Abstract: A new soluble phthalocyaine 1(4),8(11),15(18),22(25)-tetra-(methoxy-phenoxy)phthalocyanine (MPPc) was synthesized and verified by mass spectrum (MS), 1H NMR, IR and elemental analysis. The methoxy-phenoxy groups were introduced in order to enhance the solubility of the phthalocyanine. The photophysical and electroluminescent properties were investigated. The organic light-emitting diodes (OLEDs) with the structure of ITO/PVK:MPPc(40 nm)/BCP(20 nm)/Alq3(30 nm)/Al were fabricated. Room-temperature near infrared (NIR) electroluminescence (EL) was observed near 891 nm that effectively covered the ?rst optical communication window near 850 nm.
