A multi-functional liposome has been developed that demonstrates reversible changes in color and fluorescence intensity in response to changes in pH. Addition of a pendant tryptophan moiety gives the assembly the ability to detect Escherichia coli. The sensor platform is made from a polymerized vesicular assembly of hydrazide-terminated diacetylene lipids and a BO558 fluorescent dye. The polymer backbone...
We structurally designed and synthesized a novel class of self-layered supramolecular polymers containing DA derivatives that can be obtained as film-forming materials and processed into a various forms. We found that double H-bonds between the acid hard cores together with a remarkable molecular DA recognition allow for retaining more favorable packing of the reactive groups in spin-coated films...
Polydiacetylenes (PDAs) are ordered and uniquely conjugated polymers synthesized from diacetylene monomers by UV-initiated photoreaction or thermally. The amphiphilic PDAs with controlled spacing and orientation often accomplished by Langmuir–Blodgett (LB) technique provide possible applications in the area of the photolithography, nonlinear optics and chemical sensors. In this study, we synthesized...
