The article was titled 《Fluorinated dendritic silicon (IV) phthalocyanines nanoparticles: Synthesis, photoinduced intramolecular energy transfer and DNA interaction》, and you may find the article in Dyes and Pigments.Category: nitriles-buliding-blocks The information in the text is summarized as follows:
Two series of fluorinated and non-fluorinated dendritic silicon (IV) phthalocyanines with cyano/nitro/ester terminal functionalities have been synthesized. Their structures were characterized by elemental anal., FT-IR, 1H NMR and ESI-MS. The effects of fluorinated groups and terminal functionalities properties on the photophys. properties, photoinduced intermol. electron transfer and intramol. energy transfer of silicon phthalocyanines were compared. In order to endow water soluble and biocompatibility to these silicon phthalocyanines, an amphiphilic diblock copolymer polyethylene glycol monomethyl ether-polycaprolactone was used to encapsulate these silicon phthalocyanines to form fluorinated and non-fluorinated dendritic silicon phthalocyanines nanoparticles. The binding model between the fluorinated dendritic silicon phthalocyanines nanoparticles and calf thymus DNA was studied by UV-Vis and fluorescence spectroscopic method. The photocleavage DNA activities of three fluorinated dendritic silicon phthalocyanines nanoparticles were compared and the possible cleavage mechanism was proposed. In addition to this study using 4-Cyanobenzyl bromide, there are many other studies that have used 4-Cyanobenzyl bromide(cas: 17201-43-3Category: nitriles-buliding-blocks) was used in this study.
4-Cyanobenzyl bromide(cas: 17201-43-3) is a white solid. Its melting point is 113-117°C, and flash point is 125.1°C. It is insoluble in water at 20°C. It is stable under normal temperatures and pressures. It should be stored at 0-5°C.Category: nitriles-buliding-blocks
