Fast reversible energy transfer and intersystem crossing conspire to permit excited-state equilibration between three excited states in a copper(I) phenanthroline complex. Introduction of multiple quasi-isoenergetic excited states in a planned fashion represents a new strategy to prolong luminescence lifetimes of copper phenanthroline complexes (e.g., 1.2 μs compared with 70 ns for the parent complex).
