The rapid solution phase synthesis of novel liquid crystalline materials is demonstrated by utilising combinatorial and parallel methods for the preparation of a library of 225 differently fluorinated 4,4‴-dipropyl-p-quaterphenyls. Chemical diversity was introduced into the growing oligomers via a convergent synthetic sequence of iodinations and Suzuki cross-couplings by using various fluorinated phenyl building blocks. A highly efficient rapid parallel purification method was developed that provided HPLC-pure library members in amounts sufficient for the characterization of bulk properties.
通过利用组合和并行方法快速合成新型液晶材料,展示了225种不同氟化的4,4‴-二丙基-p-四苯基的文库的制备。通过使用各种氟化苯基构件,采用亲核取代和铃木交叉偶联的汇聚合成序列,将化学多样性引入生长中的低聚物中。开发了一种高效的快速并行纯化方法,能够提供足够量的HPLC纯库成员,以便对整体特性进行表征。
