Design and Serendipity in Fluorophore Chemistry

The rich chemistry of the BODIPY motif, together with its beneficial photophysical properties, has markedly
boosted the popularity of this user-friendly fluorophore over the last few decades.
[1] The diversity of easily
incorporated fluorescence modulation modes has set the stage for a variety of sensorically active species.
The talk describes which physical-organic rationalisation led to the development of the BOIMPY motif
showing a significant red-shift with respect to the parent BODIPY.
[2] In addition, a simple synthetic route to
oligomerized ethano-linked BODIPYs (up to an octamer) is presented which can be further oxidized to huge
completely conjugated systems.
[3] Photophysical properties and biological properties are discussed by
experimental and theoretical means.[4] It is shown that the suprastructure of the oligomeric dyes plays a
significant role for their absorption and emission properties and that the conjugated systems are interesting
NIR fluorophores.
