采用开环歧化聚合(ROMP)技术制备了一系列具有不同光致变色二硫乙烯(DTE)结构的均聚物和共聚物。每个DTE结构可以在两组分和三组分共聚物中唯一地寻址，从而提供了一种当化合物被选择性地光环化为其闭环形式时产生广泛颜色的方法。这种类型的多组分、可多寻址材料对于诸如多状态光致变色记录、显示器、油墨和条形码的应用是有益的。
A series of homo- and copolymers containing different photochromic dithienylethene (DTE) architectures was prepared by ring-opening metathesis polymerization (ROMP) techniques. Each DTE structure can be uniquely addressed in the two- and three-component copolymers, providing a means to generate a wide range of colors when the compounds are selectively photocyclized to their ring-closed forms. Multicomponent, multiaddressable materials of this type are beneficial for applications such as multistate photochromic recording, displays, inks, and barcodes.
