Complementary, Cooperative Ditopic Halogen Bonding and Electron Donor-Acceptor π-π Complexation in the Formation of Cocrystals

Molecules, 2022
This study expands and combines concepts from two of our earlier studies. One study reported the complementary halogen bonding and π-π charge transfer complexation observed between isomeric electron rich 4-N,N-dimethylaminophenylethynylpyridines and the ...

Search for CP violation in the decay D+→π−π+π+ [PDF]

, 2013
A search for CP violation in the phase space of the decay D+→π−π+π+ is reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV.

New determination of the D0→K -π +π0 and D0→K -π +π +π - coherence factors and average strong-phase d [PDF]

, 2014
Measurements of the coherence factors (RKππ0 and R K3π) and the average strong-phase differences (δDKππ0 and δDK3π) for the decays D0→K -π +π0 and D0→K -π +π +π - are presented.

π-Stacking Stopper-Macrocycle Stabilized Dynamically Interlocked [2]Rotaxanes

Molecules, 2021
The synthesis of mechanically interlocked molecules is valuable due to their unique topologies. With π-stacking intercomponent interaction, e.g., phenanthroline and anthracene, novel [2]rotaxanes have been synthesized by dynamic imine clipping reaction ...
