Abstract: Abstract Organic molecules with persistent room-temperature phosphorescence (RTP) have attracted considerable attention due to their broad applications, but typically suffered from low emission intensity and short lifetime. In this contribution, a twisted donor-acceptor (D-A) system… read more here.

DOI: 10.1038/s41467-020-14669-3
Abstract: Developing high-efficient afterglow from metal-free organic molecules remains a formidable challenge due to the intrinsically spin-forbidden phosphorescence emission nature of organic afterglow, and only a few examples exhibit afterglow efficiency over 10%. Here, we demonstrate… read more here.

DOI: 10.1038/s41467-022-28070-9
Abstract: Circularly polarized organic afterglow (CPOA) with both long-lived room-temperature phosphorescence (RTP) and circularly polarized luminescence (CPL) is currently attracting great interest, but the development of multicolor-tunable CPOA in a single-component material remains a formidable challenge.… read more here.
