Azo dyes, with their remarkable ability to form stable azo–metal chelate complexes with outstanding thermal and optical properties have been studied widely

In order for this polymerization to proceed, the molecules within the assembly must be oriented relative to each other following

Polydiacetylenes have interesting optical and electronic properties, and diacetylene containing gels may have useful applications as advanced sensing materials [35][40][41]. The morphologies of the self-assembled structures can be retained by

• these observations, we can see that the side chain alignment of compound 18A is quite favorable in providing long range order for the polymerization of the diacetylene groups. Typically polydiacetylenes exhibit absorptions near 530 nm and 630 nm depending on the side chain structures, and the color
