Abstract : A new class of materials; optically clear, non-birefringent phthalocyanine glasses and their thin film nonlinear optical properties are described. This synthetic approach consists of introducing functionality at the phthalocyanine ring periphery with a design for hydrogen bonding, stereochemical interaction, and irregular symmetry to promote glass formation by inhibiting molecular organization. Additionally, the peripheral functionality depresses the glass transition temperature to a practical processing range. The thin film nonlinear optical properties of these materials exhibit excited state absorption characteristics which give rise to a nonlinear optical response potentially useful for optical limiting.
