Chromophores [1] with light absorption at long wavelengths in the visible or even in the near infrared are becoming increasingly attractive [2]. Commonly, such a bathochromic absorption is realized with very large π systems; see for example ref. [3]. Bathochromically absorbing smaller molecules are more difficult to obtain [4], but can be developed by balancing substituent effects in conjugated...

A white-rot fungus, strain SQ01, was isolated from decayed wood in a temperate forest. The strain was identified as a member of genus Trametes, based on the morphological characteristics and a complete sequence analysis of its 18S rRNA gene and ITS region. Strain SQ01 was capable of decolorizing a variety of synthetic dyes, including azo, triphenylmethane, and anthraquinone dyes, with an optima...

Extensive dependence of textile and other industries on the synthetic dyes have made these chemicals a necessary evil nowadays. Among all classes dyes, triphenylmethane (TPMs) are most common unfortunately hazardous. The wastewater originated from various is usually found to contain major portion TPMs along-with inorganic organic contaminant which lead serious environmental consequences. In thi...

27 The enzyme triphenylmethane reductase (TMR) reduces toxic triphenylmethane dyes into 28 colorless, non-toxic derivatives, and TMR-producing microorganisms have been proposed as 29 bioremediation tools. Analysis of the genome of Listeria monocytogenes H7858 (1998-1999 hot 30 dog outbreak) revealed that the plasmid (pLM80) of this strain harboring a gene cassette 31 (bcrABC) conferring resista...

Amongst functional macromolecules, the combination of polymers and dyes is a research field of great potential with regard to high-performance materials. Accordingly, colored polymers have become increasingly important as materials for miscellaneous technical applications in recent years while also being a major part of everyday life. For instance, dye-containing polymers are nowadays widely ap...

The D3h symmetric tris(dialkylamino)trioxatriangulenium ((R2N)3TOTA+) ions are structurally related to classical stains and fluorophores such as triphenylmethane dyes and rhodamines. New derivatives of (R2N)3TOTA+, in which long flexible alkyl chains surround the planar and rigid aromatic core, have been synthesized and isolated as hexafluorophosphate salts. In contrast to short-chain derivativ...
