high quantum yield (at least 0.64) over a widetemperaturerange (−50 to +100 °C) and changes from green to blue as the temperature is increased (see picture). The luminescence color was determined by the population of the two distinct excited‐state conformations—a local excited state (high temperature) and a twisted intramolecular charge‐transfer state (low temperature).
