Near-infrared dual luminescence from an extended zinc porphyrin.

چکیده
The photophysical characterization of an extended zinc porphyrin is reported. Fusion of bis-tetraazaanthracene on the porphyrin ring causes an unusual dual luminescence ascribed to two non-equilibrated singlet excited states.

Synthesis and near-infrared luminescence of a deuterated conjugated porphyrin dimer for probing the mechanism of non-radiative deactivation.
beta,meso,beta-Fused porphyrin oligomers have many attractive photophysical features such as strong absorption in the near-IR at wavelengths greater than 1000 nm, and high two-photon cross sections. However their ultrafast S(1)-S(0) deactivation (k(d) > 10(11) s(-1)) limits potential applications. We have synthesised a deuterated fused porphyrin dimer to test whether deuteration influences the ...
متن کاملTunable Phosphorescent NIR Oxygen Indicators Based on Mixed Benzo- and Naphthoporphyrin Complexes
A series of π-extended phosphorescent palladium(II) and platinum(II) porphyrin complexes were synthesized, in which additional benzene rings are fused radially onto at least one of the four peripheral benzo groups. The photophysical properties of the metalloporphyrins palladium(II)-meso-tetra-(4-fluorophenyl)mononaphthotribenzoporphyrin (Pd1NF), cis-palladium(II)-meso-tetra-(4-fluorophenyl)dibe...
متن کاملExtended photoresponse and multi-band luminescence of ZnO/ZnSe core/shell nanorods
Aligned ZnO/ZnSe core/shell nanorods (NRs) with type-II energy band alignment were fabricated by pulsed laser deposition of ZnSe on the surfaces of hydrothermally grown ZnO NRs. The obtained ZnO/ZnSe core/shell NRs are composed of wurtzite ZnO cores and zinc blende ZnSe shells. The bare ZnO NRs are capable of emitting strong ultraviolet (UV) near band edge (NBE) emission at 325-nm light excitat...
متن کاملNear Infrared-Emitting Cr3+/Eu3+ Co-doped Zinc Gallogermanate Persistence Luminescent Nanoparticles for Cell Imaging
Near infrared (NIR)-emitting persistent luminescent nanoparticles have been developed as potential agents for bioimaging. However, synthesizing uniform nanoparticles with long afterglow for long-term imaging is lacking. Here, we demonstrated the synthesis of spinel structured Zn3Ga2Ge2O10:Cr3+ (ZGGO:Cr3+) and Zn3Ga2Ge2O10:Cr3+,Eu3+ (ZGGO:Cr3+,Eu3+) nanoparticles by a sol-gel method in combinati...
متن کاملVisible and near-infrared luminescence of helical zinc(II)-lanthanide(III) trinuclear complexes having acyclic Bis(N2O2) oxime ligand
Luminescent properties of helical zinc(II)-lanthanide(III) complexes [LZn2Ln] (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu), which are obtained by the reaction of acyclic bis(N2O2) tetraoxime ligand with zinc(II) and lanthanide(III) ions, were studied. The H NMR spectral study indicated that the complexes [LZn2Ln] adopt a helical conformation in solution, where two terminals are...
