Role of synergistic π-π Stacking and X-H...Cl (X = C, N, O) H-bonding interactions in gelation and gel phase crystallization

The self-assembly of p-pyridyl-ended oligo-p-phenylenevinylenes (OPVs) in ethanol leads to the formation of either hollow or solid microrods. The corresponding protonated OPVs with n-butyl chains induce transparent gelation and also gel phase crystallization owing to various synergistic noncovalent interactions. The chloride ion-selective gelation, AIEE and stimuli responsiveness of the gel are also observed. This journal is

Novel isoindigo-based conjugated polyelectrolytes: Synthesis and fluorescence quenching behavior with water-soluble poly(p-phenylenevinylene)s

Two novel ID-based water-soluble conjugated polymers (+)-PIDPV and (-)-PIDPV were synthesized by Heck coupling reaction. These two polyelectrolytes are both consisted of isoindigo units and phenylenevinylene units. In the UV-vis absorption spectra, both (+)-PIDPV and (-)-PIDPV exhibit broad absorption bands that almost cover the whole visible region. Photophysical investigations reveal that the fluorescence of water-soluble PPV can be efficiently quenched by oppositely charged PIDPV at a very low concentration. Cationic PPV shows an efficient quenching effect with ΚSV = 1.01 × 106 M-1 in the presence of (-)-PIDPV while the anionic PPV gives a lager quenching constant with ΚSV = 1.71 × 106 M-1 in the presence of (+)-PIDPV. Furthermore, the blend films of water-soluble PPVs and oppositely charged PIDPV also exhibit excellent quenching effect. These properties suggest that (+)-PIDPV and (-)-PIDPV are promising materials in the application of ionic photoactive layer in the organic solar cells.
