An efficient strategy for the controllable synthesis of BODIPY arrays based on the Stillecross-couplingreaction has been developed, from which a family of well-defined ethene-bridged BODIPY arrays from dimer to hexamer was synthesized. These arrays showed strong absorptions reaching the near-infrared II (NIR II, 1000–1700 nm) region with maxima tunable from 702 nm (dimer) to 1114 nm (hexamer) and
