We study single dibenzoterrylene molecules in an anthracene single crystal at 1.4 K in two insertion sites at 785.1 and 794.3 nm. The single‐molecule zero‐phonon lines are narrow (about 30 MHz), intense (the detected fluorescence rates at saturation reach 100,000 counts s −1 ), and very photostable. The intersystem‐crossing yield is extremely low (10 −7 or lower). All of these features are hallmarks of an excellent system for high‐resolution spectroscopy and nanoscale probing at cryogenic temperatures.
