Preparation, Optical Properties and Yellow Electroluminescence of Water-Soluble Poly(p-phenylene vinylene)

Abstract

Novel carboxy-substituted poly(p-phenylene vinylene), poly(1,4-(2-(5-carboxypentyloxy)-5-methoxyphenylene)vinylene) (CPMOPPV) has been synthesized. The obtained polymer is soluble in organic solvents, such as acetone and ethanol, and the sodium salt of CPMOPPV is soluble even in water. The optical properties of CPMOPPV, such as optical absorption and photoluminescence have been studied, and yellow-electroluminescence devices have been fabricated. The electronic energy structure of CPMOPPV has been determined by optical and electrochemical measurements. CPMOPPV has been demonstrated to be one of the candidate polyanions for fabrication of the organic multilayer structure by the self-assembly technique.

Design and Synthesis of Conjugated Polyelectrolytes

“…Carboxylated poly(phenylene vinylene)s were also synthesized via the Heck [73] and Gilch reactions [121,122]. Copolymerization between 108 and 109 catalyzed by Pd(OAc) 2 /P(o-Tol) 3 The same group also synthesized a cationic poly(phenylene vinylene) P144 via the Gilch reaction (Scheme 1.56) [76].…”

Optical properties of self-assembled thin-film of poly(p-phenylene vinylene)s and its application to light-emitting devices with microring geometry

“…Recently, we have developed a PPV derivative, poly͕1,4-͓2-͑5-carboxypentyloxy͒-5-methoxyphenylene͔vinylene͖ ͑CPMOPPV͒, for the selfassembly method, and studied its optical and electrical properties. 10 Since this polymer indicates the characteristics of a polyanion, self-assembled alternating multilayer structures based on PPVs could be formed utilizing PPV precursor as a polycation. 11 On the other hand, polymer lasers with microring structure have attracted much attention as a novel type of lasers.…”

Triphenylamine and Fluorene Based Cationic Conjugated Polyelectrolytes: Synthesis and Characterization

“…[1] These unique properties provide many new opportunities for CPEs in optoelectronic and biological applications. Varieties of CPEs with different backbones, such as polythiophene (PT), [2][3][4][5] poly(phenylene vinylene) (PPV), [6][7][8][9] poly(paraphenylene) (PPP), [10][11][12][13][14] poly(phenylene ethylene) (PPE), [15][16][17][18][19][20][21][22] polyfluorene (PF) [23][24][25][26][27][28] and polycarbazole (PCz) [29] have been successfully synthesized. Water-soluble CPEs have been used very successfully as biosensors, [30][31][32] self-assembly systems [33][34] and several attempts have been made to use CPEs as the active layer in PLEDs.…”
