Self-immolative polymers are an emerging class of macromolecules with distinct disassembly profiles that set them apart from other general degradable materials. These polymers are programmed to disassemble spontaneously from head to tail, through a domino-like fragmentation, upon response to extremal stimuli. In the time since we first reported this unique type of molecule, several groups around the world have developed new, creative molecular structures that perform analogously to our pioneering polymers. Self-immolative polymers are now widely recognized as an important class of stimuli-responsive materials for a wide range of applications such as signal amplification, biosensing, drug delivery, and materials science. The quinone-methide elimination was shown to be an effective tool to achieve rapid domino-like fragmentation of polymeric molecules. Thus, numerous applications of self-immolative polymers are based on this disassembly chemistry. Although several other fragmentation reactions achieved the function requested for sequential disassembly, we predominantly focused in this Perspective on examples of self-immolative polymers that disassemble through the quinone-methide elimination. Selected examples of self-immolative polymers that disassembled through other chemistries are briefly described. The growing demand for stimuli-responsive degradable materials with novel molecular backbones and enhanced properties guarantees the future interest of the scientific community in this unique class of polymers.

Photoluminescence materials play an inseparable role in the application of polymer systems. However, intrinsic polymer systems have rarely been intuitively interpreted based on photoluminescence regulation. A novel photoluminescence mechanism called vibration-induced emission (VIE) has recently drawn great attention due to its multicolor fluorescence from a single molecular entity. Based on the unique fluorescent properties of VIE molecules, we have doped 9,14-diphenyl-9,14-dihydrodibenzo[a,c]-phenazine (DPAC) and its derivative DPAC-CN in two stretchable polymers, poly(ε-caprolactone) and ethylene vinyl acetate (EVA) copolymer, to explore the important relationship between luminophores and polymer systems. This research focuses on the multicolor photoluminescence of the obtained blend films that resulted from stretching exertions and temperature responses. The successive conformational alterations of VIE molecules endow continuous photoluminescent changes. Meanwhile, the multicolor variations also provide specific visual evidence regarding the amplified tensile stresses and microstructural changes in the polymer. This demonstration therefore provides advantageous insights into the development of functional optical materials.
