A Reversibly Solvatochromic Polydiacetylene |
| 초록 |
The development of a polydiacetylene (PDA) with colorimtric reversibility has gained enormous interest for several decades. However, the majority of reported reversible PDAs are thermochromically reversible. PDAs with reversible solvatochromism are rarely reported. We designed a new diacetylene monomer MCDA-TA that is macrocyclic and contains four carboxylic acid. The PDA derived from MCDA-TA displayed a blue-to-wine red color change upon exposure to chloroform. Very interstingly, the chloroform exposed PDA returned to the initial blue color when chloroform was evaoprated. This is an unusual phenomenon and we believe the reversible solvatochromism is due to the balanced solubility of the diacetylene monomer in the exposed solvent. Hansen parameter was used to determine the difference between reversibly and irreversibly solvatochromic PDAs. |
