Abstract

Recently organic and polymeric materials have shown considerable promise for the development of nonlinear optical devices.¹ Of particular interest for waveguide and bistable device applications is the construction of molecules which exhibit large values of χ⁽³⁾, a fast response to applied optical fields, and photochemical stability, Fluoroaluminum phthalocyanine (AIPc-F), which contains a 2-D π-electron system, has shown a relatively large optical nonlinearity [χ⁽³⁾ = 5 × 10⁻¹¹ esu] and very high laser damage threshold (>20 GW/cm²), The measurement of the electronic dynamics of polycrystalline AIPc-F at room temperature is reported.
