| Outline of Final Research Achievements |
The synthesis of the polymers consisting of squaramide as a component of main chain has not been reported. If such polymers can be synthesized, the property is expected to be very interesting. We now report the synthesis of polysquaramide under a variety of conditions. When 1 was polymerized with LiHMDS in dry THF at 40 °C for 99 h, 1 was almost consumed and the molecular weight of the obtained product was higher than 1. We investigated the structure of obtained products (Mn = 670, Mw = 730), but it did not match the expected structure, such as oligomers or cyclic compounds. Accordingly, the condensation reaction between 2 and 3 was carried out as a model reaction to clarify the polymerization behavior. It revealed that the base was reacted with 3 under any conditions. Currently, we are the synthesis of squaramide oligomers by stepwise condensation reaction.
