Catenanes are a new class of potentially interesting materials for application in photonics. Good optical quality thin films of a benzylic amide catenanes were obtained by vacuum evaporation. They exhibit a large transparency range with cut off at around 300 nm and a large refractive index. The propagation losses depend on the wavelength and ar of 2.8 dB/cm, 4.5 dB/cm and 30 dB/cm at 1314 nm, 1550 and 633 nm, respectively. At 633 nm the propagation losses are clearly due to the Raleigh scattering.

Abstract
Catenanes are a new class of potentially interesting materials for application in photonics. Good optical quality thin films of a benzylic amide catenanes were obtained by vacuum evaporation. They exhibit a large transparency range with cut off at around 300 nm and a large refractive index. The propagation losses depend on the wavelength and ar of 2.8 dB/cm, 4.5 dB/cm and 30 dB/cm at 1314 nm, 1550 and 633 nm, respectively. At 633 nm the propagation losses are clearly due to the Raleigh scattering.File in questo prodotto:
