Abstract

Sustainable organic afterglow room-temperature phosphorescence (RTP) is a particularly attractive phenomenon but remains difficult to achieve. Herein, inspired by the afterglow RTP of natural basswood, we prepare a series of sustainable afterglow RTP materials by confining lignin within a 3D poly(acrylic acid) network that mimics the wood matrix. The RTP emission of these materials could be finely tuned either by varying the drying temperature or the crosslinking density. Afterglow RTP emission could also be produced by embedding different types of lignin in a variety of 3D polymeric networks, thus demonstrating the generality of our strategy for preparing sustainable lignin-based RTP materials. As an illustration of potential applications, the lignin-based RTP materials are used to coat cotton fibers, which are then incorporated into luminescent textiles.
