- Synthesis, electrochemical and optical absorption properties of new perylene-3,4:9,10-bis(dicarboximide) and perylene-3,4:9,10-bis(benzimidazole) derivatives
-
A series of perylene-3,4:9,10-bis(dicarboximide) (PBI) and perylene-3,4:9,10-bis(benzimidazole) (PTCBI) derivatives that are di-or tetra-substituted at the bay region by electron-donating or electron-withdrawing groups have been synthesized as soluble n-type semiconductors. Optical absorption spectroscopy and electrochemical analysis show that the nature of substitution at the bay region plays a crucial role in the modulation of the electronic properties of these PBI and PTCBI derivatives. Examination of these optical and electrochemical data in the light of energy levels identified by theoretical studies allowed a relationship between the structure and the electronic properties to be established. A relationship between the structure and electronic properties of n-type semiconductors from perylene-3,4:9,10- bis(dicarboximide) (PBI) and perylene-3,4:9,10-bis(benzimidazole) (PTCBI) series substituted at the bay region by electron-donating or electron-withdrawing groups has been established by using the complementary techniques of absorption spectroscopy, electrochemical analysis and theoretical calculations.

- Cooperative spin transition in a lipid layer like system
-
A novel iron(ii) mononuclear spin transition complex [FeL(py)2] displays an abrupt spin transition around 225 K accompanied by a very wide thermal hysteresis loop (~50 K) that spreads out over 100 K. Crystal structure analysis in both low-spin and high-spin states reveals a lipid layer-like arrangement of the complex molecules and provides insights into the spin switching mechanism.
