Efficient UV polymerisation of 3BCMU: Optical and waveguiding properties of the material

A modified method to synthesize 3BCMU and to polymerize it by ultraviolet (UV) radiation is presented; the polymerization technique gave a maximum yield of 18%. Langmuir-Blodgett and spin coated films of UV/poly-3BCMU have been fabricated. Visible and resonance Raman spectroscopy and waveguide tests were performed: the results are compared with those obtained with y/poly-3BCMU films.
