TL;DR: In this paper, a pillared-paddlewheel metal-organic framework (MOF) was constructed from a tetrakis(4-carboxyphenyl)porphyrin sensitizer and a dipyridyl thiazolothiazole annihilator, designed for efficient triplet-triplet annihilation upconversion (TTA-UC).

TL;DR: The host-guest adducts display absorption bands in the visible spectral region, characteristic of charge-transfer interactions, and reversible decomplexation/recomplexation takes place upon electrochemical oxidation/reduction of the ferrocene-based unit or upon reduction/oxidation of the tetracationic cyclophane.

TL;DR: In this paper, a novel synthetic strategy for exchanging stoppers on rotaxanes, without them losing their integrity as interlocked molecules, is presented, relying upon the ability of a benzylic triphenylphosphonium function to undergo a Wittig reaction with a bulky aromatic aldehyde to form a ‘stilbenoid’ [2] rotaxane as a mixture of cis and trans isomers, without the occurrence of any dethreading of the crown ether ring component.

TL;DR: The operation of the megagates was demonstrated by time-resolved fluorescence spectroscopy which is capable of monitoring the release of both the payload and the cap and opens up new possibilities in the field of controllable release.

TL;DR: Electrochemical studies on solid-state thin films of the macrocycle show that they exhibit semiconducting properties with a redox-conductivity of up to 7.6×10-4 S m-1 and EPR and ENDOR spectroscopies show that charge is equally shared between the NDIs within the one-electron reduced state of the NDI-based macrocycle on the time scale of these techniques.
