Synthesis of Homoditopic Ligands with an Incrementable Rodlike Backbone

We describe the synthesis of architectures that consist of a symmetrical rodlike oligo(phenylene-ethynylene) (OPE) backbone of incrementable length connected to a pair of classical ligands for metal coordination. OPE spacers decorated with various end gro

A Bis-Manganese(II)–DOTA Complex for Pulsed Dipolar Spectroscopy

High-spin gadolinium(III) and manganese(II) complexes have emerged as alternatives to standard nitroxide radical spin labels for measuring nanometric distances by using pulsed electron–electron double resonance (PELDOR or DEER) at high fields/frequencies.

Porous interpenetrated zirconium-organic frameworks (PIZOFs): A chemically versatile family of metal-organic frameworks

We present the synthesis and characterization of porous interpenetrated zirconium-organic frameworks (PIZOFs), a new family of metal-organic frameworks obtained from ZrCl4 and the rodlike dicarboxylic acids HO 2C[PE-P(R1,R2)-EP]CO2H that consist of alternating phenylene (P) and ethynylene (E) units. The substituents R 1,R2 were broadly varied (alkyl, Oalkyl, oligo(ethylene glycol)), including postsynthetically addressable substituents (amino, alkyne, furan). The PIZOF structure is highly tolerant towards the variation of R 1 and R2. This together with the modular synthesis of the diacids offers a facile tuning of the chemical environment within the pores. The PIZOF structure was solved from single-crystal X-ray diffraction analysis. The PIZOFs are stable under ambient conditions. PIZOF-2, the PIZOF prepared from HO2C[PE-P(OMe,OMe)-EP]CO2H, served as a prototype to determine thermal stability and porosity. It is stable up to 325°C in air as determined by using thermogravimetry and powder X-ray diffraction. Argon sorption isotherms on PIZOF-2 revealed a Brunauer-Emmett-Teller (BET) surface area of 1250 m2 g-1 and a total pore volume of 0.68 cm3 g-1. Copyright
