摘要： The present invention provides an organic photoelectric conversion material such that an increase in the solution viscosity can be suppressed even after long-term storage. This organic photoelectric conversion material comprises Pd, wherein the average number of Pd clusters in a scanning transmission electron microscopic image of a thin film made of the organic photoelectric conversion material is 1500 counts/µm 3 or less. It is preferable that the Pd clusters each have a particle diameter of from 1 nm to 20 nm. It is preferable that the organic photoelectric conversion material is a polymer for organic photoelectric conversion material; and it is more preferable that the polymer for organic photoelectric conversion material is a D-A type π-conjugated polymer. It is preferable that the polymer for organic photoelectric conversion material has a thiophene ring.

摘要： Provided is a method for producing a π-conjugated polymer capable of suppressing an increase in dark current of an organic photoelectric conversion element even if the method includes a purification step including heating. A method for producing a π-conjugated polymer includes: step (I) of heating and dissolving a crude π-conjugated polymer in a solvent to obtain a polymer solution; and step (II) of precipitating a π-conjugated polymer from the polymer solution. In step (I), the content of peroxide in the solvent is 0.1% or less in terms of a relative area ratio measured by high-performance liquid chromatography, and the electron spin concentration of the π-conjugated polymer is 30 × 10 16 Spin/g or less and/or 2.5 times or less the electron spin concentration of the crude π-conjugated polymer.
