Abstract High‐performance film‐based sensors are key innovations driving advancements in sensing technologies. An ultra‐sensitive formic acid sensor based on a polymer fluorescent nanofilm synthesized via interfacial assembly using tetraphenylethylene derivative functionalized with aldehyde and hydroxyl groups is reported. These promote imine bond formation enhance selectivity. The nanofilm, prepared through dynamic condensation 4,4′‐diaminodiphenyl ether at the air‐DMSO interface, exhibits excellent luminescence, flexibility, tunable surface topography. Its bright fluorescence primarily due to aggregation‐induced emission (AIE) property hydrogen bonding interactions within film structure. Imines serve as recognition sites for acid, where weak alters electronic environment of groups, blocking proton donors (─OH) promoting non‐radiative decay, leading selective quenching. achieves an ultra‐low detection limit 550 ppt, rapid response time 0.3 s, reversibility. It also demonstrates high selectivity over other VOCs, making it suitable real‐time monitoring. Additionally, nanofilm's multimodal capabilities, including responses HCl NH 3 , highlight its potential diverse environmental industrial applications.
