This review highlights the most relevant works on phthalocyanines, porphyrins and other porphyrinoids as components of perovskite solar cells from last four years acting hole transporting materials, additives, interlayers.
Despite the potential of photodynamic therapy (PDT) in cancer treatment, development efficient and photostable photosensitizing molecules that operate at long wavelengths light has become a major hurdle. Here, we report for first time an Ir(III)-phthalocyanine conjugate (
Cu and Zn based phthalocyanines with 4-<italic>tert</italic>-octylphenoxy-substituted functional groups were synthesized showed high solubility in a range of organic solvents, they integrated perovskite solar cells.

Dopant-free metal phthalocyanines are viable alternatives to the classical 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) in perovskite solar cells (PSCs), due their appealing optoelectrical properties and chemical stability. However, low carrier concentration, transportability, narrow band gap limit application. Here, we designed investigated six innovative asymmetrically substituted (MPcs, M = Zn or Cu), established correlation among electronic...
Abstract Molecular catalysts offer a unique opportunity to implement different chemical functionalities steer the efficiency and selectivity for CO 2 reduction instance. Metalloporphyrins metallophthalocyanines are under high scrutiny since their most classic derivatives tetraphenylporphyrin (TPP) parent phthalocyanine (Pc), have been used as molecular platform install, hydrogen bonds donors, proton relays, cationic fragments, incorporation in MOFs COFs, enhance catalytic power of these...
A new zinc phthalocyanine-zinc porphyrin dyad (ZnPc-ZnP) fused through a pyrazine ring has been synthesized as receptor for imidazole-substituted C60 (C60Im) electron acceptor. Self-assembly via metal-ligand axial coordination and the pertinent association constants in solution were determined by 1H-NMR, UV-Vis fluorescence titration experiments at room temperature. The designed host was able to bind up two C60Im acceptor guest molecules yield C60Im:ZnPc-ZnP:ImC60 donor-acceptor...
Abstract A supramolecular triad composed of a fused zinc phthalocyanine‐free‐base porphyrin dyad (ZnPc‐H 2 P) coordinated to phenylimidazole functionalized C 60 via metal‐ligand axial coordination was assembled, as photosynthetic antenna‐reaction centre mimic. The process self‐assembly resulting into the formation Im:ZnPc‐H P probed by proton NMR, UV‐Visible and fluorescence experiments at ambient temperature. geometry electronic structures were deduced from DFT calculations performed...
The synthesis and characterization of different conjugated phthalocyanine–perylenemonoimidebenzimidazole [ZnPc-PBIm(OR)4] nonconjugated phthalocyanine–perylenediimide [ZnPc-PDI(OR)4] dyads are carried out. UV–vis, 1H NMR, electrochemistry measurements reveal the interaction between perylene phthalocyanine moieties in ground state hybrid lack one. Ultrafast transient absorption show that a with substantial charge-transfer character is formed both compounds, but rates for formation...
Star-shaped triphthalocyaninehexaazatriphenylene 1 was synthesized via condensation between a new building block 1,2-diaminophthalocyanine and cyclohexanehexaone. Compound represents the largest star-shaped phthalocyanine-fused hexaazatriphenylene reported so far. This largely expanded phthalocyanine shows good solubility has strong tendency to aggregate both in solution on surface, indicating its potential as an active component organic electronic devices.
The textbook explanation that P680 pigments are the red limit to drive oxygenic photosynthesis must be reconsidered by recent discovery chlorophyll f (Chlf)-containing Photosystem II (PSII) absorbing at 727 nm can water oxidation. Two different families of unsymmetrically substituted Zn phthalocyanines (Pc) in 700-800 spectral window and containing a fused imidazole-phenyl substituent or imidazole-hydroxyphenyl group have been synthetized characterized as bioinspired model Chlf/TyrosineZ...

A series of pyrazinepyrene-fused zinc phthalocyanines (ZnPc-Pyrn) have been newly synthesized by reacting quinoxaline and the corresponding diamino-functionalized as a new class π-extended phthalocyanine systems. Bathochromically shifted absorption function number pyrazinepyrene entities due to extended π-conjugation quenched fluorescence presence fused were witnessed. The electronic structures these probed systematic computational electrochemical studies, while excited-state properties...

Das Chlorophyll f (Chl f) enthaltende Photosystem II, das im fernen Rot absorbiert, überwindet “rote Limit” der Photosynthese, vom a bei 680 nm festgelegt ist, und vermittelt die Wasseroxidation 727 nm. Ein Phthalocyanin-Chromophor mit ähnlichen Absorptionseigenschaften wie Chl wurde an ein TyrosinZ/Histidin-Modell gekoppelt – dem Aminosäurenpaar, als Elektronenrelais zwischen wasseroxidierenden Mn4Ca-Komplex fungiert.
