用简单的反应途径合成了一种可聚合的溶剂致变色染料单体。该染料单体与NiPAAM共聚形成具有较低临界溶液温度（LCST）行为的溶剂致变色共聚物。由此产生的共聚物通过红橙色变化(a) LCST相变和(b)环糊精与该共聚物的主客体相互作用仅通过肉眼可见。实际上，这些影响是完全可逆的。
With a simple reaction pathway, a polymerizable solvatochromic dye monomer was synthesized. Copolymerization of this dye monomer with NiPAAM leads to formation of a solvatochromic copolymer with lower critical solution temperature (LCST) behavior. This resulting copolymer visualizes via a red-orange color change (a) the LCST phase transition and (b) the host-guest interaction of cyclodextrin with this copolymer simply by the naked eye. Actually, these effects are completely reversible.
