Description
Technical field
The present invention relates to a kind of method for preparing oligo-thiophenes nanofiber by achiral oligo-thiophenes molecule with helical structure.
Background technology
Thiophenes is widely used in organic optoelectronic devices such as preparation organic effect diode, field-effect transistor, OTFT and photovoltaic cell owing to having semi-conductive electrology characteristic, optical, pliable and tough mechanicalness and machinability etc.Performance based on the electronic device of thiophenes preparation depends on mobility of charge carrier rate in the molecule, the i.e. movement velocity in electronics or hole.The principal element that influences mobility is the ability of charge carrier from a molecular transition to another molecule.Generally speaking, conjugated molecule is in mixed and disorderly state.The degree of order of arranging on the surface through the purity and the molecule of raising conjugated molecule can improve mobility of charge carrier speed, the operating rate of faster devices.The length that increases the thiophenes chain can improve mobility of charge carrier speed greatly, is 0.12cm like mobility of charge carrier speed in four polythiophenes

-1But the synthesis step of long-chain thiophene molecule is more loaded down with trivial details, also will relate to processes such as separation, purification, and expense is relatively more expensive.And the dissolubility of long-chain molecule is bad, the carrier surface self assembly relatively difficulty, be easy to bend and phenomenon such as turnover, coverage is low, is unfavorable for mobility of charge carrier.To further improve the mobility of charge carrier rate to improve the performance of device, just must be through controlling the performance that self-assembled structures that the thiophenes self assembly prepares high-sequential improves device.
Summary of the invention
In order to solve the defective that above technology exists; Can be dissolved in some organic solvent based on thiophenes; And can spontaneously be assembled under the theory of ordered structure at hydrophilic mica surface; Employing directly drips to the method for carrying out self assembly on the mica surface with thiophenes solution, and preparation has the oligo-thiophenes nanofiber of helical structure.The objective of the invention is to find a kind of method for preparing oligo-thiophenes nanofiber by achiral oligo-thiophenes molecule with helical structure.
Step of the present invention is following:
1) take by weighing 2.0mg oligo-thiophenes molecule and be dissolved in 2.0mL chloroform, 2.0mL oxolane or the 2.0mL benzole soln, vibration is prepared into oligo-thiophenes solution, because thiophenes solubility is little, solution is near saturated;
2) leave standstill 4h after, get its supernatant 20.0 μ L and drop in new explanation on the mica surface, put into drier 12h;
The mica that 3) will be adsorbed with the oligo-thiophenes molecule is put into baking oven, and dry 2-3h under 105 ℃ thoroughly volatilizees solvent, and the oligo-thiophenes molecule is self-assembled into the oligo-thiophenes nanofiber with helical structure through hydrophobic interaction.
The solvent of said dissolving oligo-thiophenes molecule is chloroform, oxolane or benzene.
Said oligo-thiophenes molecule is α-six polythiophene molecule, α-four polythiophene molecule and α-three polythiophene molecule.
Said substrate is a mica.
New explanation is meant the fresh mica of peeling off out from mica.
The oligo-thiophenes nanofiber with helical structure that this method makes characterizes through AFM and finds; Achiral oligo-thiophenes molecule is self-assembled into the oligo-thiophenes nanofiber with helical structure through hydrophobic interaction; The about 40-56 nanometer of the pitch of nanofiber, length from tens microns to the hundreds of micron.The oligo-thiophenes molecular agglomerate that has only a little.This kind preparation method is not only simple to operate, and the utilance of thiophene molecule is high.The more important thing is, prepared oligo-thiophenes nanofiber by achiral oligo-thiophenes molecule with helical structure.
