Tuning the moisture and thermal stability of metal-organic frameworks through incorporation of pendant hydrophobic groups

An isostructural series of NbO-type porous metal-organic frameworks (MOFs) with different dialkoxy-substituents of formula Cu2(TPTC-OR) (TPTC-OR = 2′,5′-di{alkyl}oxy-[1,1′:4′,1″-terphenyl]-3, 3″,5,5″-tetracarboxylate, R = Me, Et, nPr, nHex) has been synthesized and characterized. The moisture stability of the materials has been evaluated, and a new superhydrophobic porous MOF has been identified. The relationship between pendant side chain length and thermal stability has been analyzed by in situ synchrotron powder X-ray diffraction, showing decreased thermal stability as the side chain length is increased, contradictory to thermogravimetric decomposition studies. Additionally, the four materials exhibit moderate Brunauer-Emmett-Teller (BET) and Langmuir surface areas (1127-1396 m2 g-1 and 1414-1658 m2 g -1) and H2 capacity up to 1.9 wt % at 77 K and 1 bar.

Preparation and nonlinear optics of monodisperse oligo(1,4-phenyleneethynylene)s

Oligo(1,4-phenyleneethynylene)s 1a-e, with solubilizing propoxy side chains, were prepared by use of Hagihara-Sonogashira coupling reactions. The synthetic strategy was based on a building block system and on the use of trimethylsilyl and triisopropylsily
