In this paper we report the optical absorption and photoinduced absorption spectra of poly(1-N-carbazolyl-penta-1,3 diyne-5-acetoxy) and of poly(1-N-carbazolyl-penta-1,3-diyne-5-ol) and their relation to temperature, excitation intensity, and frequency of the pump-probe cycles. Preliminary data on an oligomeric sample are also discussed. All...

We report on the laser action in a microcavity where both the dielectric mirrors and the active material have a macromolecular nature, resulting in a full plastic laser device. Distributed Bragg reflectors (DBRs) are prepared by spincoating of polyvinylcarbazole and cellulose acetate orthogonal solutions and the active layer consists of a...

We report on the photoinduced absorption spectra of polycarbazolydiacetylenes po1yDCHD and its soluble analogous polyDCHD-S in a broad time domain ranging from femtosecond to millisecond. Both the blue and red forms of po1yDCHD-S are investigated and the results are compared with those of blue polyDCHD. In the blue form of the two polymers...
