Fig. 2. A crystalline capsule of 1o encapsulating fluorescent dye solution. (a) A 1o crystal encapsulating 5(6)-FAM solution and the crystal irradiated with 450 nm light, which does not induce the photoreaction of 1o. Green fluorescence was observed from 5(6)-FAM solution. (b) Crystal irradiated with 365 nm light, which induces the photoreaction of 1o to release the solution by a photosalient phenomenon. The fluorescence area from 5(6)-FAM expanded on the water surface over time (ESI Movie S5†).
