Altering the manner in which groups are connected could offer a straightforward approach to achieving different functionality. Herein, heterotetraarylene molecules with varying bond‐linked quinoline moieties synthesized and designed investigate their differential performances. The carbon‐carbon double bonded quinolines exhibits multifunctional properties: 1) all‐visible light‐induced photochromism, 2) acidochromism, 3) acid–base gated photoswitch. Simultaneously, it achieves dual‐mode fluorescence modulation through both photoexcitation acid/base stimuli. However, by carbon single bonds exhibit divergent properties, including emission enhancement solvent‐dependent emission. This bond‐selective functional divergence enables precise customization of stimulus‐responsive simple connectivity control, establishing novel design paradigm for smart molecular systems. Furthermore, heterotetraarylene‐linked many thus allowing construction new dual‐responsive encryption system.
