“…Room-temperature phosphorescence (RTP) materials play a pivotal role in bioimaging, anticounterfeiting, information encryption, optical displays, and chemical detection. − At present, most RTP materials are precious metals, rare element–containing inorganic materials, or organic–inorganic complexes and are associated with high costs, high toxicity, low processability, and difficult fabrication processes, hindering their practical applications. − In recent years, several studies have reported that certain natural products, such as cellulose, maltose, agarose, and sodium alginate, without a well-defined chromophore or conjugated structure exhibit fluorescence or/and RTP in concentrated solution or solid-state conditions. These molecules usually contain heteroatom groups (groups containing, e.g., N, O, and S) and exhibit concentration-dependent fluorescence and excitation-dependent emission.…”

Room-temperature phosphorescence (RTP) materials with high mechanical strength are attractive and important but rarely reported. In this study, konjac glucomannan (KGM), a polysaccharide derived from natural taro, was observed to emit long-lived RTP via clusterization-triggered emission (CTE). The CTE behavior of KGM was fully investigated in solution and in the solid state. The distinct concentration-enhanced emission observed for KGM aqueous solutions, combined with its low toxicity and high biocompatibility, renders KGM highly promising for bioimaging. KGM foams were observed to emit RTP via the fixation of multiple hydrogen bonds to clusters of oxygen-containing groups. The phosphorescence lifetime of KGM foam could reach 351.2 ms, and the lightweight KGM foam could withstand compressive stress of 5.73 MPa. KGM foams exhibit typical excitation wavelength (λ ex )-dependent color-tunable RTP, with afterglows changing from blue-green to grass-green as λ ex is increased from 310 to 365 nm. The results indicate that KGM is suitable for the development of eco-friendly RTP materials with high mechanical strength.

Nonconventional luminophores have received increasing attention, owing to their fundamental importance, advantages in outstanding biocompatibility, easy preparation, environmental friendliness and potential applications in sensing, imaging and encryption, etc. Purely organic molecules with outstanding fluorescence and room‐temperature phosphorescence (RTP) have emerged as a new library of benign afterglow agents. However, the cost, toxicity, high reactivity and poor stability of materials also limit their practical applications. Therefore, some natural products, synthetic compounds and biomolecules have entered horizons of people. The as‐designed exhibits sky blue and green fluorescence emission and green RTP emission (a lifetime of 343 ms and phosphorescence quantum of 15.3%) under air condition. This study presents an organic fluorescence for biological imaging and RTP for anti‐counterfeiting and encryption based on amino acids, maleic anhydride (MAH) and 4‐Vinylbenzenesulfonic acid sodium salt hydrate (SSS). This study provides a strategy for nonconventional luminophores in designing and synthesizing pure organic RTP materials.This article is protected by copyright. All rights reserved
