A simple and practical synthesis of soluble hexa-peri-hexabenzocoronene (HBC) from readily available hexaphenylbenzene (HPB) is described. In this simple procedure, the substitution of the free para positions of the propeller-shaped HPB with tert-butyl groups and the oxidative cyclodehydrogenation to planar HBC is achieved in a one-pot reaction using ferric chloride both as a Lewis acid.

Dubai, United Arab Emirates. Dubai is where it all started!!!

Dubai have been the start point of all the Goodwill Journey trips and will be the start and end point of the coming trip Around the World. For me Dubai is the place I call Home. Dubai is one of the few cities in the world that has undergone such a rapid transformation - from a humble beginning as a pearl-diving centre - to one of the fastest growing cities on earth. Dubai today is a tourism, trade and logistics hub and has earned itself the reputation of being the ‘gateway between the east and the west.’ It is also considered as the dynamic nucleus of the Arabian Gulf region.

Home to just over 2 million people from more than 200 nationalities, Dubai is one of the most cosmopolitan cities in the world. Living in Dubai has a lot to offer. It is safe, politically stable, centrally located, has a good education system and healthcare facilities, modern infrastructure and much more. The sun shines almost every day, the shopping and leisure facilities are impressive, and the salaries are tax-free.

Feringa received his Ph.D. Degree from the University of Groningen in 1978 with Professor Hans Wynberg.

He has been a research scientist with Royal Dutch Shell at the research center in Amsterdam and at the Shell Biosciences Laboratories in Sittingbourne, U.K., from 1978 to 1984. He then joined the Department of Chemistry at the University of Groningen as a lecturer.

In 1988 he was appointed Professor at the same university. He was a Visiting Professor at the University of Leuven, a JSPS fellow, and 1997 recipient of the Pino gold medal of the Italian Chemical Society. His research is mainly focused on stereochemistry, and his research interests include organic synthesis, asymmetric catalysis and catalytic oxidation, molecular switches and motors, self-assembly, and new organic materials. Van Delden was born in 1974. He started his studies in the group of Professor B. Feringa at the University of Groningen in 1994 on the excited-state properties of chiroptical molecular switches based on sterically overcrowded alkenes.

In 1996 he spent six months in the group of Professor M. Green, Brooklyn Polytechnic University, performing research on the chiral properties of binaphthalene solubilized in aqueous polymer solutions. On the basis of these projects he received his B.A. Degree in Organic Chemistry with honors in 1997. In the same year he started his Ph.D. Study under the guidance of Professor B.
