Title: Synthesis of Zinc phthalocyanines within Zeolites
Efficient oxidation catalysts are critical for advancing technologies such as fuel cells and carbon dioxide reduction Transition metal phthalocyanines, such as zinc phthalocyanine (ZnPC) and zinc perfluorophthalocyanine (ZnF PC) , show promise due to their catalytic potential, despite challenges from aggregation-induced activity loss. This research focuses on synthesizing ZnPC and ZnF PC within zeolite Na-X (FAU) to leverage the zeolite′s confined environment to prevent aggregation and enhance the catalytic performance. Exptl. methodologies encompass ion exchange and melt synthesis techniques to synthesize ZnPC and ZnF PC within the zeolite matrix. Initial results demonstrate successful synthesis of ZnPC and ZnF PC in/on zeolite CBV780, based on characterization by diffuse reflec tance UV-Vis spectroscopy. To confirm that the phthalocyanines are made within the zeolite rather than on the outside of the zeolite, extensive washing using Soxhlet extraction is used to remove all phthalocyanines formed on the exterior of the zeolite. There are four fluorines in each phthalonitrile mol., and four phthalonitriles make a phthalocyanine, hence there are 16 fluorine atoms in a phthaloc yanine; "hexadecyl fluorophthalocyanine" would be correct, but is a mouthfull; hence perfluorophthalocyanine.  more » « less

    A comprehensive Scanning Tunneling Microscopy (STM)-driven ab initio investigation was conducted to explore the effects of peripheral substitution and central metalation on the molecular self-assembly of phthalocyanines on highly oriented pyrolytic graphite (HOPG). This study reports, for the first time, the self-assembly behavior of phthalocyanines with phenoxy and ethoxy substitutions and Co and Mg as central metals. Through periodic boundary simulations, we demonstrate that the peripheral substitutions significantly influence the energetic stability and monolayer structure, while central metal variations play a minor role. Our findings suggest that phthalocyanines with identical peripheral substitutions exhibit similar unit cell structures on Highly Oriented Pyrolytic Graphite (HOPG), regardless of the central metal. Furthermore, while substituent positional isomerism does not significantly impact the adsorption energy, the orientation of the peripheral substituents critically affects intermolecular interactions, influencing the stability of the monolayers. The study also reveals that octa-substituted phthalocyanines, such as H2Pc(OPh)8, form more stable, well-packed monolayers compared to tetra-substituted derivatives, like H2Pc(OEt)4, which exhibit phase segregation and disorder. Additionally, solvent molecules such as phenyl octane (PhOct) stabilize the disordered H2Pc(OEt)4monolayers by filling cavities between molecules. These results offer valuable insights into the design principles for engineering stable phthalocyanine monolayers, contributing to advancements in surface chemistry and materials science.

    OZ1, an RNA editing factor that controls the editing of 14 cytidine targets in Arabidopsis chloroplasts, contains two RanBP2-type zinc finger (Znf) domains. The RanBP2 Znf is a C4-type member of the broader zinc finger family with unique functions and an unusually diverse distribution in plants. The domain can mediate interactions with proteins or RNA and appears in protein types such as proteases, RNA editing factors, and chromatin modifiers; however, few characterized Arabidopsis proteins containing RanBP2 Znfs have been studied specifically with the domain in mind. In humans, RanBP2 Znf-containing proteins are involved in RNA splicing, transport, or transcription initiation. We present a phylogenetic overview of Arabidopsis RanBP2 Znf proteins and the functional niches that these proteins occupy in plants. OZ1 and its four-member family represent a branch of this family with major impact on the RNA biology of chloroplasts and mitochondria in Arabidopsis. We discuss what is known about other plant proteins carrying the RanBP2 Znf domain and point out how phylogenetic information can provide clues to functions of uncharacterized Znf proteins.

    Abstract Photoinduced electron transfer (PET) in newly assembled dyads formedviametal‐ligand axial coordination of phenylimidazole‐functionalized bis(styryl)BODIPY (BODIPY(Im)2) and zinc tetrapyrroles, that is, zinc tetratolylporphyrin (ZnP), zinc tetra‐t‐butyl phthalocyanine (ZnPc) and zinc tetra‐t‐butyl naphthalocyanine (ZnNc), in non‐coordinatingo‐dichlorobenzene (DCB) is investigated using both steady‐state and time‐resolved transient absorption techniques. The structure of the BODIPY(Im)2was identified by using single crystal X‐ray structural analysis. The newly formed supramolecular dyads were fully characterized by spectroscopic, computational and electrochemical methods. The binding constants measured from optical absorption spectral studies were in the range of ∼104 M−1for the first zinc tetrapyrrole binding and suggested that the two imidazole entities of bis(styryl)BODIPY behave independently in the binding process. The energy level diagram established using spectral and electrochemical studies suggested PET to be thermodynamically unfavorable in the ZnP‐bearing complex while for ZnPc‐ and ZnNc‐bearing complexes such a process is possible when zinc tetrapyrrole is selectively excited. Consequently, occurrence of efficient PET in the latter two dyads was possible to establish from femtosecond transient absorption studies wherein the electron transfer products, that is, the radical cation of zinc tetrapyrrole and the radical anion of BODIPY(Im)2, was possible to spectrally identify. From target analysis of the transient data, time constants of circa 3 ns for ZnPc⋅+:BODIPY⋅−and circa 0.5 ns for ZnNc⋅+:BODIPY⋅−were obtained indicating persistence of the radical ion‐pair to some extent. The electron acceptor property of bis(styryl)BODIPY in donor‐acceptor conjugates is borne out from the present study.

    An inexpensive, transparent, catalytic, and highly stable material is the holy grail for a dye sensitized solar cell (DSSC) cathode. Despite a near exponential increase in research effort on DSSC cathodes, materials approaching this ideal have yet to be found. Transparent cathodes allow for front and back illumination of the solar cell, enable alternative anode materials and cell designs, and are important both for fundamental research and commercialization of DSSCs. In this work, thin polymeric films of nickel tetraminophthalocyanine (NiTAPc) were tested as a catalytic cathode material in Co(Bipy)-mediated DSSCs. The thin films are highly transparent with a transmittance at 550 nm (T550) of over 95% while maintaining an R ct value below 1.3 Ω cm 2 . The NiTAPc films are inexpensive, fast and easy to generate, and stable to 2000 cyclic voltammetry cycles. Long-term film stability was not realized, and a rise in the R ct over time (days) occurred. However, poly-NiTAPc still represents one of the most transparent and catalytic materials reported to date. While historically phthalocyanines (Pc) have been studied as a dye/sensitizer, this first report of phthalocyanine use as a cathode material demonstrates they have utility on both sides of the DSSC.
