Deployment into diverse applications involves different requirements such as specific UV emission ranges, elimination of metal sensitizer complexes to promote biocompatibility, or reduced costs for scalable production. Towards this end, we find an enormous flexibility to "mix and match" sensitizers and annihilators that generate UV UC emission. To assess the generalizability of the encapsulation method, five sensitizers and four annihilators -twenty distinct UC pairs-were integrated into micelles (Fig. ). In addition to the aforementioned iridium complexes, we selected two pure organic sensitizers, 3,3'-carbonylbis(7-diethylaminocoumarin) (CBDAC) and 2,4,5,6-tetra(carbazol-9-yl)benzene-1,3-dicarbonitrile (4CzIPN), to investigate the scope of materials compatible with this encapsulation method. We encapsulated annihilators with different UV emission ranges: pyrene, 1,4-bis((triisopropylsilyl)ethynyl)naphthalene (TIPS-Nph), and 2,5-Diphenyloxazole (PPO). We note that PPO emits photons at wavelengths shorter than 350 nm, which is a particularly attractive range for photochemical reactions. UC emissions from all 20 encapsulated UC systems are shown in Fig. , with each spectrum normalized to its emission at 425 nm. We found that all but one of the systems formed successful UV-emitting UC micelles. The only unsuccessful combination of CBDAC and PPO did not show UCPL in the micelle precursor TCB solution nor in toluene. Slightly red-shifted UC emissions were observed from pyrene and TIPS-Nph and are attributed to molecular aggregation. Overall, this incredible flexibility to mix-and-match sensitizers and annihilators in micelles presents opportunities to meet the diverse requirements of a wide range of applications. .
