C—H⃛π interactions in 9‐(n‐do­decylamino­methyl)­anthracene

The title compound, C₂₇H₃₇N, which is intended to be included in the structure of a sulfon­amide porphyrin for the preparation of Langmuir–Blodgett films, consists of a do­decyl chain linked to an anthracene mol­ecule through an amino­methyl group. The angle between the least‐squares plane of the anthracene and the do­decyl chain is 11.44 (8)°. The mol­ecules are arranged in zigzag layers head‐to‐head, with the hydro­carbon chains side‐by‐side. The structure is stabilized by C—H?π interactions, the strongest having an H?centroid distance of 2.63 Å.
