Abstract:
Serial novel chiral polydiacetylenes (PDAs) are efficiently prepared at room temperature by the controllable electrophoretic deposition of diacetylenes with tunable structure as designed from easily available starting materials. The colorimetrically reversible properties of PDAs in the range between 25 and 85 °C are influenced by the different amino acid moiety in the PDAs as anticipated. The PDA containing aromatic ring is much better for the colorimetrically reversible properties, while irreversible thermochromism is displayed for the PDA with the structure of the longer methylene units in the main chain of amino acid moiety.

Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
