“…Further, we utilize these phosphor‐LP hybrids as efficient light‐harvesting scaffolds by the orthogonal functionalization of the LP nanoclays with negatively charged fluorescent dyes. These multi‐component donor–acceptor hybrids show delayed fluorescence from the acceptor molecule by an efficient TS‐FRET which is seldom reported in the solution phase [8b] . Interestingly, we also show that, at higher concentration, these LP‐phosphor hybrids form self‐standing hydrogels which also shows highly efficient phosphorescence and tunable long‐lived fluorescence by the delayed sensitization of the singlets of various acceptor dyes.…”

Solution phase room‐temperature phosphorescence (RTP) from organic phosphors is seldom realized. Herein we report one of the highest quantum yield solution state RTP (ca. 41.8 %) in water, from a structurally simple phthalimide phosphor, by employing an organic–inorganic supramolecular scaffolding strategy. We further use these supramolecular hybrid phosphors as a light‐harvesting scaffold to achieve delayed fluorescence from orthogonally anchored Sulforhodamine acceptor dyes via an efficient triplet to singlet Förster resonance energy transfer (TS‐FRET), which is rarely achieved in solution. Electrostatic cross‐linking of the inorganic scaffold at higher concentrations further facilitates the formation of self‐standing hydrogels with efficient RTP and energy‐transfer mediated long‐lived fluorescence.

“…According to our previous studies on bromophenylpyridinium derivatives, it is speculated that the two bromophenylpyridinium parts may be wrapped into the cavity of CB[8] in a head to tail orientation. 66 In the 2D DOSY spectra (Fig. S20, ESI‡), the self-diffusion coefficient of BPA decreases from 1.255 × 10 −10 to 7.896 × 10 −11 m 2 s −1 after adding CB[8] , indicating the formation of a large assembly.…”

The design and characterization of purely organic room‐temperature phosphorescent (RTP) materials for optoelectronic applications is currently the focus of research in the field of organic electronics. Particularly, with the merits of preparation controllability and modulation flexibility, host–guest material systems are encouraging candidates that can prepare high‐performance RTP materials. By regulating the interaction between host and guest molecules, it can effectively control the quantum efficiency, luminescent lifetime, and color of host–guest RTP materials, and even produce RTP emission with stimuli‐responsive features, holding tremendous potential in diverse applications such as encryption and anti‐counterfeiting, organic light‐emitting diodes, sensing, optical recording, etc. Here a roundup of rapid achievement in construction strategies, molecule systems, and diversity of applications of host–guest material systems is outlined. Intrinsic correlations between the molecular properties and a survey of recent significant advances in the development of host–guest RTP materials divided into three systems including rigid matrix, exciplex, and sensitization are presented. Providing an insightful understanding of host–guest RTP materials and offering a promising platform for high throughput screening of RTP systems with inherent advantages of simple material preparation, low‐cost, versatile resource, and controllably modulated properties for a wide range of applications is intended.
