in the group of Egon Wiberg. In 1964 he received his post doctoral lecture qualification after work on phosphorus
containing diacenes
in the same research group. Subsequentely he had a three-years visit in the group of Edgar Heilbronner
at ETH Zurich
/Switzerland, where he worked on applications of the HMO-model
, leading to the textbook: The HMO model and its application.
In 1968 he was announced full professor for inorganic chemistry at the University of Frankfurt.
He focussed on preparation of element-organic compounds and their characterisation by appropiate physical measurement methodes. Main focus was set on development and application of X-ray photoelectron spectroscopy
(XPS) for detection and characterisation of transient molecules.
He proposed the use of the super silyl group in 1993.

Career
Hans Bock studied chemistry at the University of Munich, where he received his PhD in 1958 for his work on water-free hydrazineHydrazine
Hydrazine is an inorganic compound with the formula N2H4. It is a colourless flammable liquid with an ammonia-like odor. Hydrazine is highly toxic and dangerously unstable unless handled in solution. Approximately 260,000 tons are manufactured annually...
