Exploring anagostic interactions in 5,15-porphodimethene metal complexes.

Using a metal templating strategy, 5,15-porphodimethene metal complexes were synthesized and their structure confirmed by single crystal X-ray analysis. The anagostic interaction causes distortion, while the hydrogen bonding interactions generate dimerisation and array formation in these complexes.

Fluorine interaction controlled AIEE phenomenon in an expanded calixbenzophyrin and its vapoluminescent response: turn on emission with volatile ketones and esters.

Fluorine interaction assisted AIEE characteristic in an expanded calixbenzophyrin is presented by single-crystal X-ray-diffraction analysis and molecular modelling approaches. Selective exposure to volatile organic compounds such as ketones and esters results in the breaking of fluorine interaction, leading to enhanced monomer emission.
