Green light-emitting polyfluorenes with improved color purity incorporated with 4,7-diphenyl-2,1,3-benzothiadiazole moieties

By incorporating 4,7-diphenyl-2,1,3-benzothiadiazole instead of 2,1,3-benzothiadiazole into the backbone of polyfluorene, we developed a novel series of green light-emitting polymers with much improved color purity. Compared with the state-of-the-art gree

Tetra-benzothiadiazole-based [12]Cycloparaphenylene with Bright Emission and Its Supramolecular Assembly

The radial conjugated π-system of cycloparaphenylenes (CPPs) makes them intriguing fluorophores and unique supramolecular hosts. However, the bright photoluminescence (PL) of CPPs was limited to the blue light and the supramolecular assembly behavior of l

Highly stable and bright fluorescent chlorinated polymer dots for cellular imaging

Chlorinated organic materials have drawn much attention and have been applied in various fields due to their intriguing properties such as easy accessibility with low cost, high capability to hold electron density, and “heavy-atom effect”. In this work, a

Synthesis and characterization of dumbbell-like BTD-based derivatives to engineer organic building blocks in solid-state

Four BTD-derivatives 4, 5, 7 and 8 were synthesized and characterized by using solution NMR, FTIR and HRMS. In this study, BTD-central cores were supported on trityl type fragments in order to evaluate the influence of these groups prone to aggregation through interdigitation in the consolidation of ordered solids. Structural variation, between compounds 4–5 and 7–8, was selected by introducing aromatic phenyl rings at positions C-4 and C-7 of the BTD central core in order to increase the stackable surface. Crystals of compounds 4 and 5 were obtained and solved in the C2/c and P21/c space groups, respectively. Both crystalline arrays are dominated by C[sbnd]H?π and π-stacking interactions, desirable features for the bottom-up construction of highly polarizable organic crystals. The featured compounds with a dumbbell-like structure could be useful as scaffolds for self-assembled crystalline materials such as solid organic semiconductors.

Two quinoxaline derivatives designed from isomer chemistry for nonvolatile ternary memory device applications

In this paper, two quinoxaline-based small organic molecules, which are conjugated and mutual isomers in vertical and horizontal directions, were successfully synthesized. By exploring isomers with identical functional groups, the impact from changing in

Bright and photostable organic fluorescent dots with aggregation-induced emission characteristics for noninvasive long-term cell imaging

Efficient long-term cell tracing in a noninvasive and real-time manner is of great importance to understand genesis, development, invasion, and metastasis of cancerous cells. Cell penetrating organic dots with aggregation- induced emission (AIE) characteristics are successfully developed as long-term cell trackers. The AIE dots enjoy the advantages of high emission efficiency, large Stokes shift, good biocompatibility, and high photostability, which ensure their good performance in long-term non-invasive in vitro cell tracing. Moreover, it is the first report that AIE dots exhibit certain permeability to cellular nucleus, making them attractive potential candidates for nucleus imaging. The AIE dots display superior performance compared to their counterparts of inorganic quantum dots, opening a new avenue in the development of fluorescent probes for monitoring biological processes. Encapsulation of orange-red fluorescent luminogens with aggregation-induced emission (AIE) characteristics in biocompatible matrix yields AIE dots with strong emission, large Stokes shift, good biocompatibility, and high photostability. Application of the AIE dots for in vitro cell tracing and nucleus imaging has been demonstrated using MCF-7 breast cancer cells as an example.
