Abstract: We prepare hydrogen-bonding complexes of the diacetylene derivatives 10,12-tricosadiynoic acid, 4,6-heptadecadiynoic acid, and ((E)-4-((4-(tricosa-10, 12-diynoyloxy)phenyl)diazenyl)benzoic acid and poly(4-vinylpyridine) in organic solvents. The complexes are spin-cast and form high-quality thin films, which can be photopolymerized and yield the blue phase of polydiacetylenes. A cross-linked network of the hydrogen-bonding complex is formed and shows improved stability to organic solvents. We demonstrate sensor capabilities for various organic solvents and gases by means of the blue-to-red color changes of polydiacetylenes. Based on the different solubility of the hydrogen-bonding complex before and after UV irradiation, photolithography can be employed to fabricate microstructures for polydiacetylene-based devices.

Abstract: We demonstrate a new strategy for improved stabilization of polydiacetylene micelles. They show temperature-induced color changes. which are fully reversible even at varying pH. A novel azo chromophore-functionalized amphiphilic diacetylene molecule is synthesized and used to prepare self-assembled cylindrical micelles. The micelles can be polymerized by 254 run light irradiation. The azo chromophores form H- and J-like aggregates in the polydiacetylene micelles and increase the stability of the micelles, which leads to fully reversible thermochromism of the micelles in the temperature range between 20 and 90 degrees C and the pH range between 5.6 and 9.6.
