Conjugated copolymers by Horner‐Emmons polycondensation and electroluminescence characteristics
Source abstract
Abstract
Abstract Four types of conjugated polymers, poly(MEHPV‐PV), poly(MEHPV‐BPV), poly(MEHPV‐AV) and poly(PZV‐AV) were synthesized by Horner‐Emmons reaction using potassium tert‐butoxide. The Horner‐Emmons reaction gave electroluminescent(EL) copolymers in good yield. Of the EL copolymers synthesized, poly(PZV‐AV) containing phenothiazinylene vinylene and anthrylene vinylene as repeat unit exhibited red color in the light emitting diode(LED) which was very close to the NTSC standard red. Besides, double layer LED made with Alq3 electron transport layer exhibited both enhanced emission intensity and efficiency compared to the single layer LED.
