Popis:	Three polymethine dyes of various structures were checked for their potential to be used as sensitising dyes for TiO 2. Based on the absorption spectral data and cyclic voltammetric redox potential, the lower unoccupied molecular orbital (LUMO) energy was calculated. It was higher than the conductance band edge energy of anatase TiO 2 for all the studied dyes, meaning that they all may act as efficient sensitizers for various functional materials to be used in the broad spectrum visible-light solar cells, energy conversion systems and other similar applications.
