A Mechanical Planar Chiral Rotaxane Induces Single-Handed Helicity in a Twisted Perylene Diimide. [PDF]
Angew Chem Int Ed EnglA mechanical planar chiral rotaxane (Rmp) is used to induce single‐handed helical chirality (M) in a perylene diimide chromophore, resulting in persistent circular dichroism (CD) and circularly polarised luminescence (CPL). ABSTRACT The twisting of chromophores such as perylene diimides (PDIs) into helical structures affords chiroptical properties from

The Role of Solvent on the Kinetics and Mechanism of the Hydrolysis of Salicylidene Benzoyl Hydrazone [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 1988 The effect of various solvents on the kinetics and mechanism of the hydrolysis of Salicylidene Benzoyl hydrazone (SBH) has been studied at five different temperatures (17-45 C) using U.V. and visible spectrophotometry. In both protic and aprotic solvents,
