A fluorescent monomer-free one-step strategy is developed for the synthesis of fluorescent acrylamide gels, using inexpensive and commercially available rhodamine B as the hydrogen donor in a type II photoinitiation system. The obtained hydrogels are fluorescent and have limited fluorophore leaching over time, due to the covalent bond formed between the polymer network and rhodamine dye.

无荧光单体的荧光水凝胶的光诱导合成

开发了一种无荧光单体一步法合成荧光丙烯酰胺凝胶，使用廉价且市售的罗丹明 B 作为 II 型光引发系统中的氢供体。由于聚合物网络和罗丹明染料之间形成共价键，所获得的水凝胶具有荧光性并且随着时间的推移具有有限的荧光团浸出。
