Triplet-triplet annihilation-based molecular photon upconversion (TTA-UC) is a photophysical phenomenon that can yield high-energy emitting photons from low-energy incident light. TTA-UC believed to fuse two triplet excitons into singlet exciton through several consecutive energy-conversion processes. When organic aromatic dyes─i.e., sensitizers and annihilators─are used in TTA-UC, intermolecular distances, as well relative orientations between the chromophores, are important an attempt...

The precise recognition and sensing of steroids, a type vital biomolecules, hold immense practical value across various domains. In this study, we introduced corral[4]BINOLs (C[4]BINOLs), pair enantiomeric conjugated deep-cavity hosts, as novel synthetic receptors for binding steroids. Due to the strong hydrophobic effect their deep nonpolar, chiral cavities, two enantiomers C[4]BINOLs demonstrated exceptionally high affinities (up 10
