Control yourself! A two‐color molecular beacon with non‐nucleosidic chromophores in a triplex stem is presented. Pyrene and PDI fluorophores act as mutual quenchers by formation of a donor–acceptor complex in the closed form. Hybridization with the target results in two independent fluorescence signals. The two‐color read‐out provides a “self‐control” feature, which helps to eliminate false positive signals in imaging and screening applications.
