摘要:Abstract(#br)Traditional amine terminated PAMAM dendrimers may be readily surface engineered by a facile one-pot conversion with dialkyl itaconate esters into 4-carbomethoxypyrrolidone terminated PAMAM (G

摘要:Abstract(#br)The phosphite-mediated coupling of two benzaldehydes into 2,2,2-triethoxy-1,3,2-dioxaphospholanes was investigated using 13 C NMR spectroscopy and was found to be very sensitive to the nature of the ortho / para substituents, and promoted by electron-withdrawing grou...

摘要:Abstract(#br)Improved synthetic methodology for the synthesis of internally branched chiral poly(amidoamine) (PAMAM) dendrons and dendrimers has been developed and the compounds have been characterized by NMR spectroscopy, IR spectroscopy, and optical rotation measurements. The d...

摘要:Abstract(#br)Cytotoxicity of cationic amino-terminated PAMAM dendrimer and modified PAMAM-pyrrolidone dendrimer was compared. LDH assay and cell visualization technique were employed. Mouse embryonic hippocampal cells (mHippoE-18) were used. The experiments were performed in FBS-...

摘要:Abstract(#br)Modification of the surface groups of dendrimers is one of the methods to improve their biocompatibility. This article presents results of experiments related to the toxicity of a modified polyamidoamine (PAMAM) dendrimer of the fourth generation with 4-carbomethoxyp...

摘要:Controlled alignment and self‐assembly of molecular wires is one of the challenges in the field of molecular electronics. Here, we take an approach by which two oligo(phenyleneethynylene)s (OPEs) are linked together through one vinylogous linker. These molecules thus incorpo...
