An n-type semiconducting diazaporphyrin-based hydrogen-bonded organic framework.

Significant effort has been devoted to the development of materials that combine high electrical conductivity and permanent porosity. This paper discloses a diazaporphyrin-based hydrogen-bonded organic framework (HOF) with porosity and n-type semiconductivity. A 5,15-diazaporphyrin Ni(ii) complex with carboxyphenyl groups at the positions afforded a HOF due to hydrogen-bonding interactions between the carboxy groups and -nitrogen atoms.

Direct observation of dimethyl sulfide trapped by MOF proving efficient removal of sulfur impurities.

Here, we report the adsorptive removal of trace amounts of dimethyl sulfide (DMS) using metal-organic frameworks (MOFs). Cu-based MOFs with open metal sites (OMSs), [Cu(btc)] (HKUST-1), where btc = 1,3,5-benzenetricarboxylate, and without OMSs, [Cu(bdc)(dabco)] (Cu-JAST-1), where bdc = 1,4-benzenedicarboxylate and dabco = 1,4-diazabicyclo[2.2.
