PMID: 26060847
Chem Commun (Camb). 2015 Jul 11;51(54):10917-20. doi: 10.1039/c5cc03255e.

We demonstrate the effective confinement of surface electrons in the pores of molecular networks formed by dehydrobenzo[12]annulene (DBA) molecules with butoxy groups (DBA-OC4) on Au(111). Investigation of the network formation starting from single molecules reveals a considerable interaction of...

A dominant theme within the research on two-dimensional chirality is the sergeant-soldiers principle, wherein a small fraction of chiral molecules (sergeants) is used to skew the handedness of achiral molecules (soldiers) to generate a homochiral surface. Here, we have...

Chemistry. 2015 Jun 01;21(23):8426-34. doi: 10.1002/chem.201406602. Epub 2015 Apr 13.

A series of novel toroidal cyclo-2,9-tris-1,10-phenanthroline macrocycles with an unusual hexaaza cavity are reported. Nickel-mediated Yamamoto aryl-aryl coupling was found to be a versatile tool for the cyclotrimerization of functionalized 1,10-phenathroline precursors. Due to the now improved processability, both...

Self-assembled air-stable supramolecular porous networks on graphene.

To demonstrate key roles of multiple interactions between multiple components and multiple phases in the formation of an uncommon self-assembling pattern, we present here the construction of a porous hexagonal star (h-star) structure using a trigonal molecular building block...

Self-assembly of a TTF derivative capable of forming self-assembled monolayers at the surface of graphite displays hierarchical growth of multilayers and concentric nanorings upon evaporation of the solvent as observed by AFM.

Anti-restenosis Trials.

Current interventional cardiology reports

de Feyter PJ, Vos J, Rensing BJ.
PMID: 11096683
Curr Interv Cardiol Rep. 2000 Nov;2(4):326-331.

The high frequency of restenosis after percutaneous coronary angioplasty is still a major clinical problem. It occurs in 30% to 60% of patients and limits the long-term success of angioplasty. Many clinical trials have been conducted to resolve this...
