ν-DABNA-M (a, b) and ν-DABNA-M-B-Mes (c, d) in poly(methyl methacrylate) (PMMA; 1 wt% doped films). a, c Steady-state PL (fluorescence) spectra at 300 K (blue) and 77 K (red) without delay time and phosphorescence spectra at 77 K (green) with a delay time of 25 ms. b, d Transient photoluminescence decay curves at 300 K and their relevant parameters. The red curves represent the single exponential fitting data (background =1).
