduction of metal centers [22][23][24][25][26][27][28][29] or metallocene [30][31] fragments within this -conjugated pathway, which augments a fast growing area of study concerning metal coordination complexes as components in molecular electronics. [32][33][34][35][36][37][38][39][40][41][42] To date, the vast majority of metal compounds and complexes studied within metal|molecule|metal junctions or related sandwich structures formed by contacting monolayer films have been based on the Group 8, 9 and 10 metals, for reasons of synthetic availability and redox activity, in an axiallysubstituted arrangement within the wire-like assembly.…”

“…In order to address this issue, we designed and synthesized a new family of organometallic compounds, combining an ideal dithienylethene (DTE) photochromic unit3334 and a unique electro-active carbon-rich ruthenium complex3536373839, targeting multifunctional switching properties addressable with photon and/or electrons40414243. In a recent work44, we showed that the bimetallic compound 1 bearing two ruthenium fragments [AcS–C 6 H 4 –C≡C(dppe) 2 Ru] + (dppe=1,2-bis(diphenylphosphino)ethane) on either ends of a DTE unit exhibits the reversible photo-controllable switching of conductivity when placed within a pair of gold nanoelectrodes fabricated by on-wire lithography (OWL)454647.…”
