Title: A new theoretical model for assessment of molar mass  in  type  dendrimers

Authors: Massoudi.A.H, Vahedi.H, Louie.O , Sajjadifar.S

Address: Payame nour University .Mashad. Iran



Dendrimers are architechral macromolecules with a lot of branches in three-dimensional and ordered structures. They have been prepared [1,2] via multistage reaction  in which  the  number of generations produced .The  number of generations are correspond to their  number of the rings . [4,3]

In this research the efficiency of   computational  molar mass  model of  the dendrimer with  alcoholic ,acidic ,amine and tert-Butyl acetate groups terminated in end branches were investigated. According  to our investigation a developed  model was obtained, in which  by the knowledge of molar masses of the core  ( ) and end branch groups ( ) and  number of  active sites in the  core ( ) ,molecular weight  of dendrimer  - type  was achieved .

Methylindolenines were prepared by fischer indole synthetic reaction of o,m-tolylhydrazinehydrochloride with methylisopropylketone and   2-methylcyclohexanone in acetic acid at room temperature in high yield.

o,p – Nitrophenylhydrazines were reacted with 2-methylcyclohexanone in acetic acid at reflux to give nitroindolenines , and the reaction of o,p – nitrophenylhydrazines with methylisopropylketone in acetic acid were not successful.

o,p – Nitrophenylhydrazines were reacted with methylisopropylketone in acetic acid , hydrochloric acid to give 2,3,3- trimethyl-5- nitro- indolenine and 2,3,3- trimethyl-7- nitro- indolenine
