Preface to the Chemistry of Materials Special Issueon π-Functional Materials
While the history of synthetic π-conjugated organic systems dates back to theeighteenth century, their use was largely based on their ability to serve as dyes andpigments. However, since the development of organic photoconductors for the xerogra-phy industry in the 1960s and the realization by Heeger, Shirakawa, and MacDiarmidthat conjugated polymers can be turned into electrically conducting materials (that is,“synthetic metals”) in the 1970s, the field has witnessed a flurry of activities that haveturned conjugated materials into active elements enabling a wide range of electronic,opto-electronic, and photonic technologies with extensive applications. An additionalcharacteristic of π-conjugated compounds is the possibility of combining electrical andoptical activity with the mechanical properties typical of plastics in a single material.These characteristics have opened theway to flexible devices basedonorganic thin films.A testament to the impressive development of the field and to the innovations it spurredis that organic electronics is projected to become a US$ 30B industry by 2015.The versatility of the chemistry available for the synthesis of conjugated molecules,
oligomers, polymers, or dendrimers, coupled with theoretical modeling, providesopportunities for the design of compounds with well-defined, tunable electronic andoptical properties. Yet, the translation of the properties of the individualmolecular levelbuilding blocks into the desired bulk materials properties remains a challenge that is farfrom being met. As a consequence, significant developments in the materials chemistryof these systems from both experimental and theoretical points of view are required torealize the full potential of this important class of materials.It is the goal of this Special Issue to provide a broad overview of the state-of-the-art in
the field of π-Functional Materials. The contributions cover the chemistry of materialswith specific electronic, optical, nonlinear optical, magneto-optical, and/or photophys-ical properties that can be exploited in a wealth of applications as diverse as organicfield-effect transistors, light-emitting diodes, solid-state lighting, sensing, photovoltaics,electro-optics, or photorefractivity.The call for papers for the Special Issue has been receivedwith great enthusiasmby the
