摘要

Polyhedral oligomeric silsesquioxanes (POSS) have emerged as versatile building blocks for hybrid organic–inorganic materials with tailored photophysical and optoelectronic properties. Their robust cage-like core and tunable organic periphery enable integration with conjugated polymers, luminescent complexes, and nanostructured frameworks. This review critically summarizes recent advances in POSS-based systems for light-emitting devices (LEDs and OLEDs), chemical and biological sensing, and solar-energy conversion, highlighting mechanisms such as aggregation suppression, enhanced charge transport, and interfacial stabilization. Emerging applications in luminescent nanocomposites and bioimaging agents are also discussed. Finally, we outline key challenges—scalability, reproducibility, long-term stability—and identify future opportunities for POSS in next-generation optoelectronic and sustainable technologies, where multifunctionality and device-level integration will be decisive.
