Manufacture of functional tetrahydroquinoline dye containing thiophene bridge bonds.
2006 (English)Patent (Other (popular science, discussion, etc.))
Abstract [en]

The title dye employs 1,2,3,4- tetrahydroquinoline and its derivates as the electron donor and a different no. of thiophene units with adjustable absorption spectrum and fluorescence emission spectrum as the bridge bonds to connect different electron-absorption groups. The dye can be expressed by a general formula I, wherein R1 is C1-C20 linear alkyl or branched alkyl; R2 is H, or C1-C3 linear alkyl or branched alkyl; R3 is H or methyl; R4 is H, C1-C20 linear alkyl or branched alkyl, amido, alkoxy or halogen; R5 is PO(OR')2, -COOR', -SO2OR' or CN, wherein R' is H, or C1-C30 linear alkyl or branched alkyl; m=0 or 1; n=1-6. Tetrahydroquinoline as a chromophore has a good electron supply capability. Thiophene units connected with different electron-absorption groups have high electron-cloud d. and particular optical characteristics and electron transmission capability. The dye has the advantages of high optical stability, high thermal stability, high chem. stability and good photoelec. character, and can be used for dye sensitized nanocrystaline solar batteries and photoluminescent or electroluminescent testing kits.
