As the hole transport layer (HTL) for perovskite solar cells (PSCs), poly(3-hexylthiophene) (P3HT) has been attracting great interest due to its low-cost, thermal stability, oxygen impermeability, and strong hydrophobicity. In this work, a new doping strategy is developed P3HT as HTL in triple-cation/double-halide ((FA1-x-y MAx Csy )Pb(I1-x Brx )3 ) mesoscopic PSCs. Photovoltaic performance stability of show remarkable enhancement using composition three dopants Li-TFSI, TBP, Co(III)-TFSI...
The commercialization of perovskite solar cells (PSCs) has seen an important limitation in the instability that afflicts hole-transporting layer (HTL), namely, spiro-OMeTAD, used high-efficiency devices. latter is, turn, relatively expensive, undermining sustainability device. Its replacement with polymeric scaffolds, such as poly(3-hexylthiophene) (P3HT), will solve these issues. In this work, we adopted various sustainable synthetic methods to obtain four different homemade P3HTs molecular...
Recognition of enantiomers is one the most arduous challenges in chemical sensor development. Although several chiral systems exist, their effective exploitation as sensitive layer sensors hampered by practical implications that hinder stereoselective recognition solid state. In this paper, we report a new methodology to efficiently prepare films, using hybrid material approach where porphyrin derivatives are grafted onto zinc oxide nanoparticles. Circular dichroism (CD) evidences...

The coupling of semiconductors with organic molecules results in a class sensors whose chemoresistive properties are dictated by the nature dyes. Organic generally reduce conductivity, but case optically active dyes, such as porphyrinoids, conductivity is restored illumination visible light. In this paper, we investigated gas sensing ZnO nanoparticles coated porphyrins and corroles. Under light illumination, resistance these materials increases adsorption volatile compounds decreases when...
The solvent driven aggregation of porphyrin derivatives, covalently linked to a L- or D-prolinate enantiomer, results in the stereospecific formation species featuring remarkable supramolecular chirality, as consequence reading and amplification stereochemical information stored proline-appended group. Spectroscopic, kinetic, topographic SEM studies gave important on processes, structures final chiral architectures. obtained may be seeds for construction stereoselective sensors aiming at...
In this work, porous complex and metal-free cathodes based on a (La0.6Sr0.4) (Cr0.5Mn0.5) O3 (LSCM) screen-printed backbone infiltrated with Ce0.9Gd0.1O2 (GDC) were fabricated for solid oxide electrolyzer cells. GDC infiltration has been optimized by structural microstructural investigation tested electrochemical measurements in CO/CO2 mixtures. Infiltrated electrodes non-aqueous solution showed the best electro-catalytic activity towards CO2 reduction, exhibiting much lower polarization...
Supramolecular chirality is one of the most important issues in different branches science and technology, as stereoselective molecular recognition, catalysis, sensors. In this paper, we report on self-assembly amphiphilic porphyrin derivatives possessing a chiral information periphery macrocycle (i.e., D- or L-proline moieties), presence amines co-solute, such benzylamine derivatives. The aggregation process, steered by hydrophobic effect, has been studied aqueous solvent mixtures combined...
Abstract Two different copper and gallium arylcorroles have been functionalized using the Vilsmeier–Haack reaction. A further Knoevenagel reaction with cyanoacetic acid was performed on both complexes, affording desired products yields above 90 %. The newly synthesized compounds thoroughly characterized by a combination of spectroscopic methods, optical analyses, X‐ray crystallography. Moreover, they tested as anchoring groups for hydrothermal synthesis ZnO nanoparticles. morphology...
