Description
Technical field
The present invention relates to polymer chemistry and material science, be specifically related to a kind of novel hyperbranched poly triazole manthanoate.
Background technology
The sixties in 20th century, Germanization scholar Rolf Huisgen has at first studied and has utilized 1 of organic nitrine and alkynyl compounds preparation ring triazole class compounds, 3-Dipolar Cycloaddition (Chem.Ber.1967,100,2494).But, make this reaction not be used widely because speed of reaction is slow and product does not have stereoselectivity.2002, Meldal and Sharpless seminar independently reported the cycloaddition reaction of the catalytic nitrine-alkynyl of cuprous salt respectively, and the discovery speed of reaction is accelerated greatly, and product has stereoselectivity; Only generate 1, the dibasic 1,2,3-triazoles compound of 4-(J.Org.Chem.2002; 67,3057, Angew.Chem.; Int.Ed.2011,40,2004).Immediately, Sharpless etc. should react called after " click chemistry " reaction.
The characteristics of " click " reaction are that reaction conditions is simple, and raw material is easy to get, and reaction has very strong stereoselectivity and meets Atom economy etc.Cycloaddition reaction conduct typical " click " reaction of the catalytic nitrine-alkynyl of cuprous salt, it is synthetic to be widely used in functional polymer, finishing, a plurality of fields such as preparation of biology and chemical sensor.
Aspect polymkeric substance synthetic, the cycloaddition reaction of the catalytic nitrine-alkynyl of monovalence copper is used for the back functional modification of polymkeric substance morely.Should react as a kind of polyreaction and prepare polymkeric substance, especially the research of hyperbranched polymer aspect is less.2004, people such as Voit attempted utilizing AB
2The type monomer prepares hyperbranched polymer under the catalysis of copper sulfate and sodium ascorbate, but has had to insoluble polymkeric substance (Macromol.Rapid Commun.2004,25,1175).2008, Katritzky seminar utilized A through changing monomer type

3The type monomer has prepared soluble hyperbranched polymer (Macromolecules 2009,42,1589, J.Polym.Sci., PartA:Polym.Chem.2011,49,1977) under the catalysis of copper sulfate and sodium ascorbate.
The catalytic click polyreaction of monovalence copper prepares hyperbranched polymer, often causes the solvability of polymkeric substance relatively poor, and residual copper catalyst is difficult to remove clean in the polymkeric substance.If this base polymer is used for biomedicine and photoelectric field; Will produce the photophysical property of cytotoxicity and destruction polymkeric substance; Thereby limited the application of the catalytic click polyreaction of monovalence copper, the click polyreaction that therefore develops no metal catalytic prepares hyperbranched polymer and has very important science and using value.
In addition, most of luminous organic materials can present luminous efficiency usually to be reduced even non-luminous phenomenon in state of aggregation or when solid-state, promptly assembles fluorescent quenching, and this has just limited the range of application of luminous organic material greatly.
Calendar year 2001; This loyal seminar of Tang finds that silole is not luminous when solution; And when solid-state, present (Chem.Commun.2001,1740) after the very strong characteristics of luminescence, with luminous (the Aggregation-induced emission of this phenomenon called after aggregation inducing; AIE): i.e. emitting fluorescence not under solution state, and fluorescence strengthens under state of aggregation.Since finding the AIE phenomenon; A series of small molecules with AIE performance and linear, a chain polymkeric substance are synthesized out; And be widely used in a plurality of fields (Chem.Commun.2009,4332) such as analyzing and testing, bio-sensing and electroluminescent device as fluorescent probe and electroluminescent material.Polymkeric substance than other type; Hyperbranched polymer is owing to have highly branched three-dimensional ball-like structure and many functionality end groups; And show numerous excellent specific properties, like LV, no chain entanglement and good consistency, and its compound method is simple; Cost is low, so hyperbranched polymer has important use value in fields such as coating, processing aid, biological medicine carrier, photoelectric functional material, Journal of Molecular Catalysis and reactor drums.But it is less that up to the present, preparation has the report of the active hyperbranched polymer of AIE.Our seminar adopts A recently
