## Abstract We measured photoinduced refractive index changes (see Figure) of polymer films containing various sulfurβcontaining mesoionic compounds. PMMA films containing 30 wt.β% of 3βphenylβ1,2,3,4βthiatriazoleβ5βthione (3PTTT) showed refractive index changes of β0.036 during photoirradiation, a
