Current Organic Chemistry - Volume 11, Issue 14, 2007

The present issue of Current Organic Chemistry is devoted to organic functional materials with special emphasis on material design, synthesis and relationship between structure-application performance. The authors provide us an up-to-date discussion on the special application area, such as PLED, OFET, DSSCs and photochromism. Polyfluorene-based conjugated polyelectrolytes (CPs) exhibit excellent unique characteristics di Read More

Conjugated Polyelectrolytes (CPs) have been successfully used as highly sensitive materials in chemo and biosensors for many years. But in general CPs were not very successful as a light emitting layer in polymer light-emitting diodes (PLEDs). Until recently, it was found that polyfluorene-based CPs and their precursors showed excellent unique characteristics different from the traditional conjugated polymers as light-emitting ma Read More

This review is focused on current state of materials design and syntheses of organic semiconductors for thinfilm field effect transistors (FETs). Recently, high performance p- or n-type organic FETs with high charge carrier mobility, high ON-OFF current ratios and high stability have been achieved due to the improvement of materials syntheses. Intrinsic electronic properties, solid-state packing, stability, and the capability Read More

Dye-sensitized solar cells (DSSCs) have received considerable attentions as a cost-effective alternative to conventional solar cells. One of main issues for the development of DSSCs is the design and synthesis of dyes that serve as light absorbers for energy conversion. Up to now, many different pure organic dyes and transition metal complexes have been evaluated as sensitizers. DSSCs sensitized with pure organic dyes Read More

Photochromic diarylethene have received considerable attention because of their potential photonic applications. All of these applications come from the fact that when stimulated with light at appropriate wavelengths, the physical and chemical properties can be reversibly modulated. During the last decade, more and more decoration on the general structures of diarylethene and novel skeletons beyond the general structures Read More

Dye sensitized solar cells (DSSCs) have great potential to challenge the traditional silicon-based semiconductor solar cells in the photovoltaic (PV) market because of their low cost and medium efficiency. This type of solar cell has achieved an impressive photo-to-energy conversion efficiency of over 10%. In a dye sensitized solar cell, the charge separation is initiated at the adsorbed dye, which was bound at the interface of an in Read More
