| Abstract: | Carbazoles react with a variety of one-carbon fragments at the 3- or 3,6-positions to give di- and trimeric products with CH2: links. These precursors react by losing hydride ion to give blue oligomeric dyes. Carbazoles substituted in the 9-position by CH2SPh, CH2SOPh, and CH2SO2Ph rearrange to give carbazole oligomers linked at the 3,6-positions. Products are characterised spectrally, and their mechanism of formation is discussed. |
