A new simple pyrene‐substituted acylhydrazone derivative, 4‐(3,4‐dioctyloxy) phenyl‐1‐pyrene acylhydrazone (PAH‐8), was designed and synthesized. The PAH‐8 can form thermo‐reversible organogel in DMSO, and shows gelation‐induced enhanced fluorescence emission. Xerogel exhibits ribbon‐like fibrous aggregates with widths of 0.5‐1 μm. The PAH‐8 organogel indicates photo‐responsive behaviors due to the...
An anthracene-based gelator (AHP-mB8) has been designed and synthesized. AHP-mB8 can form thermo-reversible gels in some of the tested solvents. FTIR, temperature-dependent 1H NMR, UV–vis and XRD spectra indicated that the gelator self-assembles into a fibrous network possibly due to the combination of intermolecular hydrogen bonding and π–π interactions. The anion binding studies indicated that AHP-mB8...
The photophysical properties of 2,2′-bis-(4-alkoxyphenyl)-bi-1,3,4-oxadiazole (BOXD-n), have been studied by a combination of spectroscopic techniques and theoretical calculations. Interestingly, strong fluorescence red-shift in polar solvents was observed in this highly symmetric molecule, which indicates an efficient charge transfer (CT) occurred in the excited state. The change of molecular dipole...
