Intramolecular charge-transfer interactions in a julolidine-Bodipy molecular assembly as revealed via 13C NMR chemical shifts
Benniston, Andrew C.,Clift, Sophie,Harriman, Anthony
, p. 346 - 354 (2011)
13C NMR spectra were recorded in a series of six deuterated solvents of disparate polarity for three difluoroborondipyrromethene (Bodipy) derivatives bearing an aryl group at the meso position; these aryl residues were julolidine (JULBD), 4-nit

Regioselective halogenation is often a key step in the formation of substituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) fluorophores, through the enablement of subsequent downstream C–C or C-X bond forming steps via SNAr or metal ca

Although ultra-large optical asymmetry appears in crystalline materials, distractions from the mesoscopic ordering often causes inauthenticity in chiropticity. In amorphous materials, however, it remains challenging and elusive to achieve large chiropticity. Herein, we report the quantitative control of chiral amplification, on amorphous supramolecular structures of cholesteryl-linked bis(dipyrrinato)zinc(II), to an exceptionally high level. A proper chiral packing of the building block at several molecular scale considerably contributes to the absorptive dissymmetry factor gabs, although the system is overall disordered. The intense and tunable aggregation strength renders a variable gabs value up to +0.10 and +0.31 in the solution and in film state. On this basis, a superior ON-OFF switching of chiropticity is realized under external stimuli. This work establishes a general design principle to control over ultra-large optical asymmetry on a wider scope of chiral materials.

Formylation has been performed on pyrrole-unsubstituted dipyrromethanes 1 and boron-dipyrrin (BODIPY) dyes 4 based on a Vilsmeier-Haack reaction. It is highly regioselective and complementary and occurs exclusively at the α-and β-position, respectively, f
