BDPA-Nitroxide Biradicals Tailored for Efficient Dynamic Nuclear Polarization Enhanced Solid-State NMR at Magnetic Fields up to 21.1 T

David Lyndon Emsley, Aaron James Rossini, Dominik Józef Kubicki, Arthur César Pinon, Moreno Lelli, Georges Guévork Jean-Jacques Menzildjian, David Benjamin Roger Antoine Gajan

Dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) has developed into an invaluable tool for the investigation of a wide range of materials. However, the sensitivity gain achieved with many polarizing agents suffers from an unf ...

Addition of adamantylammonium iodide to hole transport layers enables highly efficient and electroluminescent perovskite solar cells

Michael Graetzel, David Lyndon Emsley, Wolfgang Richard Tress, Jovana Milic, Dominik Józef Kubicki, Mohammad Mahdi Tavakoli

The efficiency of perovskite solar cells (PSCs) is currently limited by non-radiative recombination losses. One potential loss channel consists of electrons recombining at the interface with the hole transport layer (HTL). We synthesized adamantylammonium ...

Surface-Enhanced NMR Spectroscopy

Dominik Józef Kubicki

Dynamic Nuclear Polarization (DNP) is currently one of the most efficient ways of enhancing sensitivity in solid-state NMR experiments. The DNP protocol consists in doping a sample with a small amount of para-magnetic species, typically nitroxide biradical ...

Phase Segregation in Cs-, Rb- and K-Doped Mixed-Cation (MA)(x)(FA)(1-x)Pbl(3) Hybrid Perovskites from Solid-State NMR

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Daniel Prochowicz, Dominik Józef Kubicki, Albert Hofstetter

Hybrid (organic-inorganic) multication lead halide perovskites hold promise for a new generation of easily processable solar cells. Best performing compositions to date are multiple-cation solid alloys of formamidinium (FA), methylammonium (MA), cesium, an ...

Cation Dynamics in Mixed-Cation (MA)(x)(FA)(1-x)PbI3 Hybrid Perovskites from Solid-State NMR

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Péter Kalman Péchy, Dominik Józef Kubicki, Daniel Prochowicz, Albert Hofstetter

Mixed-cation organic lead halide perovskites attract unfaltering attention owing to their excellent photovoltaic properties. Currently, the best performing perovskite materials contain multiple cations and provide power conversion efficiencies up to around ...

Rational design of dinitroxide biradicals for efficient cross-effect dynamic nuclear polarization

David Lyndon Emsley, Aaron James Rossini, Dominik Józef Kubicki

A series of 37 dinitroxide biradicals have been prepared and their performance studied as polarizing agents in cross-effect DNP NMR experiments at 9.4 T and 100 K in 1,1,2,2-tetrachloroethane (TCE). We observe that in this regime the DNP performance is str ...
