Provided is an electron-accepting substance precursor comprising a sulfonic acid ester compound represented by formula (1).
(In the formula, R1-R4 each independently represent a hydrogen atom, or a straight-chain or branched C1-6 alkyl group. R5 represents a C2-20 monovalent hydrocarbon group which may be substituted. A1 represents —O— or —S—. A2 represents a group having a valence of (n+1) and derived from naphthalene or anthracene. A3 represents a group having a valence of m and derived from perfluorinated biphenyl. m represents an integer satisfying 2≤m≤4. n represents an integer satisfying 1≤n≤4).
提供的是一种电子受体物质前体,其包括由公式(1)表示的
磺酸酯化合物。(在公式中,R1-R4各自独立地表示氢原子或直链或支链C1-6烷基。R5表示可以被取代的C2-20单价碳氢基团。A1表示-O-或-S-。A2表示一个由
萘或
蒽衍生的具有(n+1)价的基团。A3表示一个由
全氟联苯衍生的具有m价的基团。m表示一个满足2≤m≤4的整数。n表示一个满足1≤n≤4的整数。)
