Paper Abstract

We use the recently formulated hypothesis of semi-intercalation of an azo-dye Disperse Red 1 (DR1) into a biopolymeric material made of deoxyribonucleic acid (DNA) complexed with the cationic surfactant hexadecyltrimethylammonium chloride (CTMA)1-3 to model the unique photochromic properties of the DR1:DNA-CTMA system. First results of kinetic Monte Carlo simulations accurately reproduce4 the main experimental results5 of laser dynamic inscription of diffraction gratings in this photochromic material: short response time, low diffraction efficiency, single-exponential kinetics and flat wavelength dependence. Results of systematic MC studies are presented. The question of extending the model of paper4 by including into it probabilistic features of local free volume in DNA matrix is discussed.
