In this paper, twenty novel meso-substituted porphyrins of four series were designed and synthesized by increasing the conjugation of porphyrins or introducing substituents with high fluorescence quantum yield into the meso-position of porphine, and then red OLEDs were fabricated by doping porphyrins into a suitable host using ten porphyrins compounds and their electrolumin -escence properties were tested. The main contents and results were generalized as follows:Three meso-tetrakisporphyrins 4a-c and three conjugations of porphine-triarylamine linked by styrene 10a-c were synthesized and characterized by 1H NMR, MS, UV-vis spectra and fluorescence emission spectra.
