Abstract

A new ferroelastic organic salt nicotinic acid bromide (N–Br) was connected by hydrogen bonding with nicotinic acid cations via a halogen substitution strategy. It exhibits a ferroelastic phase transition from P2₁/m to P [1 with combining macron] with 2/mF Aizu notation with a high Curie temperature (T_c) of 402 K. Moreover, optical regulation from blue light to white light was achieved by halogen substitution.
