The synthesis and fluorescence properties of novel bis(salicylaldiminato)zinc( II ) Schiff‐base complexes is reported. Selfassembled monolayers (SAMs) of these complexes are obtained by reaction of coupling layers, functionalized quartz substrates and a derivatized precursor complex. A comparison between the integrated emission intensity of the SAM films and that of a suitable model compound in solution indicates molecular fluorescence retention of the Zn II Schiff bases on going from the solution phase to the monolayer. This is consistent with the absence of significant self‐quenching processes, as expected on the basis of the relatively high estimated surface coverage. (© Wiley‐VCH Verlag GmbH & Co.
