New metal-free phthalocyanines (8–9) fused in peripheral positions with four tetraazadithiahexaoxa supercryptands were synthesized by tricyclotetramerization of isoindolinediimine derivatives of supercryptands (6–7). Metallophthalocyanines (10–11) were prepared by the reaction of the metal-free phthalocyanines with metal salts or cyclotetramerization of dicyano compounds (4–5) and anhydrous sal...

Metallophthalocyanines (MPc-o-Cou, M = Fe, Co, Ni, and Cu) with fourth period metal ions have been successfully applied as a sensitizer coupled with rubrene (Rub) in photon upconversion based on triplet-triplet annihilation. An upconversion quantum yield (ϕPUC) of up to 4.82% was observed in the CoPc-o-Cou : Rub couple. The absorption and phosphorescence emission spectra showed that the Q bands...

Several conjugates of metallophthalocyanines with deoxyribooligonucleotides were synthesized to investigate sequence-specific modification of DNA by them. Oligonucleotide parts of these conjugates were responsible for the recognition of selected complementary sequences on the DNA target. Metallophthalocyanines were able to induce the DNA modification: phthalocyanines of Zn(II) and Al(III) were ...

Several metalloporphyrins, particularly highly chlorinated water soluble meso-tetraphenylporphyrins, have been shown to be good biomimetics of the lignin peroxidases which degrade lignin in vivo. Metal complexes of the water soluble phthalocyaninetetrasulfonic acid have been examined as catalysts for the oxidation of lignin since the phthalocyanines are readily available and inexpensive. The co...

In this work, previously synthesized tetra-chalcone-substituted metallophthalocyanines (MPcs) containing Ni(II), Zn(II), Co(II), and Cu(II) in the inner core were investigated anticholinergic activities against Alzheimer's disease (AD). The MPcs evaluated for their inhibition of acetylcholinesterase (AChE) butyrylcholinesterase (BChE) using original Ellman's colorimetric procedure. Against thes...
