Freudenberg, Jan,Rominger, Frank,Bunz, Uwe H. F.
, p. 16749 - 16753 (2015)
The synthesis of five novel distyrylbenzene (DSB) derivatives, featuring a central tetraphenylbenzene core, is reported. The targets show aggregation-induced emission (AIE), which, however, is substituent-dependent. For the pure hydrocarbon and derivative

To evaluate the potential of monoolein-based cubic bicontinuous liquid crystalline nanoparticles (cubosomes) as diagnostic tools in diabetes and pancreatic β-cell transplantation, fluorescent cubosomes were formulated, entrapping within the lipid bilayer a newly synthesized, potent, hydrophobic dye. Cryo-TEM, SAXS, and DLS were performed to assess the morphological and structural aspects of this formulation. Rat pancreatic β-cells (INS-1E) readily took up the cubosome nanoparticles, as revealed by in vitro internalization tests, and flow-cytometric analyses confirmed the persistence of the fluorescence for up to 24 hours. The cytotoxicity of cubosomes at various concentrations, evaluated with a real-time analysis of proliferation, revealed that the proliferation curves relative to the less concentrated formulation (5 μM in terms of monoolein content) were comparable to the untreated cultures. INS-1E cell cycle and apoptosis supported such results. In conclusion, this formulation, with dye content in the nanomolar range, seems to be useful for β-cell imaging.

A series of chromophores T1-T3 based on the same thiophene π-conjugation and tricyanofuran acceptor (TCF) but with different heteroatoms in the triarylaminophenyl (TAA) donors have been synthesized and systematically investigated in this study. Density functional theory (DFT) was used to calculate the HOMO-LUMO energy gaps and first-order hyperpolarizability (β) of these chromophores. Moreover, to determine the redox properties of these chromophores, cyclic voltammetry (CV) experiments were performed. After introducing the heteroatom to the benzene ring of the TAA donor, reduced energy gaps of 1.28 and 0.84 eV were obtained for chromophores T2 and T3, respectively, which was much lower than for chromophore T1 (ΔE = 1.46 eV). These chromophores showed excellent thermal stability with their decomposition temperatures all above 280 °C. Compared with results obtained from the chromophore without the heteroatom (T1), these new chromophores show better intramolecular charge-transfer (ICT) absorption. Most importantly, the high molecular hyperpolarizability (β) of these chromophores can be effectively translated into large electro-optic (EO) coefficients (r33) in the poled polymers. The electro-optic coefficient of poled films containing 25 wt% of these new chromophores doped in amorphous polycarbonate (APC) afforded values of 16, 58 and 95 pm V-1 at 1310 nm for chromophores T1-T3, respectively. High r33 values indicated that introducing heteroatom to the benzene ring of the TAA donor can efficiently improve the electron-donating ability, which improves the hyperpolarizability (β). The long-chain on the benzene ring of the TAA donor, acting as the isolation group, may reduce intermolecular electrostatic interactions, thus enhancing the macroscopic EO activity. These properties, together with the good solubility, suggest the potential use of these new chromophores as advanced material devices. This journal is
