Metal halide perovskite nanocrystals are emerging as novel optoelectronic materials. Owing to their excellent optical and electronic properties such as tunable band gap, narrow‐band emission and high charge mobility, they are quite promising in various fields including liquid‐crystal display backlighting, solid‐state lighting and other energy conversion applications. However, the intrinsic low formation energy makes them vulnerable to external stimulus, e. g. water, oxygen, heat, etc. Among many methods, swelling‐deswelling microencapsulation emerges as one of the most promising strategies to improve their stability. Herein, recent developments and future research directions in swelling‐deswelling microencapsulation‐enabled ultrastable perovskite−polymer composites are summarized. We believe this strategy has great potential to deliver successful perovskite‐based commercial products for many photonics applications.
