Current Organic Synthesis - Volume 9, Issue 2, 2012

π-Conjugated organic small molecules and polymers have found a number of applications for use in plastic electronics. One key aspect of organic materials is their versatility. Organics exhibit a remarkable flexibility in the synthesis at molecular level, allowing for tunability of a wide range of properties. Additionally, their use offers the prospect of low manufacturing costs, large area coverage, lightweight and compatibility with Read More

This review reports a survey of our recent results on the synthesis of arylenevinylene polymers and oligomers selectively functionalized with fluorine atoms on aromatic and/or vinylene units. The synthetic methods developed are based on Pd-catalyzed organometallic cross-coupling reactions and in particular on the Stille coupling between vinyl organotin derivatives and aromatic halides. Several compounds have bee Read More

In the past two decades, π-conjugated organic compounds have attracted much attention due to their potential applications in various fields such as liquid crystals, light-emitting, and nonlinear optical materials and self assembling. Introduction of heteroaryl moieties into π-extended systems are particularly useful where electron transfer is necessary and is a way to modify and sometimes enhance properties of advanced “ele Read More

Mechanically-interlocked molecules have been considered for many years only aesthetically appealing structures but nowadays they are finding interesting applications in the field of artificial molecular machines and electronic devices. Improved template-directed protocols have allowed highly programmable and efficient syntheses of rotaxanes and catenanes. In particular those compounds which exhibit bi- and multistab Read More

Rotaxanes are currently seen as one of the most promising components in artificial molecular machines. In the last few decades, much effort has been dedicated to the developing of such interlocked architectures, which can be subjected to different types of submolecular motion. The field of Rotaxanes has evolved to stimuli-responsive molecular shuttle, capable of responding to several different external stimuli. The interest i Read More

A comprehensive overview on the main applications of state-of-the-art computational methodologies to the simulation of Dye- Sensitized Solar Cells (DSSCs) based on metal-free organic dyes is reported. The presented results cover two crucial aspects that should be carefully taken into account in the design of novel and highly efficient sensitizers, namely the electronic structure of the dye (spectroscopic and redox properties) an Read More

Self-assembly provides a unique method for creating supramolecular functional materials. A significant progress in the synthesis and characterization of boronic acid-based supramolecular structures has been achieved in recent years. Macrocycles, dendritic structures, polymers, rotaxanes, and cages have been assembled using four types of reversible reactions. We herein elucidate the key point of the strategy, t Read More

Recent advances in the development of environmentally friendly recyclable reagents and catalytic systems based on hypervalent iodine are discussed. The review covers the following topics of active current research: polymer-supported iodine(III) and iodine(V) oxidants, recyclable monomeric hypervalent iodine(III) reagents, reactions of hypervalent iodine in solid state, application of water or recyclable organic solv Read More
