Selectivity of Picoline\nby Enclathration: Structure\nand Kinetics of Decomposition

The host 9,10-[2-(9-hydroxy-9-fluorenyl)ethynyl] anthracene\nforms\ninclusion compounds with guests of pyridine and each of the picoline\nisomers. Pairwise competition with equimolar guests yielded crystals\nfrom both mother liquor and gels. The selectivity sequence resulted\nin the preference 4PIC > 3PIC > 2PIC > PYR. The kinetics\nof the desorption\nwas analyzed by thermogravimetric analysis at variable temperatures\nand yielded activation energies varying from 13.2 to 16.7 k J mol<sup>–1</sup>.

Abstract

The host 9,10-[2-(9-hydroxy-9-fluorenyl)ethynyl] anthracene\nforms\ninclusion compounds with guests of pyridine and each of the picoline\nisomers. Pairwise competition with equimolar guests yielded crystals\nfrom both mother liquor and gels. The selectivity sequence resulted\nin the preference 4PIC > 3PIC > 2PIC > PYR. The kinetics\nof the desorption\nwas analyzed by thermogravimetric analysis at variable temperatures\nand yielded activation energies varying from 13.2 to 16.7 k J mol<sup>–1</sup>.
