  Tuning Down of Color Transition Temperature of Thermochromically Reversible Bisdiynamide Polydiacetylenes

  摘要：

  A series of bisdiynamide lipids containing various lengths of methylene spacer (m = 2, 3 and 4) between the diynes and the diamide headgroup and number of methylene units (n = 6 and 9) in their hydrophobic tails are synthesized. All six lipids synthesized can be dispersed in water and photopolymerized by UV irradiation to give the corresponding polydiacetylene (PDA) sols. The color transitions from blue to red during heating-cooling cycles of the PDA sols are photographically recorded and monitored by UV-vis absorption spectroscopy. The bisdiynamide PDAs exhibit excellent thermochromic reversibility and the color transition temperature can be tuned between ca. 25-55 degrees C by the variation of m and n values. Temperature indicators can be obtained by applying a screen printing ink formulated from the bisdiynamide monomer on plastic substrates followed by UV irradiation to generate desired patterns of thermochromically reversible PDAs.

  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.

  提供了一种新型水溶性二炔基单体，包括该新型水溶性二炔基单体和导电聚合物的光刻组合物，以及使用该组合物形成微图案的方法。即使与水溶性导电聚合物混合，水溶性二炔基单体也不会聚集。因此，通过将水溶性导电聚合物与二炔基单体混合，可以制备用于光刻的均匀组合物，并且可以使用该组合物形成微图案。更具体地说，当将组合物形成薄膜后，然后用光照射时，只有二炔基单体的经光辐射部分由于光聚合而选择性交联，从而形成不溶性负型微图案。

  Ingestible compositions comprising a chromic change agent together with methods of making and using them are provided. The chromic change agent alternatively may be associated with the ingestible, such as a packaging material for the ingestible. In response to a triggering event, physical or chemical, the chromic change agent changes color to provide information as to the history of the ingestible, either prior or contemporaneous with use. Depending on the use, the color change agent may be reversible or irreversible. Various solid or liquid ingestible compositions are provided for determining ingestible temperature, storage temperature, user temperature, light exposure, pH change, hydration or solvation change, mechanical stress, and the like, particularly in comestibles. Of particular interest are polydiacetylene polymers that may be formulated to provide compositions having numerous different color transition triggering mechanisms. The invention is also related to other chromic change agents that may be incorporated into ingestibles.
