a Normalized electroluminescence spectra from devices incorporating 1 in host-free and host-guest structures. b CIE colour space chart depicting the apparent colour of electroluminescence from OLED devices incorporating CMA emitters in host-free and host-guest structures. CIE coordinates for 3 in TCP host and host-free structures are reproduced from ref. 19.
