The synthesis of the 1st generation dendrimer 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CPh)(dppe)(2) (C≡CC(6) H(4) -4-(E)-CHCH)])(2) C(6) H(3) )(dppe)(2) (C≡CC(6) H(4) -4-(E)-CHCH)]}(3) C(6) H(3) proceeds by a novel route that features Emmons-Horner-Wadsworth coupling of 1,3,5-C(6) H(3) (CH(2) PO(OEt)(2) )(3) with trans-[Ru(C≡CC(6) H(4) -4-CHO)Cl(dppe)(2) ] and 1-I-C(6) H(3) -3,5-(CH(2) PO(OEt)(2) )(2) with trans-[Ru(C≡CPh)(C≡CC(6) H(4) -4-CHO)(dppe)(2) ] as key steps. The stilbenylethynylruthenium dendrimer is much more soluble than its ethynylated analog 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CPh)(dppe)(2) (C≡CC(6) H(4) -4-C≡C)])(2) C(6) H(3) )(dppe)(2) (C≡CC(6) H(4) -4-C≡C)]}(3) C(6) H(3) and, in contrast to the ethynylated analog, is a two-photon absorber at telecommunications wavelengths.
第一代树枝状大分子1,3,5-{反式-[Ru(C≡C-3,5-(反式-[Ru(C≡CPh)(dppe)(2)(C≡CC(6)H(4)-4-(E)-CHCH)])(2)C(6)H(3))(dppe)(2)(C≡CC(6)H(4)-4-(E)-CHCH)]}(3)C(6)H(3)的合成通过一条新路线进行，该路线的关键步骤包括1,3,5-C(6)H(3)(CH(2)PO(OEt)(2))(3)与反式-[Ru(C≡CC(6)H(4)-4-CHO)Cl(dppe)(2)]的埃蒙斯-霍纳-沃兹沃思偶联以及1-I-C(6)H(3)-3,5-(CH(2)PO(OEt)(2))(2)与反式-[Ru(C≡CPh)(C≡CC(6)H(4)-4-CHO)(dppe)(2)]的偶联。与乙炔基化类似物1,3,5-{反式-[Ru(C≡C-3,5-(反式-[Ru(C≡CPh)(dppe)(2)(C≡CC(6)H(4)-4-C≡C)])(2)C(6)H(3))(dppe)(2)(C≡CC(6)H(4)-4-C≡C)]}(3)C(6)H(3)相比，苯乙烯基乙炔基钌树枝状大分子的溶解性要好得多，并且与乙炔基化类似物不同，它在电信波长下是一种双光子吸收剂。
