Electropolymerized films of vinyl-substituted polypyridine complexes: Synthesis, characterization, and applications

A ruthenium(II) complex-based lysosome-targetable multisignal chemosensor for in vivo detection of hypochlorous acid

“…The choice of bipyridine-ruthenium(II) complex as a signal reporter is due to its rich PL and ECL properties reported in literature [12,27], and the choice of ferrocenyl moiety as a signal quencher is based on the consideration that ferrocenyl derivatives can effectively quench the luminescence through the PET process to corrupt the excited state of a luminophore [63]. We envisioned that the designed chemosensor, Ru-Fc, should be weakly luminescent owing to the quenching of ferrocenyl moiety, and a HOCl promoted specific oxidation reaction of hydrazine will cleave ferrocenyl moiety from Ru-Fc to turn on the luminescence of the bipyridineruthenium(II) complex.…”

A new multicolored and near-infrared electrochromic material based on triphenylamine-containing poly(3,4-dithienylpyrrole)

“…Introduction 43 Electrochromic materials, which exhibit reversible 44 absorption spectral changes by changing the applied poten- 45 tials, have attracted much attention in recent years [1][2][3][4][5][6][7][8]. 46 Originally, the research of electrochromic materials was 47 mainly focused on the optical changes in the visible region 48 (e.g., 350-750 nm), which had variable applications such as 49 smart windows, E-paper, optical switching devices, vari-50 able reflectance mirrors, and camouflage materials.…”

“…Actually, it is a chal- 70 lenge to obtain a material that can be switched from 71 highly transmissive state to highly absorbed state in a wide 72 range from UV-Vis to near-IR region. 73 Typical electrochromic materials are coordination com- 74 plexes, transition-metal oxides, organic molecules and 75 conjugated polymers [4][5][6]. Among with the Bruker SAINT package [36].…”

Electroluminochromic Materials and Devices Based on Metal Complexes

“…Ru II complexes have been extensively studied as electrochromic materials, [67][68][69][70] but there are few reports for them as ELC materials. ELC Ru II complexes were designedm ainly by the PeT mechanism or the mutual conversiono ft he different redox states of Ru II center.L ehn et al designed the luminescent Ru II complex Ru-1 ( Figure 6), which connected ar edox-activeq uinone moiety on one bipyridine ligand of photoactive Ru(bpy) 3 2 + core.…”
