Multi‐Dimensional Color Tunable Long Persistent Luminescence in Metal Halide‐Based CPs Through Precise Manipulation of Electronic and Steric Effects

Regulating strategies for long persistent luminescence (LPL) are always in high demand. Herein, a series of coordination polymers (CPs) (SUST-Z1-Z4) are fabricated using 1,10-phenanthroline derivatives involving different substituents (─H, ─CH
