Green synthesis of dihydropyrano[3,2-c]chromene derivatives using amino-terminated PAMAM dendrimer as catalyst

Autor: V. Unnikrishnan, Kiran James, G. Avudaiappan, Krishnapillai Sreekumar, M. R. Palmurukan

Publikováno v: Research on Chemical Intermediates. 48:379-399

d-Sorbitol-cored PAMAM dendrimer (SOR-G1) was effectively synthesized by the ring opening polymerization of epichlorohydrin. The dendrimer was characterized using different spectroscopic and analytical techniques including IR and NMR spectroscopy, TG

Azide functionalized porphyrin based dendritic polymers for in vivo monitoring of Hg2+ ions in living cells

Autor: Krishnapillai Sreekumar, Mariya Vibija J, G. Avudaiappan

Publikováno v: Analytical Methods. 12:2995-3003

A porphyrin cored azide functionalised dendritic polymer was developed as a selective sensor for in vivo monitoring of mercuric ions in living (normal and cancer) cells and in an aqueous medium. The developed sensor could sense mercuric ions even at

A polyamine dendritic polymer–copper complex: a reusable catalyst for the additive-free amination of aryl bromides, and iodides

Autor: V. Unnikrishnan, Krishnapillai Sreekumar, M. R. Palmurukan, G. Avudaiappan

Publikováno v: New Journal of Chemistry. 44:1477-1484

A porphyrin-initiated amine-functionalized polyepichlorohydrin dendritic polymer (PPECH–Amine) was effectively synthesized, and its water-soluble copper complex (PPECH–Amine–Cu) was developed by treating it with copper acetate. PPECH–Amine an

A novel dendritic polymer based turn- off fluorescence sensor for the selective detection of cyanide ion in aqueous medium

Autor: A.M. Shebitha, Letcy V. Theresa, K. Hiba, K. Anjaly Jacob, G. Avudaiappan, Krishnapillai Sreekumar, Priya K. Shenoi, V. Unnikrishnan

Publikováno v: Reactive and Functional Polymers. 137:71-78

Porphyrin cored polyepichlorohydrin (POR-PECH) dendritic polymer was identified as an efficient turn-off fluorescence probe for selective determination of cyanide ion in aqueous medium. The dendritic polymer showed strong red fluorescence at 656 and

Multifunctional polyether grafted dendritic solid supports: Novel class of solvent like high loading hybrid supports for solid phase organic synthesis

Autor: G. Smitha, Krishnapillai Sreekumar, K.J. Anjaly, G. Avudaiappan

Publikováno v: Reactive and Functional Polymers. 166:104985

Three novel multifunctional polyether grafted dendritic solid supports for organic synthesis were developed via single step, grafting from and hypergrafting strategies. In order to improve both the swelling capacity and loading capacity of convention
