“…and length of the final product. The examples of such an effort have been reported by two groups, Gatebe et al 37 and Tong et al, 38 using the nano-porous templates of aluminium oxide. The former has employed layer-by-layer deposition of DA monomer 10,12-docosadiyndioic acid (9) on the pre-zirconated samples of the alumina template.…”

While a large variety of conjugated polymers exist, polydiacetylenes (PDAs) remain a major research area among scientists due to their interesting optical, spectral, electronic, and structural properties. Heavily reviewed in regards to their stimuli responsive properties, much is known about the assortment of sensing and detection capabilities of PDAs. In this article, we look more upon the structural diversities of polydiacetylenes that have been achieved in recent years, particularly from a hierarchical perspective of 1, 2, and 3-dimensional configurations. In addition, we examine how these different dimensional arrangements of PDAs have heralded clear applications in several key areas. Successful integration of these stimuli-responsive "smart" materials into various geometries has required researchers to have a comprehensive understanding of both the fabrication and synthesis processes, as well as the signalling mechanism for the optical, fluorogenic or spectral transitions. The on-going discovery of new PDA formulations continues to provide interesting structural manifestations such as liposomes, tubes, fibres, organic/inorganic incorporated hybrids and composite structures. By highlighting some of the recent conceptual and technological developments, we hope to provide a measure of the current pace in new PDA derivative development as core components in efficient sensor, imaging and display systems.

View full text Add to dashboard Cite

Polydiacetylenes (PDAs) comprise a class of chromatic polymers which have attracted significant interest over the past 40 years as a promising platform for chemo-and bio-sensing. Specifically, the unique colorimetric and fluorescent transformations of PDA, induced by varied external stimuli, are a core property of these polymers, and have been widely exploited for diverse applications. In this review, we focus on recent developments in PDA chemistry, materials, and practical applications. We summarize the progress in development of new synthetic routes and assembly methods resulting in enhanced chromatic properties and interesting molecular configurations. We further outline the challenges that still exist for practical utilization of PDA technology, and possible future directions.
