| Details: | 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. This study describes which physical-organic rationale 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.[3] Photophysical properties are discussed by experimental and theoretical means. It is shown that the suprastructure of the oligomeric dyes plays a significant role for their absorption and emission properties. |
