ESR measurements were performed on Langmuir-Blodgett (LB) films of 1:2 complex of long-chain pyridinium and TCNQ, where the long chain contains photo-active azobenzene group. Observed temperature dependence of the spin susceptibility is consistent with the formation of the random-exchange Heisenberg antiferromagnetic chains in the system.
