Electrochromic behavior of fac -tricarbonyl rhenium complexes

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, a series of tricarbonyl rhenium complexes, fac-Re(CO)3(Lx)Cl (x = 1-5), were synthesized and characterized by infrared spectroscopy, 1H NMR, 13C NMR, and high resolution mass spectrometry. Their stereochemistry was investigated by single crystal X-ray diffraction. Theoretical highest occupied molecular orbital and lowest unoccupied molecular orbital charge distributions of fac-Re(CO)3(Lx)Cl were calculated by density functional theory calculations. Their electrochemical and electrochromic properties were studied by cyclic voltammetry, UV-vis 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 less than 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 analogues.

Direct C-H Functionalization of Phenanthrolines: Metal- And Light-Free Dicarbamoylations

A direct method for C-H dicarbamoylations of phenanthrolines has been developed, which is capable of directly installing primary, secondary as well as tertiary amides. This is a significant improvement on the previous direct method, which was limited to primary amides. The metal-, light-, and catalyst-free Minisci-type reaction is cheap, operationally simple, and scalable. We demonstrate that the step efficiency toward dicarbamoylated phenanthroline targets can now be significantly improved.

Iron-Catalyzed Acyloxyalkylation of Styrenes Using Hypervalent Iodine Reagents

Iron-catalyzed acyloxyalkylation of styrene derivatives using hypervalent iodine reagents was achieved. The acyloxyalkylation reaction proceeded using various types of styrenes and hypervalent iodine reagents. The acyloxyalkylated products were obtained in moderate to good yields without loss of the functional groups. The reaction proceeded via the formation of radical species derived from hypervalent iodine reagents by decarboxylation.

Synthesis and binding properties of dendritic oxybathophenanthroline ligands towards copper(II)

Dendritic oxybathophenanthroline ligands (generation 0 to 3) have been synthesized by treatment of 4,7-bis(4′-hydroxyphenyl)-1,10-phenanthroline with the corresponding Frechet-type dendrons carrying a benzylic bromide function at the focal point. The comp
