The present Letter reports electrical and optical properties of our newly synthesized organic-titanium hybrid polymer, (2,3-dicyanophenyl bis-2,4-pentanedionate titanium alkoxide) (PDC–PD–Ti). The main chains of PDC–PD–Ti consist of alternate titanium ions and phenylene groups by way of oxygen atoms. Electrically poled amorphous polymer systems are active in pyroelectricity, because of ordering of the cyanate groups in the side chains. The linear optical response is likely associated with a photo-excitation into a delocalized electronic excited level extending from titanium ion to π-conjugated phenylene group. Furthermore, the material exhibits second order nonlinear optical activity after the electrical poling procedure.
