Arylsilanes and siloxanes as optoelectronic materials for organic light-emitting diodes (OLEDs)
Arylsilanes and siloxanes have been extensively studied as components of OLEDs. In this review, we summarize the recent advances in the utilization of arylsilanes and siloxanes as fluorophore emitters, hosts for phosphor emitters, hole and exciton blocking materials, and as electron and hole transporting materials.

About this collection
Introduced by Professor Peter Skabara, University of Strathclyde
I am delighted to introduce this exciting and hugely impressive web collection highlighting the cream of UK research in materials chemistry which has been published in Journal of Materials Chemistry C in 2015. It is extremely pleasing to see that the collection features well-established scientists, most of who have been publishing in the Journal of Materials Chemistry family of journals throughout their careers. It is equally pleasing and exciting to see the new crop of young talented researchers emerging who will continue to showcase outstanding materials research for the UK community for many years to come.
The work highlighted in this collection covers a wide spectrum of materials chemistry including compound semiconductors and soft matter, processing and devices, new research and a splendid review on the application of silanes and siloxanes in OLED devices.
This collection provides an excellent snapshot of contemporary materials research in the UK. Read the articles and be prepared for some super science.
Best wishes Peter
