Abstract This review focuses on recent advancements regarding mechanoresponsive functions of diacetylene (DA) and polydiacetylene (PDA). Their ability to undergo pronounced topochemical polymerization chromatic behavior variations in response external stimuli has marked them as a promising platform for chemo- bio-sensing over the past few decades. Notably, major advances, showcasing selective highly sensitive mechanoresponses along with their quantitative analysis, have been achieved years. The categorization includes DAs undergoing pressure-controlled crystalline transitions polymerization, well PDAs exhibiting mechanochromic or mechanofluorochromic transitions. Accordingly, this covers molecular designs allowing mechanical activation nanostructured hybridized amplifying stimulus-optical feedback, nanoscopic analytical tools mechanochromism, potential applications mechanochemical sensing imaging.
