This study reports the synthesis and characterization of new type π-conjugated poly(2,5-didodecyloxy-1,4- diethynyl-phenylene-alt-2-N,N-dimethyl amino-4,6-pyrimidine) with good acidochromism. This polymer was prepared by polycondensation of Sonogashira. Sonogashira was a general route for the preparation of arylacetylenes by coupling an alkynes with aryl or alkenyl halide (or triflates). There were very well solubility for the derivatized copolymer in general organic solvents and exhibits good thermal stability. The copolymer emits blue light under UV irradiation of the solution phase and when protonated with an organic acid, the copolymer exhibits a red shift. In addition, was detected that the copolymers with good acidochromism with acidic place. It was expected to used for acid recognition.
Materials Chemistry and Physics published new progress about 56-05-3. 56-05-3 belongs to pyrimidines, auxiliary class Pyrimidine,Chloride,Amine,API, name is 2-Amino-4,6-dichloropyrimidine, and the molecular formula is C4H3Cl2N3, Safety of 2-Amino-4,6-dichloropyrimidine.
