个人简介

Jianzhang Zhao earned his Bachelor’s degree in chemistry at Hebei University in 1993. He received Ph.D. degree in 2000 at Jilin University. Then he moved to Pohang University of Science and Technology (POSTECH) to do postdoctoral research under supervising of Prof. Kimoon Kim. He worked on supramolecular chemistry of cucurbituril (CB) and he prepared two new cucurbituril derivatives. In 2001, he moved to the Max-Planck Research Unit of Enzymology of Protein Folding at Halle (Saale), Germany. He worked on photochemistry of peptide (photo-switching of the conformation of peptide) with Prof. Gunter Fischer. In 2003, he moved to Department of Chemistry, University of Bath, to do another postdoctoral research. He worked on enantioselective fluorescent chemosensors, with Prof. Tony D. James at Bath. In 2005, Jianzhang Zhao joined Dalian University of Technology as a full professor.

研究领域

Our research focus on molecular photochemistry and photophysics in triplet states' field. Zhao’s group studies the electron transfer (charge separation and charge recombination), energy transfer (via Förster and Dexter mechanisms), intersystem crossing (ISC) and electron spin dynamics of organic compounds and transition metal complexes, with steady state and time-resolved optical and magnetic spectroscopies. Zhao’s laboratory devised series of transition metal complexes containing visible light-harvesting organic chromophores. These complexes show strong absorption of visible light (molar absorption coefficients are up to 100,000 M-1 cm-1) and long-lived triplet excited states (lifetimes are up to 100 microseconds). The principles are to replace the low-lying MLCT states of the conventional transition metal complexes with the ligand-localized LE state, thus the transition probability concerning the photoexcitation and the decay from the triplet state to the ground state were changed. These complexes have been demonstrated to be more efficient in triplet-triplet annihilation upconversion (TTA-UC), photocatalytic hydrogen production, luminescence oxygen sensing and photodynamic therapy. Other applications of these novel transition metal complexes, where intermolecular electron transfer or energy transfer are involved, may be also improved by using these novel photosensitizers.
