Alcohol-Soluble Zwitterionic 4-(Dimethyl(pyridin-2-yl)ammonio)butane-1-sulfonate Small Molecule as a Cathode Modifier for Nonfullerene Acceptor-Based Organic Solar Cells.

ACS Applied Materials and Interfaces, 2021
A new zwitterionic small molecule 4-(dimethyl(pyridin-2-yl)ammonio)butane-1-sulfonate (PAS), synthesized from 2-dimethylaminopyrindine (2-DMAP), was developed for the ITO cathode modifier. PAS and 2-DMAP dissolved in methanol can form a thin layer on ITO

Structure and Internal Motions of a Multifunctional Alcohol-Water Complex: Rotational Spectroscopy of the Propargyl Alcohol···H2O Dimer.

Journal of Physical Chemistry A, 2021
We have studied the rotational spectra of the propargyl alcohol (PA)-water complex using a pulsed-nozzle Fourier transform microwave spectrometer. A hydrogen-bonded ring structure is observed.

Teaching old anchoring group new tricks: enabling low-cost, eco-friendly hole-transporting materials for efficient and stable perovskite solar cells.

Journal of the American Chemical Society, 2020
As a key component in perovskite solar cells (PVSCs), hole-transporting materials (HTMs) have been extensively explored and studied. Aiming to meet the requirements for future commercialization of PVSCs, HTMs which can enable excellent device performance

An Alternative Reaction Course in O-Glycosidation with O-Glycosyl Trichloroacetimidates as Glycosyl Donors and Lewis Acidic Metal Salts as Catalyst: Acid-Base Catalysis with Gold Chloride-Glycosyl Acceptor Adducts.

Journal of the American Chemical Society, 2015
Gold(III) chloride as catalyst for O-glycosyl trichloroacetimidate activation revealed low affinity to the glycosyl donor but high affinity to the hydroxy group of the acceptor alcohol moiety, thus leading to catalyst-acceptor adduct formation.

Tolerance zones: a pragmatic approach to respond to problems related to open alcohol and drug scenes in Bremen/Germany

Drugs and alcohol today, 2021
Purpose This study aims to describe and analyse an approach in the city of Bremen (Germany) to establish streetwork-supported tolerance zones for local open drug and alcohol scenes to reduce related disorder and nuisance in public spaces.
