Synthesis and spectroscopic properties of a new 4-bora-3a,4a-diaza-s-indacene (BODIPY®) dye

New luminophors based on the binuclear helicates of d-METALS with BIS(DIPYRRIN)S

“…At the present time two main areas of influence on the fluorescence of dipyrrin luminophors are developed. The first using a new type of ligands with higher rigidity of molecules (N 2 O 2 -type [17][18][19][20][21] and N 3 -type [22]), and the second varies the nature of the complexing agent (d-and f-metals, [13,15,16,23] Ga(III) and…”

A 1,3,2-oxazaborolidine dimer derived from (S)-α,α-diphenylprolinol

“…Both B-O distances in (II) are identical to within the s.u. (Lang et al, 1997;Kim et al, 1999;Chi et al, 1999Chi et al, , 2001). The observed B2-N1 distance of 1.618 (3) Å falls into the range of typical B-N distances [1.591-1.649 Å].…”

Synthesis and spectroscopic properties of β,β′-dibenzo-3,5,8-triaryl-BODIPYs

“…600–800 nm) BODIPYs bearing functionalities for enhanced solubility and/or for conjugation to biomolecules. Strategies for achieving these goals include: (1) functionalization at the 3,5-positions with aryl, 7 styryl 7 a , e ,8 or arylethynyl 7 a , d , e ,9 substituents, (2) replacement of the bridging meso -carbon with a nitrogen to generate aza-BODIPYs, 10 (3) prevention of free rotation of BODIPY aryl substituents, 11 and (4) benzo-fusion to the β,β′-pyrrolic positions. 12–15 The combination of two or more of these strategies can lead to BODIPYs with near-IR absorptions/emissions and enhanced quantum yields.…”
