Polymerization of a phenylacetylene monomer bearing a dendron moiety was carried out by using a rhodium complex Rh[Cl2]2 as catalyst. The structure of the resultant was characterized with infrared, nuclear magnetic resonance, and UV-visible absorption spectroscopic techniques; the experimental data confirmed the generation of the expected polyphenylacetylene derivative (P1) with dendron pendants.

We attached for the first time -NOBIN to Frechet-type dendron units. The syntheses of 16 kinds of dendrimer-based NOBIN Schiff-base ligands were achieved in a straightforward manner by simple condensation of -NOBIN with the corresponding salicylicaldehyde derivatives, of which 12 belong to the dendritic Schiff-base ligands and 4 belong to the non-dendritic Schiff-base ligands.

通过手性拆分获得了光学纯化合物NOBIN，首次将NOBIN手性单元连接到树枝状大分子中去，设计合成了四个系列16种新的NOBIN衍生的希夫碱三齿手性配体，其中4种为非树枝状手性希夫碱配体，12种为树枝状手性希夫碱配体。

A novel series of naphthalimide dendrimers has been synthesized, into whose dendron novel specific function units are introduced. The absorption and fluorescence properties of the arrays were studied and discussed. Excitation of the terminal donor chromophores carbazole mainly results in the fluorescence of the core dye alone, whose efficiency is dependent on the dendrimer generation.

在树枝上引入特定的功能单元，将多个具有特定功能团连接起来，形成功能化树枝状周边分子团簇，然后将它们分别与核心色素萘酰亚胺相连接，合成新型周边树枝状功能化的有机发光材料。

These dendritic NOBIN derived Schiff base ligands have been applied to titanium catalyzed hetero-Diels-Alder reaction of Danishefshy's diene and aldehydes, affording the corresponding 2-substituted 2, 3-dihydro-4H-pyran-4-one in quantitative yields and excellent enantioselectivities (up to 97. 2%ee). Comparing the reactivities and enantioselectivities of reaction catalyzed by the titanium complexes of these Schiff base ligands, it was found that a series of ligands L〓 were superior to the other three series of ligands L〓, L〓 and L〓, a significant positive NLE and a dendrimer effect existed in the L〓 dendritic catalyst system. The disposition of the dendritic wedges and the dendron size in the ligands were observed to have a significant impact on the enantioselectivity of the reaction.
