F. Saremi et al., DEEPLY COLORED SELF-ASSEMBLED MULTILAYERS OF ANIONIC DPP BOLAAMPHIPHILES AND CATIONIC POLYELECTROLYTES, Advanced materials, 8(11), 1996, pp. 923
Self-assembled ultrathin multilayer films containing DPP or DTPP chrom
ophores are reported. The preparation of the multilayers built up out
of a DPP derivative and a cationic polyelectrolyte on a silanized glas
s slide is described (see Figure), followed by the characterization of
their optical properties. The stability of the deep red (DPP) or yell
ow (DTPP) films makes them particularly suitable for technical applica
tions.
