Recently, the bond-energy databank (iBonD 2.0) established by Academician
Cheng Jinpei’s group has received high value from Prof. Herbert Mayr from
University of Munich, a well-known physical organic chemist and member of the
German Academy of Sciences. He specifically published a paper entitled “The
Most Efficient Way to Find pKa Values” on ChemistryViews.
Mayr points out in the work that iBonD
2.0 is organic chemist’s best friends given the fact that it currently covers
more than 32,000 pKa
values of over 20,000 compounds in various solvents and BDE of 5,000 compounds,
which makes it the most comprehensive online edition data pool internationally
and its convenient retrieval functions such as searching by name, formula or
structure meet the needs of users. The BDE parameters involve not only homolysis
and heterolysis energies of compounds but parameters of their corresponding free
radical intermediates. What’s more, it offers related reference search function
to ensure a better experience for users and reliability of data, which is vital
for designing new compounds, developing novel reactions, investigating reaction
mechanisms and building as well as optimizing computational chemistry models.
iBonD 2.0 grows out of iBonD 1.0
launched in March 2016. After elaborating literature searching, sifting and arrangement
of Cheng’s group, it now has become the first most comprehensive and professional
online version of BDE parameters worldwide. It is compatible with multiple
systems and can be used on personal computers and mobile phones. It’s free of
charge and regular renewal and maintenance are secured for pleasant and
reliable user experience. Its URL is http://ibond.nankai.edu.cn or http://ibond.chem.tsinghua.edu.cn and uses and suggestions are warmly welcomed.
The establishment of
such data base undoubtedly brings itself with profound effect on chemistry
research, as Zhou Wenneng, the Deputy Director of Department of Basic Research,
Ministry of Science and Technology puts it, “The completion of iBond embodies
the responsibility of the scientific and technological circles. It fills the
blank of domestic and international work and plays an important role in
promoting the influence of China on international chemistry world.
