Pillararene complex

Abstract

An object of the present disclosure is to provide a composite having excellent heat resistance and/or hydrophobicity and allowing easy introduction of a functional group thereinto. A composite comprising: a polymer; and one or more cyclic compounds that include the polymer, where the cyclic compound comprises a compound represented by the following formula (I): where A independently represents a divalent C4-50 organic group comprising one or more selected from —OR and —CO—, R independently represents an organic group optionally comprising one or more fluorine atoms, or a hydrogen atom, and n represents an integer of 4 to 20, and one of the polymer and the cyclic compound comprises one or more selected from —CO—, a nitrogen atom, and a halogen atom, and the other has a group comprising a hydrogen atom capable of interacting with —CO—, the nitrogen atom, or the halogen atom.

Dependencies are inferred from the claim text.
