An azo dye DR1 was incorporated into DNA complex (DNA-CTMA) films as a guest dispersed in the host or as a copolymer (pDR1) side chain blended with the complex. Although the guest did not show photo-isomerization response, DR1 side chain in the blend showed photo-induced birefringence and photo-induced transparency under the excitation at 532 nm. Several cationic dyes were incorporated into pDR1/DNA-CTMA films with immersion method. Rhodamine 640 perchlorate showed amplified spontaneous emission with the excitation above 10mJ/cm2 by a pulsed laser of 532 nm.
