Problems solved by technology

However, since the absorption wavelength range and light absorption characteristics of light are limited, the development of organic conjugated polymers with high absorbance in a wide wavelength range and excellent photoelectric conversion efficiency is required for applications such as organic solar cells.
In addition, since the emission wavelength range of the conjugated polymer is limited, its application as an electronic device is limited.

Embodiment 1

[0206] [chemical formula 20]

[0207]

[0208] (In the formula, R represents 2-ethylhexyl, and x and y represent the content ratio (molar ratio) of each structural unit, which is x:y=0.44:0.56.)

[0209] Under an argon atmosphere, 1,4-diethynyl-2,5-bis(2-ethylhexyloxy)benzene (0.191g, 0.500mmol) and tetraisopropoxytitanium (Ti(OPr i ) 4 ) (0.198g, 0.700mmol) was dissolved in cyclopentyl methyl ether (20ml), and while the solution was stirred at -78°C, isopropylmagnesium chloride was further added ( i PrMgCl) in diethyl ether (1.0 N, 1.25 ml, 1.25 mmol). Thereafter, the temperature was slowly raised to -50°C and stirred for 12 hours. At this temperature, dichlorophenylphosphine (0.053 g, 0.300 mmol) and disulfur dichloride (0.041 g, 0.300 mmol) were added step by step, Slowly warm to room temperature and further stir for 12 hours. Water was added to the obtained reaction solution, extracted with chloroform, and reprecipitated with hexane to obtain a red polymer represented...

Embodiment 2

[0229] On FTO glass (manufactured by Astellatech Co., Ltd., model FTB) cleaned with acetone, a titanium oxide paste ("Ti-Nanoxide T / SP" manufactured by SOLARONIX Co., Ltd.) was formed into a 4 mm film with a thickness of 10 μm by the screen printing method The square was dried at 100° C. using a hot plate, and then baked at 500° C. for 1 hour to obtain a titanium oxide electrode.

[0230] The polymer obtained in Example 1 was dissolved in THF to prepare a 0.1% by weight solution. The aforementioned titanium oxide electrode was immersed in the solution, and left to stand at room temperature for 24 hours to allow the polymer obtained in Example 1 to be adsorbed on the surface of titanium oxide. After the adsorption, the titanium oxide electrode was taken out from the solution, washed with THF and dried to obtain a polymer-adsorbed titanium oxide electrode. As the counter electrode of this polymer-adsorbed titanium oxide electrode, a platinum thin film (thickness 0.003 μm) was f...

Abstract

This organic heteropolymer is useful in forming organic semiconductors and is a copolymeric heteropolymer that comprises a structural unit represented by formula (1) and a structural unit represented by formula (2). (In the formulas: M1 and M2 represent heteroatoms selected from mutually differing groups among the group 8 elements, the group 9 elements, the group 10 elements, the group 14 elements, the group 15 elements, and the group 16 elements on the periodic table; the atomic valence (v) of M1 and M2 is in the range 2-6; R1a and R1b each represent a halogen atom, an alkyl group, a cycloalkyl group, an aryl group, or a heteroaryl group and may be the same or different; R2a and R2b each represent a halogen atom, an alkyl group, a cycloalkyl group, an aryl group, a heteroaryl group, a monovalent or bivalent heteroatom selected from the group consisting of the group 16 elements and the group 11 elements on the periodic table, or a metal atom that has formed a complex with a ligand and may be the same or different; m1, m2, n1, and n2 each represent 0 or 1; circled Ar represents an aromatic ring; R3 represents a straight-chain or branched-chain alkyl group, a straight-chain or branched-chain alkoxy group, or a straight-chain or branched-chain alkylthio group; and p represents 0 or an integer in the range 1-3.)

Description

technical field [0001] The present invention relates to an organic heteropolymer containing different kinds of heterocycles, such as an organic semiconductor or a sensitizer (sensitizer), which can be used in electronic devices such as semiconductor elements and photoelectric conversion elements, and a method for producing the same. Background technique [0002] Most organometallic compounds represented by metallophthalocyanines form specific electronic states or very stable molecular structures through the bonding between organic molecules and metals. Based on these characteristics, it has been used as an organic pigment etc. until now. [0003] In recent years, due to their responsiveness to external energy such as heat, light, or electric field, the application of organometallic compounds has been expanded to electronic fields such as photosensitive materials for electrophotographic printers and recording media such as CD-R. In particular, recently, its function as an or...
