Abstract

Many red fluorescent materials were weak and even no luminescence in solid state due to concentration quenching. So a novel red fluorescent pigment bis(4-(N-(9-phenanthryl)-3,5-dimethyl- phenylamino)phenyl)fumaronitrile (PhMPAFN) was synthesized. PhMPAFN with a pair of antiparallel dipole suppressing molecular interaction exhibited strong red photoluminescence at 650 nm in solid film. The decomposition temperature was found at 424 C. In different polarity of solvents the absorption and emission peaks of PhMPAFN showed positive and then negative solvatochromic shifts. PhMPAFN in tetrahydrofuran/water (1:1, 1:3, 1:5, 1:9, v/v) was aggregated into fluorescent organic nanoparticles (FONs) in the range of 164 and 531 nm (coverage rate over 98 %). FONs displayed strong aggregation-induced emission at about 620 nm and had potential use in nano-sized fluorescence and optoelectronic device.
