containing analogues as well as an unsubstituted BODIPY derivative. The fluorescence quantum yields were found to decrease, whereas the intersystem crossing quantum yields (PhiISC), determined by transientspectroscopy, increased in the order of the H --> Cl --> Se/I --> Te substitution. The maximum PhiISC, found for the 3-phenyltellanyl derivative, was 59%. The results are interpreted in terms of the internal
合成了三种单取代的3-苯基硒基和3-苯基tellanyl BODIPY衍生物,并对它们的光谱性质进行了表征,并与含有类似物以及未取代的BODIPY衍生物的碘和氯原子的光谱性质进行了比较。发现荧光量子产率降低,而通过瞬态光谱法测定的系统间交叉量子产率(PhiISC)按H-> Cl-> Se / I-> Te取代的顺序增加。对于3-苯基碲烷基衍生物,发现最大的PhiISC为59%。根据取代基的内部重原子效应来解释结果。

Endowing BODIPY PDT agents with the ability to probe lipid droplets is demonstrated to boost their phototoxicity, allowing the efficient use of highly fluorescent dyes (poor ROS sensitizers) as phototoxic agents. Conversely, this fact opens the way to the development of highly bright ROS photosensitizers for performing photodynamic theragnosis (fluorescence bioimaging and photodynamictherapy) from a

development of fluorescent inhibitors addressing the GABA transporters mGAT1–mGAT4 as potential tool compounds in fluorescence based biological assays. The design of these fluorescent GAT inhibitors followed the structural motifs common for many GAT1–GAT4 inhibitors publicly known except that the lipophilic domain present in this compounds was replaced by a BODIPY moiety to serve as a fluorescent subunit

A careful choice of the pyrrole building blocks allows the synthesis of a wide range of monohalogenated BODIPY dyes with excellent reactivity in palladium catalyzed coupling reactions.
developing one. We have designed a BODIPY‐based probe called (S)‐Sulfox‐1, which is equipped with a reactive sulfoxide moiety. Upon reduction with a model MsrA (E. coli), it exhibits a bathochromic shift in the fluorescence maximum. This feature was utilized for the real‐time ratiometricfluorescentimaging of MsrA activity in E. coli cells. Significantly, our probe is capable of capturing natural variations
