Abstract
Porous compounds, clays and activated charcoal, have been used as adsorbents in a number of different settings such contrast for x-rays in the medical field. Unfortunately, these adsorbents are not very selective and adsorb just about everything. A new class of adsorbents known as MOF's have become of great interest because these materials are easily altered synthetically and thus offer the promise of improved control over selectivity.
Our interest has been in the derivatives of NBAII, shown below. Notice that structure A has one six membered ring in the backbone while structure B has two. When crystals of these molecules are formed porous structures result as shown in Fig. 2. The pores in crystals made from compound A have maller pores than from crystals made from B. The first two materials have been synthesized and as can be seen the size of the holes in the structure increase as the number of rings in the backbone of the parent molecule.

It was our intention to produce compound C which has three rings in its backbone for comparison with the other two. It was anticipated that even larger pores would be produced.
This poster will describe the synthetic procedures available for compound C and the progress made toward accomplishing that goal. In doing this it will prove that these molecules can be manipulated in the lab. From there research can begin for the selectivity of each of the molecule and put to practical uses.
