Solvatochromy and electro-optical study of new fluorine-containing chromophores

subject

description

technology requires tailored functional materials which fulfill the demands for optimal operation parameters, reliability andprocessability. Organic chromophores and polymers which contain covalently bound chromophores are promising materialclasses which can satisfy a broad spectrum of demands on functional materials for photonics, and they are, therefore,favorites for the development of new photonic devices. However, it is almost impossible to satisfy all physico-chemical andtechnological requirements simultaneously with a polymer consisting of only one type of functional unit. The developmentof a series of different building blocks which allow to cover the whole range of physico-chemical parameters necessary fordifferent photonic device applications is, therefore, a big challenge to recent research efforts in chemistry, physics andengineering. The present study is devoted to new chromophores which should mainly be used to define nonlinear opticalproperties but which also can tune linear optical properties of functional polymers for photonic applications.Linear and nonlinear optical properties of NLO-chromophores depend both on topological features of the active rr-electronsystem like its planarity, length or dimensionality as well as on the chemical nature of substituents modifying the wavefunctions of those molecular states which are mainly contributing to the linear and nonlinear optical polarizabilities.Part of the
