"Design of dye-like compounds for potential optoelectronic applications"

Nowadays, dye-like and --conjugated organic compounds represent attractive targets for diverse application in advanced functional materials. (1) Organic --systems end-capped with an electron donor (D) and an electron acceptor (A) represent a subclass of these kinds of molecules, widely known as push-pull systems. They have predominant applications as chromophores with nonlinear optical (NLO) properties, electro-optic, and piezochromic materials, NLO switches, photochromic, charge-based information storage and solvatochromic probes as well as active layers in DSSCs. In this sense, the research on exploring novel efficient sensitizers, based on the donor-- bridge-acceptor (D’A) configuration is mainstream in the design of organic sensitizers due to its convenient modulation of the intramolecular charge-transfer nature.

In this context, we have focused our efforts in the synthesis and study of the molecular absorption, energy levels and voltammetry behavior of a series of novel push-pull dyes, containing different structural motifs. For instance, azo-pyrrole(2) and ferrocenyl amphiphilic(3) dyes have demonstrated promising results that prompt us to explore their use as sensitizer or as photoswitches that can be activated using biphotonic techniques.
