A novel functional 2,6-substituted donor-acceptor anthracene derivative, bearing a long alkyl spacer and a polymerizable end-group, is synthesized from readily available compounds. This monomer possesses conjugated electron donor and acceptor moieties to achieve UV absorption and anthracene dimerization at higher wavelengths and under milder conditions, than anthracene and other reported anthracene
由容易获得的化合物合成了带有长烷基间隔基和可聚合端基的新颖的2,6-取代的供体-受体蒽衍生物。与蒽和其他报道的蒽衍生物相比,该单体具有共轭电子给体和受体部分,可在更高的波长和更温和的条件下实现紫外线吸收和蒽二聚。与大多数9-取代的蒽相比,该化合物在更高的波长处吸收并二聚更快。研究了二聚体的快速光化学断裂和相对较慢的热断裂,并且与化学结构即2,6-取代有关。
