摘要：

The flower pigment cyanidin anchors into nanoporous films of TiO2 by surface complexation. A photoelectrochemical cell made from cyanidin-sensitized nanoporous TiO2, as a film deposited on conducting glass and with the I- + I-3(-) redox couple in acetonitrile, generates high photocurrents of good stability.
