Abstract

Polymerization of 1,4-diaminonaphthalene on various Cu substrates resulting in stereoselectively well-defined metal-organic coordination polymers is reported. By using different crystallographic planes (111), (110) and (100) of a Cu substrate the structure of the resulting coordination polymer was controlled.

Highlights

Polymerization of 1,4-diaminonaphthalene on various Cu substrates resulting in stereoselectively well-defined metal–organic coordination polymers is reported
Polymerization of 1,4-diaminonaphthalene at Cu(111): evaporation of 1,4-diaminonaphthalene (DAN) at the Cu(111) substrate at room temperature leads to formation of monolayers where the organic molecules are randomly distributed showing different orientations on the surface
This means that the weakest bond in the system is much stronger than the interaction of the all oligomer with its 7Cu atoms with the substrate

Summary

Introduction

Polymerization of 1,4-diaminonaphthalene on various Cu substrates resulting in stereoselectively well-defined metal–organic coordination polymers is reported. By using different crystallographic planes (111), (110) and (100) of a Cu substrate the structure of the resulting coordination polymer was controlled. We report the effect of the substrate reconstitution on the final geometry of the coordination network and show that different crystallographic structures of the same metal (in this case Cu) control the stereochemistry of polymerization leading to coordination polymers with different relative configurations.
