Multistate Aggregation‐Induced Chiroptical Properties of Enantiopure Disulfide‐Mediated BisPyrene Macrocycles

Chiroptical Properties of Anilides of (+ )-~-Methylhydrocinnamic Acid

The chiroptical properties of simple amides have been thoroughly investigated. At the same time there are few works concerning the chiroptical properties of anilides':" It was shown that the anilide absorption band at about 240 nm was optically active. For a detailed study of the chiroptical properties of the anili de chromophore and its interaction with an aromatic one we have synthesized a se...

Chiroptical Properties of Amino Acids: A Density Functional Theory Study

Amino acids are involved in many scientific theories elucidating possible origins of life on Earth. One of the challenges when discussing the evolutionary origin of biopolymers such as proteins and oligonucleotides in living organisms is the phenomenon that these polymers implement monomers of exclusively one handedness, a feature called biomolecular homochirality. Many attempts have been made ...

Synthesis and chiroptical properties of layer-block dendrimers

A series of optically active, tartaric acid-based, monodisperse dendrimers 1 4 was prepared. The central core and branching junctures of these dendritic compounds were made up from phloroglucinol units and the surface sectors used were 4-tert-butylphenoxy moieties. The optically active elements, which were derivatives of either (D)or (L)-tartaric acid, served as the chiral linker branches of th...

Chiroptical properties of alternatingly functionalized cellotriose bearing two porphyrin groups

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
