Infrared absorbing croconaine dyes: Synthesis and metal ion binding properties

Rekha, R A; Jyothish, K; Ramaiah, D (American Chemical Society, 2008)

Quinaldine-based croconaine dyes synthesized by the condensation reaction between croconic acid and the respective quinaldinium salts are described. These dyes exhibit absorption maximum in the infrared region (840-870 nm) ...
Novel semisquaraine regioisomers: isolation, divergent chemical reactivity and photophysical properties

Rekha, R A; Jyothish, K; Suresh, C H; Ramaiah, D (Royal Society of Chemistry, 2011)

A zwitterionic semisquaraine 1,3-regioisomer which exhibits distinct photophysical properties and chemical reactivity was isolated. Uniquely, this isomer has been identified as the reactive intermediate in the squaraine ...
Tuning photosensitized singlet oxygen generation efficiency of novel aza-BODIPY dyes

Adarsh, N; Rekha, R A; Ramaiah, D (American Chemical Society, 2010)

Novel aza-BODIPY derivatives substituted with heavy atoms such as bromine and iodine were synthesized, and their triplet and singlet oxygen generation efficiencies have been investigated. These derivatives showed absorption ...
