Paper Abstract

Recently, we have proposed a simplified kinetic Monte Carlo model which mimics the inscription/erasure of diffraction gratings in DNA matrix with azodyes. Preliminary results correctly reproduce the observations made for the photochromic system DR1:DNA-CTMA: very short operational times (inscription/erasure), optical stability and reversibility. In this paper we analyze semi-intercalation model of paper analytically and discuss its predictions. Next, we modify this model by taking the DNA model chain directly into account. Local free volume determines the transition probabilities of trans-cis photoisomerization reactin. Using the model we address the open questions: (i), short operational time; (ii), small diffraction efficiency; and (iii), one exponential inscription.
