Porphyrin dendrimers with boronic ester, aldehyde, and pyridil termini were synthesized and fully characterized. These dendrimers have the potential to change their physical and chemical properties by reversible alteration of the reactive terminal groups.

The synthesis of macrocycles comprising a 1,1′-bis(phenylethynyl)ferrocene subunit was developed to increase the structural control over the spatial arrangement of the two cyclopentadienyl ligands of the ferrocene junction. The target structures were obtained through a modular strategy that enables the assembly of varying ring sizes from a common precursor. In particular, macrocycles were either formed
开发了包含 1,1'-双(苯基乙炔基)二茂铁亚基的大环的合成,以增加对二茂铁连接的两个环戊二烯基配体的空间排列的结构控制。目标结构是通过模块化策略获得的,该策略能够从常见的前体组装不同的环尺寸。特别是,大环是通过醚形成反应或闭环复分解反应形成的。大环以合理的分离产率获得,这使得它们可以通过一维和二维 NMR 光谱实验进行彻底表征,并且单晶 X 射线衍射证实了一个大环的身份。

Novel benzylether type aldehyde and acetal terminated dendrons were synthesized and attached to a silica gel support; a linear spacer was also introduced as a control material. The supported dendritic compounds were mainly characterized by solid state 13C CPMAS NMR, elemental analysis and X-ray photoelectron spectroscopy (XPS) and the presence of free aldehydes was determined by the purpald test. Bovine serum albumin (BSA) protein was coupled to the dendronized support by imine bond formation, followed by irreversible reduction of the carbon–nitrogen double bond. A significant positive dendritic effect was observed on the antibody binding capacity of immobilised BSA as measured by fluorescence immunoassay (FIA).
