Polyaldehyde (polyal) dendrimers were synthesized by a divergent iterative method using 1,3,5-triethynylbenzene (1) as the core unit and 2-bromo-5-tert-butyl-1,3-benzenedicarbaldehyde (2) as the building block. The polyal dendrimers were further transformed into a new class of polyene and polyyne dendrimers. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
以 1,3,5-三乙炔基苯 (1) 为核心单元,2-溴-5-叔丁基-1,3-苯二甲醛 (2) 为结构单元,通过发散迭代法合成了聚醛 (polyal) 树枝状聚合物. 聚醛树枝状聚合物进一步转化为一类新的多烯和聚炔树枝状聚合物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
