Die vielseitige Chemie von Bodipy‐Fluoreszenzfarbstoffen

Abstract

Organische Luminophore wurden lange nur in biologischen Markierungsverfahren und bestimmten analytischen Nachweisen angewendet, doch in jüngster Zeit werden auch neuartige organische elektronische Materialien und Farbstoffe für die aufstrebende Nanotechnologie entwickelt. Unter vielen verschiedenartigen Fluoreszenzfarbstoffen erwiesen sich dabei die Bodipy‐Farbstoffe, die zunächst als Lumineszenzmarker und Laserfarbstoffe entwickelt worden waren, als besonders geeignet. Dieser “kleinen Schwester des Porphyrins” scheinen große Perspektiven offenzustehen.

Visible‐Light‐Harvesting Triphenylamine Ethynyl C60‐BODIPY Dyads as Heavy‐Atom‐Free Organic Triplet Photosensitizers for Triplet‐Triplet Annihilation Upconversion

“…[45][46][47] Nonsubstituted BODIPY absorbs at approximately 500 nm. To access longer absorption wavelengths, a triphenylamine moiety was linked to the BODIPY unit through an ethynylene bond (C C, dyads C-1 and C-2, Scheme 1 and Scheme 2).…”

Strongly Emissive and Photostable Four‐Coordinate Organoboron N,C Chelates and Their Use in Fluorescence Microscopy

“…In this aspect the herein investigated dyes overcome the often for Bodipy dyes observed small Stokes shifts (ca. 500-1000 cm -1 ) [10,11] which cause problems such as the re-absorption of emitted photons, homo-energy transfer or the undesired detection of strayed excitation light. These shortcomings normally require alternative photophysical designs such as antenna-Bodipy energy transfer dyads.…”

“…[1][2][3][4] The structural scope includes N,O-and N,Nchelates with five-and six-membered rings as most common binding motifs [3,5] as well as bi-nuclear boron complexes. [6] Prominent examples are boron 8-hydroxyquinolinate complexes, [7,8] boron dipyrromethene (Bodipy) dyes, [9][10][11] boranils, [12,13] and boron iminocoumarins (Boricos). [14] To a lesser extent organoboron complexes with N,C-chelate systems were reported, [15][16][17][18][19] B(ppy)Mes2 compounds (ppy = 2-phenylpyridyl, Mes = mesityl) being an example.…”

Novel Molecular Building Blocks Based on the Boradiazaindacene Chromophore: Applications in Fluorescent Metallosupramolecular Coordination Polymers

“…[20][21][22][23] In recent years, there has been a flurry of activity investigating many derivatives and numerous applications of these dyes. Among these, fluorescent chemosensors, [24][25][26][27] molecular logic gates, [28] fluorescent organogels, [29] sensitizers in dye-sensitized solar cells, [30,31] cellular imaging, [32] and applications in photodynamic therapy [33,34] are particularly noteworthy.…”
