A series of platinum diimine-dithiolene complexes with a 5,6-dihydro-1,4-dithiin-2,3-dithiolato (dddt2-) dithiolene ligand and bipyridine carrying tris-alkoxyphenyl fragments connected through an ester linker (bpyCn, n = 8, 12, 16, 10(s), 20) (Scheme 1) has been developed. The mesomorphic properties the ligands have investigated by combination DSC,...
The response to the high demand for decreasing the amount of CO2 in the atmosphere, a new polyaminal-based polymer network was designed and successfully prepared through one-pot polycondensation reaction of melamine and [2,2′-Bipyridine]-5,5′-dicarbaldehyde. The formation of the polymer structure was confirmed by FT-IR, solid-state 13C NMR, and pow...

A bipyridine‐based covalent organic framework photocatalyst (COF‐TfpBpy) showed excellent activity for H2O2 photosynthesis with a solar‐to‐chemical conversion efficiency of 0.57 % at 298 K and 1.08 % at 333 K. The photocatalytic process involves a 2 e− water oxidation and 2 e− oxygen reduction from water and air. The photocatalytic H2O2 solution ca...
The synthesis of novel macrocyclic N-bis-imidazolium-bis-heterocyclic carbenes (NHCs) with rigid and constrained structures to improve the stability of their transition metal coordination complexes in order to obtain efficient photosensitizers is reported. Two pathways have been developed for the preparation of coronocarbenes (L1-L3) containing bip...
Using sunlight as a renewable source of energy to promote carbon dioxide (CO2) conversion is an interesting approach to address sustainable chemicals and fuels production as well as mitigation of climate change. However, in most photocatalytic systems, the utilization of a homogeneous photosensitizer represents a key limitation for long-term reacti...
Chapter 1: A new, chelating, monoanionic bis(N-heterocyclic carbene)borate mesityl ligand was synthesized and used to prepare a thorium bis(iodo) complex as well as a direduced-bpy derivative (Th-NHC-bpy). Complete Active Space Self-Consistent Field (CASSCF) calculations suggested the involvement of a multi-configurational open-shell singlet in the...
The charged, electroactive bipyridine-helicene-ruthenium(III) complex [4].+,PF6− has been prepared from 3-(2-pyridyl)-4-aza[6]helicene and a Ru-bis-(β-diketonato)-bis-acetonitrile precursor (β-diketonato: 2,2,6,6-tetramethyl-3,5-heptanedionato). Its chiroptical properties (electronic circular dichroism and optical rotation) were studied both experi...

Magnetic iron oxide nanoparticles doped with samarium were prepared by solvothermal polyol method. An introduction of 2,2'-bipyridine during the synthesis reduces the particle diameter to about 9nm in average. The difference in physical and magnetic properties of the samples prepared with and without capping agent was outlined on the basis of compl...

Two hetero-tritopic bridging ligands L1 and L2 based on 2,2′-bipyridine and 1,10-phenanthroline moieties, and their corresponding Ru(II) complexes [{Ru(bpy)2}3(µ3−L1)](PF6)6 and [{Ru(bpy)2}3(µ3−L2)](PF6)6 (bpy = 2,2′-bipyridine), were synthesized. The molecular structures of both complexes were deduced by 1H NMR, ESI-MS, ESI-HRMS, elemental analyse...
