CH 3 NH 3 PbBr 3 perovskite nanoparticles (P AD ) are prepared with a photoluminescence quantum yield of ≈100% in air atmosphere by using the quasi‐spherical shaped 2‐adamantylammonium bromide (ADBr) as the only capping ligand. The photostability under wet conditions of this kind of nanoparticles is enhanced by using cucurbit[7]uril‐adamantylammonium (AD@CB) host–guest complexes as the capping ligand.
