Abstract

The semi-intercalation of an azo-dye Disperse Red 1 (DR1) molecule into a biopolymeric material made of deoxyribonucleic acid (DNA) complexed with the cationic surfactant hexadecyltrimethyl-ammonium chloride (CTMA) formulated recently^1-3 has successfully explained the main experimental results⁴ of laser dynamic inscription of diffraction gratings: short response time, low diffraction efficiency, single-exponential kinetics and flat wavelength dependence.5 In this paper we generalize the analytic model of Ref.² to account for a more realistic dynamics of DNA-CTMA matrix. To this end we extend the model of paper⁵ by including into it probabilistic features of local free volume in DNA matrix which characterize, in a simple way, the spatial distribution of local voids which, in turn play the central role for the kinetics of photoinduced trans-cis-trans cycles of DR1 dye under the polarized laser light illumination. We discuss a stochastic master equation which generalizes the simple model of Ref.2 and address briefly the topic of non-exponential grating inscription in modelling and in recent experiments.
