Increasingly popular due to their competitive optical properties like

1, 2 BODIPY dyes and their derivatives have become For several biological assays or screeningĮxperiments as well as in fluorescence microscopy, just to name anĮxample, dyes with near-infrared absorption and emission are preferableĭue to less interference from autofluorescence and a larger penetrationĭepth. Is the foundation for successfully tuning molecular properties toįit specific applications. Of tailor-made molecules for future applications. Of the structure–optics relationship of the (aza)-BODIPY-dyeĬlass, leading to an improvement in the de novo design The outlook of this study is a deeper understanding This result could be evident in a substitution pattern-dependent The effect of electron-donating units on theĪbsorption but not emission for BODIPYs was suppressed compared toĪza-BODIPYs. Transition and considerably different, temperature-activated, excited-state Replacing the meso-methine bridge with an aza-N bridge results in a red-shifted Sets is the bridging unit providing a so far lacking comparison betweenīODIPYs and aza-BODIPYs structural homologues. Substituents were condensed together in two different manners, thus

Using combinatorial chemistry, pyrroles substituted with electron-donating/-withdrawing This workĭelivers a photophysical evaluation of BODIPY and aza-BODIPY derivativesĮquipped with different electron-withdrawing/-donating substituents. Understanding based on experimental observations is vital. Molecules specifically for one’s needs, a solid structure–function Properties prior to synthesis and therefore to successfully design (BODIPY) have a highly respected position.
