metal organic coordination networks of oligopyridines and Cu on graphite

Achim Breitruck, Harry E. Hoster, R. Jürgen Behm

 

 

molecule: oligopyridine 2,4’-BTP (Ziener et al.)

concept:

metal-ligand bond between pyridyl group and Cu atom stronger than hydrogen bonds between molecules

 re-organization of adlayer favorable

* new structures vary with coverage of 2,4’-BTP and Cu

 

start: Quasi quadratic network + vapor dep. Cu    

translational domain boundaries stabilized by Cu

 

 

 

 

20x20 nm2

 

 

20x20 nm2

 

 

at higher Cu content: formation of hexagonal network with Cu2 centers

structure model

 

*   new structure stabilized by metal ligand interaction in cooperation with hydrogen bonds
