TI  - Triplet energy migration-based photon upconversion by amphiphilic molecular 
      assemblies in aerated water.

AB  - A molecular self-assembly approach is developed to resolve an outstanding issue 
      in triplet energy migration-based photon upconversion (TEM-UC), that is, 
      air-stable TEM-UC in water. Amphiphilic cationic acceptor (emitter) molecules 
      self-assemble in water via hydrophobic and hydrogen bonding interactions, with 
      which anionic donor (sensitizer) molecules are integrated through electrostatic 
      interactions. Triplet energy is quantitatively transferred from the excited donor 
      to the acceptor, which is followed by effective triplet energy migration among 
      the pre-organized acceptors. It leads to TTA and concomitant UC emission in 
      water. The dense acceptor chromophore arrays with extended hydrogen bonding 
      networks show efficient barrier properties against molecular oxygen, as 
      demonstrated by the stable UC emission even in air-saturated water.
