The main objective of confining fullerene molecules is to utilize their physico-chemical properties in commonly used media in which they are insoluble. Herein, a fluorenone-based large trigonal Pd₆ molecular barrel (M1) was synthesized by coordination self-assembly to act as a potential fullerene trap. M1, in the presence of fullerene C₇₀, converted to a larger Pd₈ tetrafacial barrel (M2) forming stable host-guest adduct, (C₇₀)₃@M2. The PF₆ ^- analogues of both M1 and (C₇₀)₃@M2 were acetonitrile soluble, generated reactive oxygen species due to the presence of photosensitizing fluorenone moieties in their bChemical science12885-12895https://www.ebi.ac.uk/biostudies/studies/S-EPMC12164367biostudies-literatureTransformation of a Pd<sub>6</sub> trifacial barrel to a Pd<sub>8</sub> tetrafacial barrel by C<sub>70</sub> as guest and oxidative photolysis of alkenes using the C<sub>70</sub> encapsulated barrel under red light.PMC12164367Banerjee RAdhikari DAggarwal MMaji SMukherjee PSRoy MfalseTransformation of a Pd<sub>6</sub> trifacial barrel to a Pd<sub>8</sub> tetrafacial barrel by C<sub>70</sub> as guest and oxidative photolysis of alkenes using the C<sub>70</sub> encapsulated barrel under red light.Fabricating discrete molecular cages as fullerene receptors has been a compelling task.
