Structure and Phase Transition of 4,7-Bis-(4′-cyano-biphenyl-4-yl)-[1, 10]phenanthroline

4,7-Bis-(4′-cyano-biphenyl-4-yl)-[1, 10]phenanthroline (cnbiphphen) is synthesized from a palladium mediated coupling between 4-cyanobenzene boronic acid and 4,7-bis(4-bromophenyl)-[1,10]phenanthroline. The single crystal X-ray structure was measured at b

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.

Properties and structure of two fluorinated 1,10-phenanthrolines

We report the synthesis, X-ray structure, absorbance and emission of 4,7-bis(4-fluorophenyl)-1,10-phenanthroline and 4,7-bis-(4′-trifluoromethyl-biphenyl-4-yl)-1,10-phenanthroline. 4,7-Bis(4-fluorophenyl)-1,10-phenanthroline was synthesized by successive Skraup reactions and features absorbance at 274 nm and emission at 384 nm while 4,7-bis-(4′-trifluoromethyl-biphenyl-4-yl)-1,10-phenanthroline featured absorbance at 283 nm and emission at 400 nm. The structures show molecular stacking of the phenyl groups and phenanthroline structure and longitudinal fluorine atom associations within the crystal lattice. Furthermore, the three fused rings of the 4,7-bis(4-fluorophenyl)-1,10-phenanthroline unit exhibited torsion up to 13.97(9)° throughout the crystal lattice whereas no torsion is observed for 4,7-bis-(4′-trifluoromethyl-biphenyl-4-yl)-1,10-phenanthroline.

Phenanthrolines

The present invention relates to phenanthroline compounds and to electroluminescent (EL) devices comprising the phenanthroline compounds.
