Inorganic metal halide perovskites such as CsPbI3 are promising for high-performance, reproducible, and robust solar cells. However, inorganic sensitive to humidity, which causes the transformation from black phase yellow δ, non-perovskite phase. Such instability has been a significant challenge long-term operational stability. Here, surface dimensionality reduction strategy is reported, using 2-(4-aminophenyl)ethylamine cation construct Dion-Jacobson 2D that covers of 3D perovskite...
A two-step route to strongly absorbing and efficiently orange deep red fluorescent, doubly B/N-doped, ladder-type pyrrolo[3,2-b]pyrroles has been developed. We synthesize study a series of derivatives these four-coordinate boron-containing, nominally quadrupolar materials, which mostly exhibit one-photon absorption in the 500-600 nm range with peak molar extinction coefficients reaching 150 000, emission 520-670 fluorescence quantum yields 0.90. Within family ultrastable dyes even small...
Abstract Stability issues could prevent lead halide perovskite solar cells (PSCs) from commercialization despite it having a comparable power conversion efficiency (PCE) to silicon cells. Overcoming drawbacks affecting their long‐term stability is gaining incremental importance. Excess iodide (PbI 2 ) causes degradation, although aids in crystal growth and defect passivation. Herein, we synthesized functionalized oxo‐graphene nanosheets (Dec‐oxoG NSs) effectively manage the excess PbI ....

The aims of this study were to investigate the potential utilising molecularly imprinted polycarbazole layers detect highly toxic picric acid (PA) and provide information about their performance. Quantum chemical calculations showed that strong interactions occur between PA carbazole (bond energy approximately 31 kJ/mol), consistent with theoretical requirements for effective molecular imprinting. performance sensors, however, was found be limited, observed imprinting factor values (PCz)...
Conductive π-conjugated polymers were electrochemically generated from a variety of donor–acceptor pyrroles containing fused perimidine subunits. Alternating oxidative and reductive polarization these precursors induces multidirectional coupling involving both acenaphtho[1,2-c]pyrrole moieties, producing cross-linked polymeric structures. Chemical oxidation experiments computational analyses spin densities in the charged pyrrole intermediates indicate that formation inter-perimidine linkages...
Using 3-phenyl-5-(5-phenyl-1 H -pyrrol-3-yl)-1,2,4-oxadiazole, BODIPYs with the oxadiazole groups at 1,7-positions were prepared and their photophysical properties characterized.
During research on cross-linked conducting polymers, double-functionalized monomers were synthesized. Two subunits potentially able to undergo oxidative coupling used—perimidine and, respectively, carbazole, 3,6-di(hexylthiophene)carbazole or 3,6-di(decyloxythiophene)carbazole; alkyl and alkoxy chains as groups supporting molecular ordering 14H-benzo[4,5]isoquinone[2,1-a]perimidin-14-one segment promoting CH⋯O interactions π–π stacking. Electrochemical, spectroelectrochemical, density...
The introduction of electron donating groups or withdrawing into the phenyl ring at meso position 1,7-aroyl BODIPY significantly influences fluorescence quantum yield.
We successfully synthesized a stable electroactive perinone polymer by electropolymerization of 3,4:9,10-bis(1,8-naphthapyrimidine)-1,6,7,12-tetrakis(1,1,3,3-tetramethylobutylphenoxy)perylene (NPP). The p(NPP) exhibited distinct redox proces, with reduction at -1.20 V and oxidation 0.60 (vs. ferrorocene/ferrocenium couple). Spectroscopic computational analyses confirmed structural similarity the to its monomeric form, revealing perimidine unit involved in electrocoupling. Our thorough...
<title>Abstract</title> We present a new simple approach for electrochemical synthesis of semi-condensed ambipolar perinone polymers with phthaloperine (<bold>p1</bold>) or phenanthroline (<bold>p2</bold>) skeleton from available and cheap perimidine precursors. Polymerization derivatives varies in efficiency depending on the monomer, but overall is highly efficient, especially when electropolymerization used. Electrooxidation well controllable provides certain characteristic share bonds...
This study explores the potential of copper-doped nickel oxide (Cu:NiO) as a hole transport layer (HTL) in flexible photovoltaic (PV) devices using combined first-principles and finite element analysis approach. Density functional theory (DFT) calculations reveal that Cu doping introduces additional states valence band NiO, leading to enhanced charge transport. Notably, Cu:NiO exhibits direct gap (reduced from 3.04 eV NiO 1.65 stable supercell structure), facilitating efficient transfer...
