Provided are a novel water-soluble diacetylene monomer, a composition for photolithography including the novel water-soluble diacetylene monomer and a conductive polymer, and a method of forming micropatterns using the composition. The water-soluble diacetylene monomer may not aggregate even when mixed with a water-soluble conductive polymer. Accordingly, a uniform composition for photolithography can be prepared by mixing a water-soluble conductive polymer with the diacetylene monomer, and micropatterns can be formed using the composition. More particularly, when the composition is formed into a thin film and then is irradiated with light, only light-irradiated portions of the diacetylene monomer are selectively crosslinked due to photopolymerization, thereby resulting in insoluble negative-type micropatterns.

be useful in sensing local environmental changes, we have synthesized a series of novel diacetylene-containing amide and urea derivatives using d-glucosamine as the starting material. Both amphiphilic and dipolar glycolipids were synthesized, and these compounds are effective gelators for several organic solvents and aqueous solutions. The resulting gels can be cross-linked under 6 W UV light to produce

The colorimetric reversibility of polydiacetylene supramolecules, derived from a variety of functionalized diacetylenic lipids, has been subjected to detailed investigation. In an earlier effort, it was shown that polydiacetylene vesicles prepared from PCDA-mBzA 1, bearing terminal m-carboxyphenylamido groups, display complete reversibility upon thermal stimulation [J.

transition temperatures of the PDAs were found to decrease by ca. 10 °C when the alkyl chain length in the DA monomer is truncated by two methylene units. The results of FTIR and Raman spectroscopic analyses suggest that the PDA alkyl chain adopts an all-trans conformation in the blue-phase and some gauche forms exist in the alkyl chain in the red-phase PDA. Finally, the new PDAs are stable up to 300 °C,
A method of imparting color to a plastic substrate comprising applying to the substrate, or incorporating within the substrate, a diacetylene compound of general formula (I) wherein n=1 to 20; R1=an optionally substituted C1-20 alkyl group which may contain heteroatoms; T=H, an optionally substituted C1-20 alkyl group which may contain heteroatoms or —(CH2)m—C(═O)-Q2R2; Q1=NH, CO, NHCONH, OCONH, COS, NHCSNH or NR3, wherein m, Q2 and R2 are independently selected from the same groups as n, Q1 and R1 respectively; R3 is an optionally substituted C1-20 alkyl group which may contain heteroatoms; and irradiating the substrate to impart color to the substrate is described.
