Synthesis and nonlinear optical properties of novel polyester containing dicyanovinylnitrocatecholic group

A novel X-type polyester containing 4-(2′,2′-dicyanovinyl)-5-nitrocatecholic groups as nonlinear optical (NLO) chromophores, which constitute part of the polymer backbone, was prepared and characterized. The polyester is soluble in common organic solvents such as N,N-dimethylformamide and acetone. It shows a thermal stability up to 300°C from thermogravimetric analysis with glass-transition temperature obtained from differential scanning calorimetry of near 105°C. The second harmonic generation (SHG) coefficient (d33) of a poled polymer film at the 1064?nm fundamental wavelength is 5.31 × 10?9 esu. The dipole alignment exhibits a thermal stability even at 5°C higher than glass-transition temperature (Tg), and no significant SHG decay is observed below 110°C due to the partial main-chain character of polymer structure, which is acceptable for NLO device applications.

Synthesis and properties of novel nonlinear optical polyester containing carbomethoxycyanovinylnitrocatecholic group

A new X-type polyester 5 containing 4-(2′-carbomethoxy-2′-cyano)vinyl-5-nitrocatecholic groups as nonlinear optical (NLO) chromophores, which are parts of the polymer backbone, was prepared and studied its properties. Polyester 5 is soluble in common organic solvents such as acetone and dimethylsulfoxide. Polymer 5 shows a thermal stability up to 280°C from thermogravimetric analysis with glass-transition temperature (Tg) obtained from differential scanning calorimetry of near 110°C. The second harmonic generation (SHG) coefficient (d33) of poled polymer 5 film at the 1064?nm fundamental wavelength is 6.13 × 10?9 esu. The dipole alignment of polymer 5 exhibits a thermal stability up to Tg, and no significant SHG decay is observed below 110°C due to the partial main-chain character of polymer structure, which is acceptable for NLO device applications.

Synthesis of novel Y-type nonlinear optical polyester with enhanced thermal stability of second harmonic generation for electro-optic applications

Methyl 3,4-di-(2'-hydroxyethoxy)benzylidenecyanoacetate (3) was prepared and condensed with terephthaloyl chloride to yield novel Y-type polyester (4) containing 3,4-dioxybenzylidenecyanoacetate groups as NLO-chromophores, which constituted parts of the polymer main chains. The resulting polymer 4 is soluble in common organic solvents such as acetone and A-dimelhylformarnide. Polymer 4 shows thermal stability up to 280 °C in thermogravimetric analysis with glass-transition temperature obtained from differential scanning calorimetry near 105 °C. The second harmonic generation (SHG) coefficient of poled polymer films at the 1064 nm fundamental wavelength is around 2.42 pm/V. The dipole alignment exhibits high thermal stability up to near Tg, and there is no SHG decay below 100 °C due to the partial main-chain character of polymer structure, which is acceptable for NLO device applications.

Synthesis and electro-optic properties of novel Y-type polyurethanes having dioxybenzylidenemalononitrile

3,4-Di-(2′-hydroxyethoxy)benzylidenemalononitrile (3) was prepared and condensed with 2,4-toluenediisocyanate and 3,3′-dimethoxy-4,4′- biphenylenediisocyanate to yield unprecedented novel Y-type polyurethanes (4-5) containing 3,4-dioxybenzylidenemalononitrile group as a NLO-chromophore, which is a part of the polymer main chain. The resulting polyurethanes 4-5 were soluble in common organic solvents such as acetone and DMF. Polymers 4-5 showed a thermal stability up to 280°C in TGA thermograms with Tg values from DSC thermograms in the range of 148-152°C. The SHG coefficients (d33) of poled polymer films were around 5.96 × 10-9 esu. These poled polymer films exhibited greater thermal stabilities of dipole alignments even at 20°C higher than Tg due to the partial main chain character of the polymer structure, which is acceptable for NLO device applications.

Methyl 3,4-di-(2'-hydroxyethoxy)benzylidenecyanoacetate 3 was pre pared and condensed with 2,4-toluenediisocyanate and 3,3'-dimethoxy-4,4'- biphenylenediisocyanate to yield polyurethanes 4 and 5 containing the NLO-phore dioxybenzylidenecyanoacetate group. The resulting polyurethanes 4-5 were soluble in common organic solvents. Polymers 4-5 showed a thermal stability up to 290°C in TGA thermograms with Tg values in the range of 97-102°C in DSC thermograms. The SHG coefficients (d33) of poled polymer films were 4.7 × 10-9 esu.
