This paper aims to investigate the electrochromic properties of tricarbonyl rhenium complexes. Using 4,7-diphenylphenanthroline (L1) and 4,7-di(4-substituted)-1,10-phenanthroline (L2-L5) as bidentate ligands, tricarbonyl rhenium complexes, fac-Re(CO)3(Lx)Cl (x = 1-5), were synthesized and characterized by IR spectroscopy, 1H NMR, 13C NMR, and high resolution mass spectrometry. Their stereochem. was investigated by single crystal x-ray diffraction. Theor. HOMO and LUMO charge distributions of fac-Re(CO)3(Lx)Cl were calculated by d. functional theory calculations Their electrochem. and electrochromic properties were studied by cyclic voltammetry, UV-visible spectroscopy and chronoamperometry. All fac-Re(CO)3(Lx)Cl complexes underwent a quasi-reversible reduction-oxidation process and an anodic peak at 1.3 V vs. Ag/Ag+. Electrochromic devices based on fac-Re(CO)3(Lx)Cl exhibited good electrochromic performance such as an obvious change in color from bleached yellow state to colored green state (a challenging electrochromic color), rapid response time of <3 s, moderate optical contrast and coloration efficiency, and good switching stability (fac-Re(CO)3(L2)Cl retained 95.2% of its initial optical contrast after 2400 electrochromic switching cycles). The fac-Re(CO)3(L2)Cl with an electron-donating group (-OCH3) at its para-position exhibited better performance including good switching stability, a higher optical contrast and a significant change in color than the unsubstituted, -CH3 substituted, -COOCH3 substituted and Br-substituted analogs. In the experiment, the researchers used 4,7-Bis(4-bromophenyl)-1,10-phenanthroline(cas: 97802-08-9Safety of 4,7-Bis(4-bromophenyl)-1,10-phenanthroline)

A series of phenanthroline-based ligands have been synthesized and their influence as bidentate nitrogen ligands in heteroleptic [Cu(PP̂)(NN̂)]+ photosensitizers in light-driven water reduction has been studied. In this noble-metal-free Cu-Fe-based photocatalytic water reduction system, the structural effects of the nitrogen ligands have been explored, including the steric and electronic effects of substituents at the 2,9- and 4,7-positions of phenanthroline. Ligands were prepared that led to increased hydrogen generation, with turnover numbers (TONCu) of up to 1388 being observed All the new complexes were electrochem. and photophys. characterized. We demonstrate for the first time that the presence of fluorine in nitrogen ligands increases the efficacy of copper complexes in photocatalytic hydrogen production The experimental part of the paper was very detailed, including the reaction process of 4,7-Bis(4-bromophenyl)-1,10-phenanthroline(cas: 97802-08-9SDS of cas: 97802-08-9)

Yuan, Zheliang; Wang, Hao-Yang; Mu, Xin; Chen, Pinhong; Guo, Yin-Long; Liu, Guosheng published an article on February 25 ,2015. The article was titled 《Highly Selective Pd-Catalyzed Intermolecular Fluorosulfonylation of Styrenes》, and you may find the article in Journal of the American Chemical Society.Reference of 4,7-Bis(4-bromophenyl)-1,10-phenanthroline The information in the text is summarized as follows:

A novel Pd-catalyzed intermol. regio- and diastereoselective fluorosulfonylation of styrenes has been developed under mild conditions. This reaction exhibits a wide range of functional-group tolerance in styrenes and arylsulfinic acids to afford various β-fluoro sulfones. Preliminary mechanistic study reveals an unusual mechanism, in which a high-valent L2PdIIIF species side-selectively reacts with a benzylic carbon radical to deliver a C-F bond. This pathway is distinct from a previously reported radical fluorination reaction. Thus, e.g., treatment of E/Z-β-methylstyrene with NFSI, p-tert-Bu-C6H4SO2H, [Pd(MeCN)4](BF4)2 and 3,4,7,8-tetramethyl-1,10-phenanthroline afforded β-fluoro sulfone I (64% from E, 73% from Z, dr > 20:1).

The general formula of the complexes is Os(II)(N-N)2L-L, where N-N is either a bipyridine or a phenanthroline and L-L is either a phosphine or an arsine. New polypyridyl ligands synthesized are 4,4′-di(biphenyl)-2,2′-bipyridine (15) and 4,4′-di(di-Ph ether)-2,2′-bipyridine (16), and the 1,10-phenanthroline derivatives synthesized are 4,7-bis(p-methoxyphenyl)-1,10-phenanthroline (17), 4,7-bis(p-bromophenyl)-1,10-phenanthroline (18), 4,7-bis(4′-phenoxybiphen-4-yl)-1,10-phenanthroline (19), and 4,7-bis(4-naphth-2-ylphenyl)-1,10-phenanthroline (20). 4,4′-Diphenyl-2,2′-bipyridine (21) and 4,7-diphenyl-1,10-phenanthroline (22) were also used in these studies. Strong π-acid ligands used were 1,2-bis(diphenylarseno)ethane (23), cis-1,2-bis(diphenylphosphino)ethylene (24), and cis-1,2-vinylenebis(diphenylarsine) (25). 25 Was used for the 1st time in these types of luminescent Os complexes.

Brightness over 1400 cd/m2 for a double-layer device was reached, with a turn-on voltage of 8 V. The maximum external quantum efficiency was 0.64%. Commission Internationale de l’Eclairage (CIE) chromaticity coordinates (x, y) of the red electrophosphorescence from the complexes are (0.65, 0.34), which indicates pure red emission.
