摘要：Research on metal-free room-temperature phosphorescent (RTP) materials has been a hot topic and made great advances in recent years. However, developing amorphous metal-free RTP compounds whose RTP emission is insensitive to water and oxygen to expand their applications still remains a challenge. Two novel metal-free RTP compounds were facilely designed and synthesized by modifying ureidopyrinidinone (UPy) units on both ends of the phosphors (BrNpA and BrBA). On the basis of their water/oxygen insensitive phosphorescence at different emission wavelengths, pure white-light (CIE coordinates (0.32, 0.33)) emission was obtained by mixing these two compounds. Moreover, visualization of latent fingerprints employing RTP materials as the first application in forensic science, as well as protected quick response codes, was achieved by theses hydrophobic materials.
