In addition to the model compounds 4a and 4b, the dendrimers 11 and 14 with trans-stilbene chromophores in the core and on the periphery of the dendrons were prepared and their photochemistry was studied in solution and in neat films. Due to the flexibility of the arms, intramolecular and intermolecular CC bonds are formed on irradiation. Thus, the generation of nanoparticles, which represent small
除了模型化合物 4a 和 4b 之外,还制备了在核心和树枝外围具有反式二苯乙烯发色团的树枝状聚合物 11 和 14,并在溶液和纯薄膜中研究了它们的光化学。由于臂的柔韧性,在辐照时会形成分子内和分子间 CC 键。因此,代表小的低聚物的纳米颗粒的产生比刚性、交叉共轭的二苯乙烯树状大分子的交联更有可能。紫外和核磁共振光谱研究了溶液中的光反应,原子力显微镜研究了薄膜的转变。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
