چکیده
The encapsulation of the tetracationic palladium metallosquare with four pyrene-bis-imidazolylidene ligands [1]4+ a series organic molecules was studied by Electrospray ionization Travelling Wave Ion-Mobility Mass Spectrometry (ESI TWIM-MS). method allowed to determine Collision Cross Sections (CCSs), which were used assess size changes experienced host upon guest molecules. When fullerenes as guests, is expanded ?CCS 13 Å2 and 23 Å2, for C60 or C70, respectively. metallorectangle also polycyclic aromatic hydrocarbons (PAHs) naphthalenetetracarboxylic diimide (NTCDI), form complexes formula [(NTCDI)2(PAH)@1]4+. For these host:guest adducts, ESI IM-MS studies revealed that 47–49 Å2.. energy-minimized structures [1]4+, [C60@1]4+, [C70@1]4+, [(NTCDI)2(corannulene)@1]4+ in gas phase obtained DFT calculations.Introduction

for more complex analysers for automated sample processing and plant control. The separation time will continue to decrease; in the past there has been limited interest in fast separations but this could change as automated sample processing is developed. Increasing use of coupled techniques such as GC-GC, liquid chromatography-GC, and supercritical Suid chromatography-GC for the separation of ...

"Why are we interested in ion mobility?" Ion mobility is not a new technique, but its recent marriage with high-resolution mass spectrometry on a commercial platform has made it possible to combine its separation and characterization capabilities with the power of MS and MS/MS data – the determination of size and shape as well as mass and charge. We are now seeing a rapid growth of applications...
