In article number 2001078, Toshinori Matsushima, Atula S. D. Sandanayaka, Chihaya Adachi, and co‐workers synthesize an organic laser dye, DCNP. Photophysical studies suggest that the triplets formed on the DCNP emitter are easily transferred to BSBCz host molecules, whose triplet absorption does not seriously overlap with the device emission spectrum, thereby completely eliminating triplet‐induced losses.
