Abstract

The photoinduced optical retardation in mesostructured polymeric materials containing photo-orientable dyes has been investigated as a function of time and pump irradiance by an imaging pump-probe technique. The mesostructured samples show higher maximum retardation and lower residual anisotropy than amorphous ones. Several hypotheses are made to explain both results, taking into account the influence of the mesostructures on the chromophores. The retardation-irradiance curves measured in different samples are fitted against current available models.

Fig. 1

IPP optical setup. Polarizers (P1 and P3) and half-wave plates (W1 and W2) for 632.8 and 543 nm are used to set the proper polarization of the probe and the pump beams. The probe beam passes through a beam expander with spatial filter (B). S, sample; F, long pass optical filter; P2, analyzer; D, diffuser screen; L, imaging lens; C, CCD camera. Inset, the bright circular region in the image (plot of level curves) is due to a PIB spot written in the sample A1.

Absorption spectra of the samples in the visible range. Left, DR1-based samples; inset, DR1 molecule. Right; DO3-based samples; inset, DO3 molecule. The flatness of the absorption band of samples A3 and B3 is not due to instrumental saturation.
