Intermolecular interactions in aniline–benzene hetero-trimer and aniline homo-trimer ions

Self-assembled trimer structures highlight the competitive roles of intermolecular and adsorbate-substrate interactions: PVBA trimer on Pd(111).

We observed the orientation of 4-trans-2-(pyrid-4-yl-vinyl)benzoic acid (PVBA) trimers on Pd(111) using scanning tunneling microscopy (STM) under ultrahigh vacuum (UHV). The image showed three different types of trimers, one of which does not follow predicted dimer orientations. This type of trimer displays 10° rotations of each molecule in clockwise or counterclockwise directions. Calculations...

Ab initio study of intermolecular potential of H2O trimer

Role of three-body interactions in trimer bindinga)

A semiclassical perturbation expansion is developed for the ground state energy of three identical particles interacting via pair and three-body potentials. The result is applied for the ground state energy of three neon atoms, where the non-pair-additive terms make a small contribution, and for three beryllium atoms where such terms make a large contribution. Models are constructed for the pai...

Hetero-modification of TRAIL trimer for improved drug delivery and in vivo antitumor activities

Poor pharmacokinetics and resistance within some tumor cell lines have been the major obstacles during the preclinical or clinical application of TRAIL (tumor-necrosis-factor (TNF)-related apoptosis-inducing ligand). The half-life of TRAIL114-281 (114 to 281 amino acids) was revealed to be no more than 30 minutes across species. Therefore maleimido activated PEG (polyethylene glycol) and MMAE (...
