  Nematic Dendrimers Based on Carbosilazane Cores

  摘要：

  The controlled synthesis of nematic nanophase-separated materials poses an attractive synthetic challenge. The use of carbosilazane multipodes and dendrimers (such as 1) in conjunction with laterally attached mesogens allows the systematic investigation of the structure-property relationships of room-temperature nematic liquid crystals.
