From 1974 until retirement in 2009, my research examined metal complexes having coordination spheres dominated by thioether donors. We explored these species primarily by esr, nmr, electronic spectroscopic, electrochemical and magnetic susceptibility measurements in both the solution and solid states as well as by X-ray diffraction. The reason behind this research was as follows. By the latter half of the twentieth century, mankind's ability to design and synthesize specific molecules was highly advanced, but the ability to design bulk samples of matter having predetermined properties that are themselves controlled by interactions between molecules was less perfect. Certain attributes of bulk samples of matter such as magnetic, optical, energy capture and conversion properties are commercially prized even though they cannot at the time of writing be designed as easily as a molecular structure. Thus, the long term goal of research in my laboratory was to extend mankindís existing expertise in molecular design to the preparation of bulk samples of matter that would display specific and commercially viable chemical, photo, magnetic, optical or electrical properties.
Since retirement, my research has been guided by a desire to promote the careers of former students, post-doctoral fellows and younger professional associates. Thus, it has tended to follow a course dictated as much by their professional interests as my own. There are, nonetheless, threads of transition metal compound synthesis, magnetostructural correlation, catalysis and structure/property correlation that continue to run through this body of work as they did prior to retirement.
