Evaluation of how well the academic objectives of the proposal were met
The goal of this proposal was to train graduate and undergraduate students through research experiences in supramolecular chemistry in a multi-group environment. Academically, our objective was to synthesize and characterize new supramolecular host molecules and to develop applications for these molecules. We believe we have been quite successful, as demonstrated by the presentations and publications listed below and as shown by the receipt of a National Science Foundation grant by one of the teams involved in this research, in a year when such grants were particularly difficult to obtain.
Evaluation of the mentoring environment
The mixed undergraduate/graduate student environment of our program has worked very well. Typically, new undergraduate or graduate students initially worked with a more experienced student until they developed the skills and confidence needed to work on their own. Graduate students provided the longer-term continuity essential to success, while undergraduate students added essential manpower and enthusiasm and helped keep the personnel at “critical mass.” The whole effort was overseen by three faculty members who coordinated the work, gave direction to the research, and sought outside funding. Weekly group meetings and monthly joint meetings of all three groups gave the students opportunities to present and discuss their work in a friendly environment and to receive guidance from all the group members.

Description of the results/findings of the project
Several new resorcinarene-based supramolecular host molecules were synthesized, characterized, and applied to chromatographic columns where they were used for chemical separations. A new method for measuring molecular sizes (collision cross sections) in a Fourier transform mass spectrometer was developed and characterized, and a new method for measuring low pressures (needed for the cross section measurements) was also invented.
Description of how the budget was spent
The budget was spent primarily for student wages, with small amounts used to purchase chemical reagents, solvents, and other supplies.
