H NMR spectral evidence for a specific host-guest complexation induced charge localization in squaraine dyes

Ajayaghosh, A; Arunkumar, E (American Chemical Society, 2005)

Experimental support is provided for the charge localization in squaraines, a class of fundamentally and technologically important organic dyes, by H-1 NMR analysis through a host-guest complexation approach. Specific ...
Proton controlled intramolecular photoinduced electron transfer (PET) in podand linked squaraine-aniline dyads

Arunkumar, E; Ajayaghosh, A (Royal Society of Chemistry, 2005)

Proton controlled intramolecular PET from an aniline moiety to a squaraine chromophore, attached to podand chains is reported, which to our knowledge is the first example where a squaraine dye is involved as an electron ...
Selective calcium ion sensing with a bichromophoric squaraine foldamer

Arunkumar, E; Ajayaghosh, A; Daub, J (American Chemical Society, 2005)

Several squaraine tethered bichromophoric podand systems 1a-d and a monochromophoric analogue 2 were prepared and characterized. Among these, the bichromophore, 1b, containing five oxygen atoms in the flexible podand moiety ...
