Several organic molecules will be intercalated into the interlayer of a clay mimic constructed of 3,5-pyridinedicarboxylic acid and a diamine. The two diamines used are 1,10 diaminodecane and 1,12 diaminododecane. The clay mimic crystals were sonicated in a solution of the individual organic molecules, most of which contain polar groups, and tests were taken of the sonicates to determine if intercalation occurred. The three tests used were differential scanning calorimeter (DSC), thermogravimetric analysis (TGA), and NMR. Results for several guest molecules will be discussed, including results for different polar organic molecules. Synthesis of an amine-containing ether to replace the diamines used will also be discussed. The presence of oxygen atoms in the carbon chain will hopefully provide more possible hydrogen bonding sites to secure the intercalated guests.
