- Highly Solid-State Emissive Pyridinium-Substituted Tetraphenylethylene Salts: Emission Color-Tuning with Counter Anions and Application for Optical Waveguides
Fang Hu, Guanxin Zhang, Chi Zhan, Wei Zhang, Yongli Yan, Yongsheng Zhao, Hongbing Fu and Deqing Zhang
Article first published online: 22 OCT 2014 | DOI: 10.1002/smll.201402051
Pyridinium-substituted tetraphenylethylene salts with seven different anions show almost the same emission behavior in an amorphous state, except the salt with I−, but their crystalline solids have different emission colors varying from green to yellow. These can be tuned using the counter anions; in addition, microrods of certain salts can function as great optical waveguides.

Synergetic advantages of superior electrical conductivity and excellent reaction activity from inorganic lattices render 2D nanomaterials ideal candidates for electrode active materials in electrochemical applications towards energy conversion and storage. In this concept article, recent progress on regulating the electrical behaviors of two-dimensional inorganic nanomaterials for energy applications are discussed.
- Single-Mode Lasing from Colloidal Water-Soluble CdSe/CdS Quantum Dot-in-Rods
Francesco Di Stasio, Joel Q. Grim, Vladimir Lesnyak, Prachi Rastogi, Liberato Manna, Iwan Moreels and Roman Krahne

In optoelectronic device fabrication, water solubility of nanocrystal materials is advantageous for simple and environmentally friendly processing routes. Towards LEDs, highly luminescent core–shell quantum dot-in-rods (QDRs) demonstrate excellent performance as emitters. Increasing in shell thickness allows the transfer of CdSe/CdS QDRs into aqueous solution without reducing their emission, and drop deposition leads to single mode microlasers with low threshold.
- Tailoring the Height of Ultrathin PbS Nanosheets and Their Application as Field-Effect Transistors
Thomas Bielewicz, Sedat Dogan and Christian Klinke
Article first published online: 21 OCT 2014 | DOI: 10.1002/smll.201402144
Controlled synthesis of large, two-dimensional PbS nanosheets with tunable height is presented. Through a variation in ligand concentration it is possible to tailor the height of the PbS nanosheets, which show different optical and electronic characteristics as a function of their height.
- Rapid Quantification of Live Cell Receptors Using Bioluminescence in a Flow-Based Microfluidic Device
Ramesh Ramji, Cheong Fook Chiong, Hiroaki Hirata, Abdur Rub Abdur Rahman and Chwee Teck Lim
Article first published online: 21 OCT 2014 | DOI: 10.1002/smll.201401674
A new method of quantifying live cell surface receptor numbers by integrating bioluminescence with microfluidics and lens-free optics is presented. This significantly improves upon other methods by providing miniaturized detection modules with higher sensitivity, specificity, lower consumption of analytes, reduced assay times, and by allowing multiplex functions for high-throughput cell screening assays.
