Red Room Temperature Phosphorescence from Lignin

Angewandte Chemie
Abstract Materials with red room‐temperature phosphorescence (RTP) derived from sustainable resources are crucial but rarely reported. Here, we produced red RTP materials from lignin. Lignin was covalently modified with Upy (1‐(6‐isocyanatohexyl)‐3‐(6‐methyl‐4‐oxo‐1,4‐dihydropyrimidin‐2‐yl) urea) to obtain Lig‐Upy.
