Normalised emission kinetics in 5% PMMA films of a, TTM-1Cz-An,b, TTM-1Cz-PhAn, and c, (TTM-1Cz)2-An. All materials show temperature-activated delayed emission. d, Time gated emission spectra in 5% TTM-1Cz-An in PMMA films at 10 K, and e, 300 K. All measurements performed in vacuum after excitation at 520 nm with fluence of 26 μJ cm−2 (for R-A) or 530 nm with fluence of 8.7 μJ cm−2 (for R-A-R).
