Selectivity of Picoline by Enclathration: Structure and Kinetics of Decomposition
The host 9,10-[2-(9-hydroxy-9-fluorenyl)ethynyl] anthracene forms inclusion compounds with guests of pyridine and each of the picoline isomers. Pairwise competition with equimolar guests yielded crystals from both mother liquor and gels. The selectivity sequence resulted in the preference 4PIC > 3PIC > 2PIC > PYR. The kinetics of the desorption was analyzed by thermogravimetric analysis at variable temperatures and yielded activation energies varying from 13.2 to 16.7 k J mol–1.
