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

Nowadays, dye-like and π-conjugated organic compounds represent attractive targets for diverse application in advanced functional materials. (1) Organic π-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–π bridge–acceptor (D–π–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.
