Title:
COMPOSITION FOR HOLE COLLECTING LAYER OF ORGANIC PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/110317
Kind Code:
A1
Abstract:
This composition for a hole collecting layer of an organic photoelectric conversion element contains: a charge-transporting substance comprising a polyaniline derivative represented by formula (1); a fluorine-based surfactant; and a solvent. The composition provides a thin film suitable for a hole collecting layer of an organic photoelectric conversion element, and is particularly suited for producing an inverse lamination type organic photoelectric conversion element. (In the formula, R1 to R6 each independently represent a hydrogen atom, etc., but one of R1 to R4 is a sulfonic acid group, one or more of the remaining R1 to R4 are a C1-20 alkoxy group, a C1-20 thioalkoxy group, a C1-20 alkyl group, a C2-20 alkenyl group, a C2-20 alkynyl group, a C1-20 haloalkyl group, a C6-20 aryl group, or a C7-20 aralkyl group, and m and n are numbers which satisfy 0≦m≦1, 0≦n≦1 and m+n=1.)
