Abstract
Organic room temperature phosphorescence (RTP) materials have attracted increasing attention for their advantages such as easy preparation, low toxicity, and low cost. These materials show favorable performance in the fields of bioimaging, solid-state lighting, and anti-counterfeiting. In this paper, a novel RTP material was prepared using modified montmorillonite as host and 4,4′-biphenyldiboronic acid as guest. Under the 290 nm excitation, materials exhibit intense room-temperature phosphorescence centered at around 500 nm with a phosphorescence lifetime of 268 ± 2 ms. The modified MT developed in this work can largely eliminate the phosphorescence quenching effect of FeIII. Additionally, it provides a more stable and rigid environment for organic molecules, thus suppressing non-radiative transitions and realizing phosphorescence emission. The preparation process of this work has the advantages of low cost and easy operation, providing a new approach for the development of organic RTP materials with a promising application prospect.
