Summary: Tuning Forster resonance energy transfer (FRET) in metal-organic frameworks (MOFs) for fluorescence turn-on sensing was investigated. Different donor/acceptor ratios were employed to design and synthesize FRET-based MOFs. By oxidizing the acceptor, the FRET process in MOFs can be efficiently modulated, resulting in controlled fluorescence turn-on of the framework. An optimized MOF with a donor/acceptor ratio of 7.0 was used as a sensitive and selective fluorescence turn-on sensor for Hg(II) ions. This study not only provides a useful method for constructing fluorescence turn-on sensors, but also stimulates the development of novel FRET-based MOFs for fluorescence turn-on sensing of target analytes in the future.

Summary: This study demonstrates the construction of a charge transfer (CT) organic material with important electrical properties, where the charge transfer state is generated via delocalization through H-bonding interaction pathway. The reaction of simple organic molecule pyromellitic acid with orthophenylene diamine gives a colorless cocrystal 1', which undergoes a rare transition to an orange charge transfer state 1 in methanol water media over several days. The charge transfer state 1 shows semiconducting and fluorescent properties, with X-ray diffraction analysis revealing the formation of a charge separated extended H-bonded network responsible for the delocalization of charge in the system. This is the first example of constructing a donor-acceptor-based charge transfer material by tuning the H-bond distance of a colorless cocrystalline state with non-chalcogen and non-halogenated molecules.

Summary: Delocalized carbon-based radical species with unpaired spin have been used to fabricate Cu-PLY- and ZnPLY-based organic magnetic tunnel junctions. These junctions show nonlinear and weakly temperature-dependent current-voltage characteristics, indicating tunneling as the dominant transport mechanism. Cu-PLY-based OMTJs exhibit significant magnetoresistance due to the formation of hybrid states at the metal-molecule interfaces called spinterface, and also show stable voltage-driven resistive switching.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
