1. A composition for an electronic device consisting of a component A, a component B, and optionally a component C which is a solvent or a solute, wherein the component A is a fluorine-containing solvent, and the component B is a compound having a structure represented by the following Formula (1),

OG Complex Work Unit Chemistry
wherein X1 to X9 each independently represent —CWm or a nitrogen atom, m of —CWm represents 1 to 9, and the substituents —CW1 to —CW9 correspond to X1 to X9, respectively; W1 to W9 each independently represent a hydrogen atom or a substituent; when L1 and L2 are not linked to each other, L1 and L2 each independently represent a hydrogen atom or a substituent Wm1, m of Wm1 represents 1 or 2, the substituents W11 and W21 correspond to L1 and L2, respectively; L1 and L2 may be linked to each other, in which case L1 and L2 are linked to each other via any one atom of oxygen, sulfur, carbon and nitrogen to form a 6-membered ring; in the case of a carbon atom, it represents CS1S2; in the case of a nitrogen atom, it represents NR1; L3 and L4 each independently represent an oxygen atom, a sulfur atom, —CSn1Sn2, or —NRn3, n represents 3 or 4, —CS31S32 or —NR33 corresponds to L3, and —CS41S42 or —NR43 corresponds to L4; and S1, S2, S31, S32, S41, S42, R1, R33, R43, W11 and W12 each independently represent a substituent, and
in a case where the component C is present in the composition, a Hansen solubility parameter distance (Ra2) between the component A and the component B is longer than a Hansen solubility parameter distance (Ra1) between all solvents in the composition for an electronic device and all solutes in the composition for an electronic device.
