A set of (Ln[14-MC-5])LnZn(quinHA)(ph)(Hph)(OH)(HO) metallacrowns (, Ln = Tb, Gd, or Yb; HquinHA = quinaldic hydroxamic acid, Hph = phthalic acid) have been synthesized via solution-state self-assembly. The metallacrowns possess an uncommon topology within the metallacrown family where two rarely seen 14-metallacrown-5 moieties are fused by a YbZn(quinHA) bridge. Moreover, analyzed in the solid state exhibits a characteristic near-infrared luminescence signal arising from Yb F→F transition despite the proximity of high energy O-H oscillators.

Persistent luminescence describes the phenomenon whereby luminescence remains after the stoppage of excitation. Recently, upconversion persistent luminescence (UCPL) phosphors that can be directly charged by near-infrared (NIR) light have gained considerable attention due to their promising applications ranging from photonics to biomedicine. However, current lanthanide-based UCPL phosphors show small absorption cross sections and low upconversion charging efficiency.

Compared with the ripple of visible Eu-based emission intensity induced by appended [FeN] spin crossover (SCO) units, as detected in the triple-stranded [EuFe()] helicate, the lanthanide-based luminescent detection of Fe spin-state equilibria could be improved significantly if the luminophore emission is shifted toward the near-infrared (NIR) domain. Replacing Eu with Nd in [NdFe()] (i) maintains the favorable SCO properties in acetonitrile [critical temperature = 322(2) K], (ii) saturates nonradiative vibrational relaxation processes in the 233-333 K range, and (iii) boosts the crucial intramolecular Nd → Fe energy transfer rate processes, which are sensitive to the spin state of the Fe metallic center. Consequently, the steady-state NIR Nd(F → I) emission of the luminophore is amplified and linearly correlated with the low-spin-[FeN] and high-spin-[FeN] mole fractions controlled by the SCO equilibrium.

Lanthanide(iii) (Ln) complexes have desirable photophysical properties for optical bioimaging. However, despite their advantages over organic dyes, their use for microscopy imaging is limited by the high-energy UV excitation they require and their poor ability to cross the cell membrane and reach the cytosol. Here we describe a novel family of lanthanide-based luminescent probes, termed dTAT[Ln·L], based on (i) a DOTA-like chelator with a picolinate moiety, (ii) a two-photon absorbing antenna to shift the excitation to the near infrared and (ii) a dimeric TAT cell-penetrating peptide for cytosolic delivery.

This study innovatively addresses challenges in enhancing upconversion efficiency in lanthanide-based nanoparticles (UCNPs) by exploiting Shewanella oneidensis MR-1, a microorganism capable of extracellular electron transfer. Electroactive membranes, rich in c-type cytochromes, are extracted from bacteria and integrated into membrane-integrated liposomes (MILs), encapsulating core-shelled UCNPs with an optically inactive shell, forming UCNP@MIL constructs. The electroactive membrane, tailored to donate electrons through the inert shell, independently boosts upconversion emission under near-infrared excitation (980 or 1550 nm), bypassing ligand-sensitized UCNPs.
