This review describes the recent progress in the design and fabrication of polyacetylene-based chemosensors applicable to colorimetric and fluorescence anion sensing that has been increasingly demanded in diverse fields. The validity of polyacetylene derivatives as an anion sensor material has been demonstrated based on the evaluation of the anion-induced optical responses for various types of polyacetylenes with different binding sites and pendant structures. Suitable molecular designs of the polyacetylene have been found to exert a beneficial influence on the anion detection abilities, which are specifically highlighted in this review article.

“…80 According to the CD spectra, colorless THF solution of 62 does not take a one-handed helical conformation regardless of several chiral centers on the lysine dendron. Upon addition of CH 3 CO 2 ¡ or Cl ¡ , the CD spectrum of 62 shows an intense positive Cotton effect in a range of 340 to 630 nm, while the colorless polymer solution immediately turns to a red solution.…”

Combination of stimuli responsiveness with p-conjugated polymers possesses probabilities not only to provide these polymers with unique interesting properties but also to promote new functions including various optoelectronic properties, catalysis, ionic sensing, and chiral recognition. In the former part of this review, recent developments of stimuli-responsive polyacetylenes are surveyed, which act as receptors towards external stimuli such as solvent, temperature, pH, chiral compounds, metal cations, various anions, electricity, light, etc., to transduce to other signals or energies, which leads to a wide range of intriguing properties to mimic biological processes or applications to smart or intelligent materials. In the latter part, we introduce dendronized poly(phenylacetylene)s (PPAs) exhibiting interesting thermoresponsive and chiroptical properties. Thermoresponsiveness of these dendronized conjugated polymers shows synchronous influence on their helical and hydrated conformations.

“…Furthermore, Kakuchi et al [55] demonstrated that poly(phenylacetylene) bearing second generation lysine dendrons through urea groups 16 was a superior anion receptor possessing a stricter size specificity for colorimetric anion detection. On the addition of CH 3 CO 2 − , F − , and Cl − , an almost colorless polymer solution immediately turned red.…”
