Electronic Circular Dichroism Imaging (ECDi) Casts a New Light on the Origin of Solid-State Chiroptical Properties
Górecki, Marcin; Lipparini, Filippo; Albano, Gianluigi; Jávorfi, Tamás; Hussain, Rohanah; Siligardi, Giuliano; Pescitelli, Gennaro; Di Bari, Lorenzo (Wiley, 2022)Solid-state ECD (ss-ECD) spectra of a model microcrystalline solid, finasteride, dispersed into a KCl pellet were recorded by using the synchrotron radiation source at the Diamond B23 beamline. Scanning a surface of 36 mm2 ... -
A Holistic Approach to Determining Stereochemistry of Potential Pharmaceuticals by Circular Dichroism with β-Lactams as Test Cases
Górecki, Marcin; Frelek, Jadwiga (MDPI, 2022)This paper’s main objective is to show that many different factors must be considered when solving stereochemical problems to avoid misleading conclusions and obtain conclusive results from the analysis of spectroscopic ... -
On-Surface Stereochemical Characterization of a Highly Curved Chiral Nanographene by Noncontact Atomic Force Microscopy and Scanning Tunneling Microscopy
Zhong, Qigang; Barát, Viktor; Csókás, Dániel; Niu, Kaifeng; Górecki, Marcin; Ghosh, Animesh; Björk, Jonas; Ebeling, Daniel; Chi, Lifeng; Schirmeisen, André; Stuparu, Mihaiela C. (Chinese Chemical Society, 2023)A highly distorted chiral nanographene structure composed of triple corannulene-fused [5]helicenes is prepared with the help of the Heck reaction and oxidative photo-cyclization with an overall isolated yield of 28%. ... -
Spatially resolved chiroptical study of thin films ofbenzo[1,2-b:4,5-b’]dithiophene-based oligothiophenes bysynchrotron radiation electronic circular dichroism imaging(SR-ECDi) technique
Albano, Gianluigi; Górecki, Marcin; Jávorfi, Tamás; Hussain, Rohanah; Siligardi, Giuliano; Pescitelli, Gennaro; Di Bari, Lorenzo (Wiley, 2022)The study of the chiroptical properties of thin-film samples of two chiral benzo[1,2-b:4,5-b’]dithiophene-based oligothiophenes with optoelectronic properties was car-ried out at Diamond B23 beamline using the synchrotron ... -
A Unique and Stable Polyproline I Helix Sorted out from Conformational Equilibrium by Solvent Polarity
Pollastrini, Matteo; Pasquinelli, Luca; Górecki, Marcin; Balzano, Federica; Cupellini, Lorenzo; Lipparini, Filippo; Barretta, Gloria Uccello; Marchetti, Fabio; Pescitelli, Gennaro; Angelici, Gaetano (American Chemical Society, 2022)Polyproline I helical structures are often considered as the hidden face of their most famous geminal sibling, Polyproline II, as PPI is generally spotted only within a conformational equilibrium. We designed and synthesized ...
