Fig. 4. (a) Steady state emission of BCzBN doped in the LC8 series (1 wt%), neat emission of LC8 (black dashed trace) and absorption of BCzBN in methylcyclohexane (MCH, c = 0.02 mM) given for comparison (black trace); (b) temperature dependent lifetime measurements of LC8 doped with BCzBN, inset shows the corresponding steady state emission; (c) emission pathway of LC8 doped with BCzBN; (d) steady state emission of BCzBN doped in the LCn series (c = 1 wt%, blue traces), neat emission of the respective LCn derivative given for comparison (black dashed traces). Conditions for films: spin-coated from CHCl3, c = 1 wt%, steady state: λexc = 350 nm, time resolved: λexc = 379 nm.
