Abstract:

A novel second-order NLO azo-chromophore containing thiophene conjugated bridge and TCF acceptor was synthesized and characterized by means of IR, UV, MS and  1H NMR. Two types of crosslinking polyurethane containing this chromophore were prepared, in which TEA and BPAN acted as the crosslinking agents, respectively. Second harmonic coefficient d33 values for the two polymers were measured by Marker-fringe method at 1 064 nm, they were 20.1 pm/V(chromophore number density is 2.21×1020 molecules/cm3) and 80.6 pm/V(chromophore number density is 0.91×1020 molecules/cm3), respectively. Polymer Ⅱ showed a thermal stability of 152 ℃, which was 71 ℃ higher than polymer Ⅰ.
