N-Heterocyclic Carbene Organic Dyes Derived from 2,4,5,6-tetra(9H-Carbazol-9-yl)isophthalonitrile (4CzIPN) Bonded to TiO 2 Surfaces

A high-yield route to N-heterocyclic carbene (NHC) derivatives of 2,4,5,6-tetra(9 H -carbazol-9-yl)benzene-1,3-dicarbonitrile (4CzIPN) is reported. The NHC-dye was studied in solution by NMR, infrared- and UV–vis spectroscopy, cyclic voltammetry, and photoluminescence. The NHC group bonds to the sur...

Summary:A high-yield route to N-heterocyclic carbene (NHC) derivatives of 2,4,5,6-tetra(9 H -carbazol-9-yl)benzene-1,3-dicarbonitrile (4CzIPN) is reported. The NHC-dye was studied in solution by NMR, infrared- and UV–vis spectroscopy, cyclic voltammetry, and photoluminescence. The NHC group bonds to the surface of TiO 2 forming a semiconductor/chromophore system that was characterized by cyclic voltammetry, XPS, infrared and UV–vis spectroscopy as well as photoluminescence. The bonding between the NHC group and TiO 2 is quite stable towards the photooxidation of sacrificial electron donors under alkaline conditions without applying any protective layers.
