This was achieved by the unprecedented combination of photoactive zinc oxide NCs (ZnO NCs) with host\u2011guest chemistry of cucurbit[8]uril (CB[8]) providing a route to semiconductor-assisted light\u2011modulation of supramolecular assemblies (SALSA), here mediated by photo\u2011generation of viologen radical cations (MV+\u2022) at the NC corona and their further dimerization enhanced by CB[8] macrocycles. The reported SALSA strategy was successfully applied for light\u2011controlled reversible assembly processes at NCs interfaces enabling light\u2011triggered release of guest molecules from surface confined discrete CB[8] host\u2011guest complexes.<\/p>\n<p><img decoding=\"async\" src=\"wp-content\/uploads\/2017\/10\/nanoscale2017cb.jpg\" width=\"650px\"><\/p>\n<p>We acknowledge the National Science Centre, Poland for the support within the Preludium 2015\/17\/N\/ST5\/03333 (A.
