Abstract

The invention relates to the organic semiconductor field, and provides a fluorene based sulfonic acid type water / alcohol-soluble conjugated polymer and a preparation method thereof. The method comprises the following steps: reacting 2,7-dibromofluorene with an alpha, beta-unsaturated carbonyl compound under an alkaline condition to generate a sulfonic acid-containing dibromofluorene monomer; and carrying out a Suzuki reaction of the sulfonic acid-containing dibromofluorene monomer, a monomer with two ends having bromo groups and a monomer with two ends having different structures of borates under a weakly alkaline condition to synthesize the sulfonic acid-containing conjugated polymer. The sulfonate-containing functional monomer is synthesized through the above one step method, and the sulfonic acid monomer participating in the above reaction is cheap and can be easily obtained; and the polymer synthesis method has the advantages of simplicity, air insulation, no need of water insulation, and implementation of the reaction only through heating to 85-90DEG C.

Description

Technical field

[0001] The invention relates to the field of organic semiconductors, in particular to a fluorene-based sulfonic acid type water / alcohol soluble conjugated polymer and a preparation method thereof. Background technique

[0002] Since it was discovered in the 1970s that polyacetylene molecules were doped to make them a good conductor, more and more researchers have devoted themselves to semiconductor research. With the continuous deepening of research on organic semiconductors, it has been widely used in light-emitting diodes, solar cells, sensors, memories, resistors, capacitors, etc. With the continuous expansion of the scope of application, further requirements are put forward for the solubility of conjugated polymers.

[0003] Water / alcohol soluble conjugated polymer refers to the functionalized conjugated polymer containing hydrophilic groups (anions such as sulfonate and phosphate, cations such as ammonium and non-ion such as hydroxyl) in the molecular structur...
