Main chain which composed of phenol unit connected by methylene unit at 2,6-position of phenol was proposed. Boroinc acid and 1,3-diol unit could be introduced into the main chain and tri-boronic acid and tetrol was successfully prepared. Boronic ester formation was examined between those units, however, soluble products could not be obtained. Introduction of long alkyl chains did not affect the results. Next, main chain, whose freedom is reduced was prepared and studied the boronic ester formation again. This time soluble product would be obtained and the structure of the soluble oligomer is now studied in detail now.

提出了由苯酚单元与苯酚2，6位亚甲基单元连接而成的主链。主链上引入硼酸和1,3-二醇单元，成功制备出三硼酸和四醇。在这些单元之间检查了硼酯的形成，然而，无法获得可溶性产物。引入长烷基链并不影响结果。接下来，制备自由度降低的主链并再次研究硼酸酯的形成。这次将获得可溶性产物，并且现在详细研究可溶性低聚物的结构。
