From the viewpoint of practical application, organic materials that are emissive in aggregate or solid state have been a hot research topic. This work demonstrates that 2,2′:5′,2″-terthiophene-5-carbaldehyde (TTA) exhibited aggregation-induced emission (AIE) property. The photophysical properties of the aldehyde in THF/H2O mixtures were studied, and the aggregates formed with different water fractions were studied by scanning electron microscopy. Our results indicated that the presence of an electron deficient aldehyde group as the end-capped group should endow TTA with AIE characteristic. Furthermore, ordered nanoscale aggregates of TTA exhibited distinct AIE behavior when assembled in solutions with appropriate water content.

A surfactant-assisted unimolecular platform for multicolor emissions

We present here a simple molecular assembly approach to multicolor emissions based on a unimolecular platform of a terthiophene-containing amphiphile TTC4L. The amphiphiles self-assemble into vesicles in solution which exhibit a blue emission. Upon controlling the distance between the fluorescent terthiophene groups by transformation of the self-assembly of TTC4L molecules into their co-assembly with surfactants, the color of the emissions can be continuously tailored which covers most of the visible region. Since the multi-colors were obtained without any structural modification on the fluorescent molecules, we have demonstrated a real unimolecular platform for fabricating multicolor emissions. In contrast, only dual emissions can be obtained from TTC4L using host-guest chemistry. As a simple approach of 'tunable emissions', this surfactant-assisted unimolecular platform opens a new vista for the application of molecular assemblies in advanced light emitting materials.
Self-assembly facilitated and visible light-driven generation of carbon dots

Carbon dots (CDs) with an absolute fluorescence quantum yield of 87% are facilely prepared via irradiation of self-assembled terthiophene amphiphile TTC4L in aqueous solution by mild visible light. Visible light irradiation of TTC4L triggers the production of superoxide radicals in water, which oxidize the closely packed terthiophene group into carbon dots. Our results reveal that the molecular self-assembly may act as important precursor for the generation of single molecule-like carbon dots; this method paves the way for the fabrication of CDs of high quality.

A series of α-terthiophene derivatives were prepared and their protein kinase C inhibitory activity were evaluated. The aldehyde derivatives were most potent inhibitors (IC50 1 μM). 2a-Terthiophene monoaldehyde was inactive in the inhibitions of protein kinase A, mitogen activated protein kinase and protein tyrosine kinase.

Several derivatives of 2,2':5',2''-terthiophene, 1a, and a structural analogue of this natural phototoxin, i.e. 5--2,2'-bithiophene, 2, have been conveniently synthesized on a medium scale using a general approach which involves palladium-catalyzed carbon-carbon bond forming reactions between (hetero)aryl halides and heteroaryl organometallics such as Grignard reagents, organozinc and organotin compounds.These 2,2':5',2''-terthiophene derivatives, which include some naturally-occurring compounds, have been characterized by EIMS spectrometry , 1H and 13C NMR spectroscopy as well as by absorption and fluorescence measurements.Four of these phototoxins exhibit considerable antibiotic and antiviral properties in the presence of UVA light and are cytotoxic against the P 815 mouse mastocytoma cell line.
