A novel processable polycarbazolyldiacetylene has been prepared, which allows to obtain homogeneous films very promising for waveguiding devices. The electronic spectra of the polymer in different solvents are discussed and preliminary data on the linear optical characterization of the films are reported. It is shown that at 849 nm the visible guided streak is only a few millimeters long, while at 1321 nm it reaches the film end (about 2.5 cm).
