Abstract
A novel dual functional biindenylidene derivative (4) having nitronyl nitroxide radicals on both sides of the molecules, was synthesised. Its photochromism, as well as magnetic properties were investigated. The compound 4 underwent photochromic reactions by irradiation with UV and visible light. The intermolecular magnetic interactions were measured with a SQUID susceptometer.
