Thermoresponsive fluorescent polymers based on a quaterthiophene-containing boron dipyrromethene (Bodipy) dyad dispersed in silicone rubber

Solution processable diketopyrrolopyrrole (DPP) cored small molecules with BODIPY end groups as novel donors for organic solar cells

“…Both triads 9 and 10 show absorption maxima at 542 nm, which is ascribed to the absorption of the BODIPY units. Interestingly, the absorption peak of BODIPY in these compounds is exactly the same value found for a series of BODIPY unit derivatives substituted with oligothiophenes at the meso -position [ 47 ]. Thus, the incorporation of two extra thiophene rings, and connection to the DPP core, does not affect the absorption peak associated with the BODIPY units.…”

“…The synthesis of 7 was achieved from the α-brominated derivative of bithiophene carbaldehyde 4 . This synthetic route to prepare 7 has been described previously in the literature [ 47 ]. Formylation of the bithiophene was carried out using Vilsmeier–Haack conditions by treatment with phosphoryl chloride and N,N -dimethylformamide to give 3 , which in turn was brominated with NBS (1.05 equiv) to yield compound 4 .…”

“…Compound 7 was prepared following the same procedure used to synthesise 6 . Whereas the synthesis of 6 was achieved in 33% yield, the yield decreased to 12% when the derivative with two thiophenes was prepared [ 47 ].…”

The inorganic DMSO/POCl3 reaction with BODIPY: wide product formation and implications for biological ROS sensing and neurodegenerative disease research

“…Heteroatom diversity has extended to the 8-aryl group: 8-furyl and 8-thienyl systems were first reported in 2007 [4,5]. 8-position multithienyl conjugates [6][7][8][9], aniline-containing extensions [10,11], and fluorophore extensions have also led to BODIPY versatility [12]. Reports of 3-thienyl [4,[13][14][15][16]] and 3-furyl groups are fewer [13].…”

A Solution‐Processable meso‐Phenyl‐BODIPY‐Based n‐Channel Semiconductor with Enhanced Fluorescence Emission

“…[10][11][12][13] Among various π-building blocks, 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) has recently attracted attention in the design of molecular semi-conductors for optoelectronics. [14] In the past few decades, BODIPY-based small molecules have been studied as fluorescent switches/sensors, chemosensors, biochemical labels, and photodynamic therapy agents, [15][16][17][18] and they have shown remarkable photophysical properties such as high fluorescence quantum yield, large extinction coefficient, small Stokes shifts, high photostability, and tunable absorption/fluorescence profiles. [19] The recent optoelectronic applications of BODIPY πsystems include organic photovoltaics (OPVs), [20] dye-sensitized solar cells (DSSCs), [21] organic field-effect transistors (OFETs), [22] light harvesting, [23] and near-infrared absorption.…”
