Pyrene-Connected Tetraimidazolylidene Complexes of Iridium and Rhodium. Structural Features and Catalytic Applications
(American Chemical Society, 2018)
A pyrene-connected tetra-imidazolium salt has been prepared starting from
commercially available 1,3,6,8-tetrabromopyrene, and used as tetra-NHC precursor in the
preparation of tetranuclear Rh(I) and Ir(I) complexes. The ...
Synthesis and Catalytic Applications of Heterobimetallic Carbene Complexes Obtained via Sequential Metalation of Two Bisazolium Salts
(American Chemical Society, 2019)
A simple sequential metalation approach starting
from the imidazolium/benzimidazolium salt 4(I)2 yielded the
heterobimetallic RhIII/M (M = PdII, IrI
, AuI
, RuII) complexes [6]−
[9]. Alternatively, a symmetrical ...
Unravelling the role of vacancies in lead halide perovskite through electrical switching of photoluminescence
(Nature Research, 2018)
We address the behavior in which a bias voltage can be used to switch on and off the
photoluminescence of a planar film of methylammonium lead triiodide perovskite (MAPbI3)
semiconductor with lateral symmetric electrodes. ...
Redox-Switchable Cycloisomerization of Alkynoic Acids with Napthalenediimide-Derived N-Heterocyclic Carbene Complexes
(Wiley, 2021-09-01)
Two naphthalene-diimide (NDI) bis-imidazolium salts have been used as N-heterocyclic carbene (NHC) precursors for the preparation of NDI-functionalized complexes of rhodium and iridium of general formula [MCl(NDI-NHC)(COD)] ...
Unique Curve for the Radiative Photovoltage Deficit Caused by the Urbach Tail
(American Chemical Society, 2021-08-12)
The photovoltage Voc of high-performance solar cells such as GaAs
and metal halide perovskites is affected by the exponential Urbach tail in the
absorption spectrum, with an energy parameter EU. It has been observed ...
Quantum dot-sensitized solar cells
(Royal Society of Chemistry, 2018)
Quantum dot-sensitized solar cells (QDSCs) have emerged as a promising candidate for next-generation solar cells due to the distinct optoelectronic features of quantum dot (QD) light-harvesting materials, such as high ...
Probing the 3‐step Lithium Storage Mechanism in CH3NH3PbBr3 Perovskite Electrode by Operando‐XRD Analysis
(Wiley, 2019-01-19)
Organic‐inorganic hybrid materials have gradually become one of the most actively studied research fields due to their fascinating properties. The reaction between lithium and organic‐inorganic halide perovskite has just ...
1H-1,2,3-Triazol-5-ylidenes: Readily Available Mesoionic Carbenes
(American Chemical Society, 2018)
Classical carbenes are usually described as neutral compounds featuring a divalent carbon with only six electrons in their valence shell. It was only in 1988 that our group prepared the first isolable example, in which the ...
Tunable light emission by exciplex state formation between hybrid halide perovskite and core/shell quantum dots: Implications in advanced LEDs and photovoltaics
(American Association for the Advancement of Science, 2016)
We report the first observation of exciplex state electroluminescence due to carrier injection between the hybrid lead halide perovskite (MAPbI3–xClx) and quantum dots (core/shell PbS/CdS). Single layers of perovskite (PS) ...
2D PEA2SnI4 Inkjet-Printed Halide Perovskite LEDs on Rigid and Flexible Substrates
(American Chemical Society, 2022)
Lead-free PEA2SnI4-based perovskite LEDs are successfully inkjet-printed on rigid and flexible substrates. Red-emitting devices (λmax = 633 nm) exhibit, under ambient conditions, a maximum external quantum efficiency ...
