Novel metal-template assembled highly-functionalized cyanoporphyrazine ytterbium and vanadium complexes for potential photonic and optoelectronic applications

Novel regular polyimide-graft -(polymethacrylic acid) brushes: Synthesis and possible applications as nanocontainers of cyanoporphyrazine agents for photodynamic therapy

“…Yb[pz(4‐FC 6 H 4 ) 4 (CN) 4 ](OH)·3H 2 O was prepared using the original synthetic approach reported recently . The starting compound 2‐(4‐fluorophenyl)‐1,1,2‐tricyanoethylene was synthesized according to the literature method …”

Novel PEG-organized biocompatible fluorescent nanoparticles doped with an ytterbium cyanoporphyrazine complex for biophotonic applications

“…It should be noted that the red fluorescence quantum yield of IV in THF solution is very low (f = 10 À3 relative to Rhodamine 6G) unlike that in solid polymeric matrices. 3 Investigations of the luminescent properties of RFS1 and RFS2 emission revealed a significant increase in RSF1 red emission quantum yield in comparison with that for IV in THF solution, but it nevertheless remained very minor (f { 1) (Fig. S4, ESIw; Table 2).…”

“…1). 3 Because of enhanced biological tissue penetrability at longer wavelengths the reported compounds may be interesting as potential PDT photosensitizers characterized by intense absorption in the red.…”

“…S1(A), ESIw) with intense luminescence over a wide range of wavelengths covering the biologically relevant optical window of tissue transparency (630-1000 nm). 3 This compound presumably has a binuclear structure, its axial Yb(TCNVB) 3 fragment forming a disordered polynuclear coordination polymer network with metal cations bridged through the nitrile nitrogen atom. It exhibits strongly enhanced chemical and hydrolytic stability in comparison with complexes I-III.…”
