Cover Picture (Angew. Chem. Int. Ed. 17/1999)
The cover picture shows in the top left corner a combinatorial library of colored metal–organic complexes of N,O ligands in an aluminum block used for library synthesis and screening of novel polymerization catalysts. The bottom right corner contains an IR thermographic image of a library of olefin polymerization catalysts in a typical 8 × 12 format on a microtiter plate under screening conditions. The illuminated spots indicate catalytically active compositions. The background shows a microtiter plate in the typical 8 × 12 format. The central picture displays a 17 × 17 library of transition metal oxides on a 7.62-cm silicon wafer for the combinatorial study of novel luminescent materials. The luminescent library was generated with custom-designed software and then deposited by physical vapor deposition (PVD) onto the silicon wafer using a masking technique and pulsed laser technology. Jandeleit, Schaeffer et al. present more on this theme on pages 2494–2532. The cover picture was adapted by E. Turner from Eye For Design. © 1999 Symyx Technologies, Inc.
