Most species prepared using water as a reactant are nonaromatic and nonconjugated, serving as commodities for everyday use. For example, chloroplasts can convert H 2O and carbon dioxide into carbohydrates and oxygen through photosynthesis, which is one of nature’s most critical H 2O-involved reactions. Nature uses H 2O as a feedstock to synthesize various complex species continuously. Water (H 2O), occupying 71% of our earth’s surface area, is life’s origin. Thus, this work develops a method to synthesize clusteroluminogens using water, builds a clear structure-property relationship of clusteroluminogens, and provides a strategy to in situ construct functional water-based polymeric films.

It exhibits a vapor-triggered reversible mechanical response which could be applied as a smart actuator. The synthesized polymeric film is also verified as a Janus film. The interfacial polymerization-enhanced emission of the polymeric films is observed, where the emission red-shifts and efficiency increases when the polymerization time is prolonged. Besides, the free-standing polymeric films with much high photoluminescence quantum yields (up to 45.7%) are in situ generated via a water-involved interfacial polymerization. Their emission colors and luminescent efficiency could be adjusted by manipulating through-space interaction using different starting materials. The synthesized products are proven as nonaromatic clusteroluminogens that could emit visible light. Herein, a chemistry of water and alkyne is developed. Exploring approaches to utilize abundant water to synthesize functional molecules and polymers with efficient clusteroluminescence properties is highly significant but has yet to be reported.
