We highlight and explore recent advances in the design of debonding on demand soft matter materials based on the azo-motif. While azo-motifs are most frequently exploited for their light induced cis/trans isomerization behavior, we herein focus on their arguably less-known function as a cleavable linker. We demonstrate that the use of azo-units as cleavable linkers provides access to a rich chemistry of materials, rapidly establishing their place in the field of adaptable soft matter materials design. Critically, we identify the outstanding challenges that will equip the degradable nature of the azo-unit with to-date inaccessible property profiles including light gated on/off switches, allowing soft matter materials to be cleaved depending on specific colors of light.

未开发的按需脱胶潜力：偶氮化合物的奇妙世界

我们重点介绍并探索基于偶氮基序的按需剥离软质材料设计的最新进展。虽然偶氮基序因其光诱导的顺式/反式异构化行为而最经常被利用，但我们在此集中于其可争议的作为可裂解连接子的鲜为人知的功能。我们证明了使用偶氮单元作为可裂解的连接基提供了获得丰富的材料化学的途径，从而迅速确立了它们在适应性软物质材料设计领域中的地位。至关重要的是，我们发现了巨大的挑战，这些挑战将使偶氮单元的可降解特性具有最新的难以接近的特性，包括光控开/关开关，从而可以根据光的特定颜色来切割软物质。
