This study demonstrates how simple structural modification of a prototypical organic ferroelectric molecule can be used to tune its key properties. In particular, it is found that shortening the alkyl chain length trialkylbenzene‐1,3,5‐tricarboxamide (BTA) from C 18 H 37 6 13 causes an increase in depolarization activation energy ( ≈ 1.1–1.55 eV), coercive field 25–40 V µm −1 ), and remnant polarization 20–70 mC m −2 ).
