Herein the enantio-selective polymerization of diacetylene (DA) units in the discotic hydrogen-bonding complex is carried out in an asymmetric reaction field consisting of the lamellar columnar LC phase and CPUL stimulus.

An optical waveguide based on a PDA microtube has been prepared through a novel hierarchical assembly method. The waveguide performance of the PDA microtube can be easily modulated upon external stimuli. The polarization of the out-coupled emission light seems independent of the propagation distance, which should be ascribed to the ordered alignment of PDA chains in the microtube.

A novel crown functionalized diacetylene monomer, N-(2,3,5,6,8,9,11,12octahydrobenzo[b][1,4,7,10,13] pentaoxacyclopentadecin-15-yl) pentacosa-10,12-diynamide (BCDA), was synthesized successfully. The copolymerized composite vesicles of BCDA and 10,12pentacosadiynoic acid (DA) with embedded receptor sites for metal ions have been prepared and characterized. Their response to the presence of metal cations in aqueous solution has been investigated by monitoring changes of color and UV-vis absorption. Upon addition of a series of alkali, alkaline earth and transition metal cations such as
