“…With the idea of clusteroluminescence, it is possible to produce multicolor emission from such nonconjugated compounds based on their different through-space interaction (TSI) properties in the clustered state, which could eventually achieve whitelight emission. [88][89][90][91] Zhang et al synthesized a linear siloxanebased poly(hydroxyurethane) (PHU) that contained carbonyl, hydroxyl groups, and ether bonds [Fig. 5(a)].…”

White light, which contains polychromic visible components, affects the rhythm of organisms and has the potential for advanced applications of lighting, display, and communication. Compared with traditional incandescent bulbs and inorganic diodes, pure organic materials are superior in terms of better compatibility, flexibility, structural diversity, and environmental friendliness. In the past few years, polychromic emission has been obtained based on organic aggregates, which provides a platform to achieve white-light emission. Several white-light emitters are sporadically reported, but the underlying mechanistic picture is still not fully established. Based on these considerations, we will focus on the single-component and multicomponent strategies to achieve efficient white-light emission from pure organic aggregates. Thereinto, single-component strategy is introduced from four parts: dual fluorescence, fluorescence and phosphorescence, dual phosphorescence with anti-Kasha's behavior, and clusteroluminescence. Meanwhile, doping, supramolecular assembly, and cocrystallization are summarized as strategies for multicomponent systems. Beyond the construction strategies of white-light emitters, their advanced representative applications, such as organic light-emitting diodes, white luminescent dyes, circularly polarized luminescence, and encryption, are also prospected. It is expected that this review will draw a comprehensive picture of white-light emission from organic aggregates as well as their emerging applications.

“…However, these RTP materials often face challenges related to low RTP emission efficiency due to their weak spin–orbit coupling (SOC) and the forbidden nature of triplet transitions [ 13 , 14 ]. To enhance the performance of purely organic RTP materials, two key strategies have emerged: promoting the intersystem crossing (ISC) process by enhancing SOC and suppressing non-radiative pathways by restricting molecular motions [ 15 , 16 , 17 , 18 ]. Most purely organic RTP materials exhibit good RTP properties under ‘static’ conditions but rarely do so under ‘dynamic’ conditions.…”

Developing materials with dynamic room-temperature phosphorescence (RTP) properties is crucial for expanding the applications of organic light-emitting materials. In this study, we designed and synthesized two novel RTP molecules by combining functional units, incorporating the folded unit thianthrene into the classic luminescent cores thioxanthone or anthraquinone to construct TASO and TA2O. In this combination, the TA unit contributes to the enhancement of spin–orbit coupling (SOC), while the luminescent core governs the triplet energy level. After the strategic manipulation of SOC using the thianthrene unit, the target molecules exhibited a remarkable enhancement in RTP performance. This strategy led to the successful development of TASO and TA2O molecules with outstanding dynamic RTP properties when exposed to continuous ultraviolet irradiation, a result that can be ascribed to their efficient RTP, improved absorption ability, and oxygen-sensitive RTP properties. Leveraging the oxygen-mediated ultraviolet-radiation-induced RTP enhancement in TASO-doped polymer films, we developed a novel time-resolved detection technique for identifying phase separation in polymers with varying oxygen permeability. This research offers a promising approach for constructing materials with dynamic RTP properties.
