Self-assembled dendrimers with uniform structure.
Calix[4]arenes substituted at their wide rim by four aryl urea residues (1) form hydrogen-bonded dimers in apolar solvents. Replacement of one urea residue by an acetamido moiety leads to calix[4]arene derivatives (5) which form hydrogen-bonded tetramers under the same conditions. Both self-assembly processes occur independently. Therefore, molecules have been prepared in which a tetra-urea cal...
متن کاملLight-driven molecular switches in azobenzene self-assembled monolayers: effect of molecular structure on reversible photoisomerization and stable cis state.
Both the reversible trans<-->cis photoisomerization and slow thermal back cis-to-trans isomerization of azobenzene-functionalized self-assembled monolayers on gold surfaces have been achieved by rationally designed single-component azobenzene thiol.
متن کاملZnO nanocone arrays on self-assembled Zn2SnO4 base: synthesis, structure, growth mechanism and optical property.
ZnO nanocone arrays on self-assembled Zn2SnO4 base were successfully synthesized via a thermal evaporation method of two-step temperature-rising. The as-prepared ZnO nanocone products had a well crystalline wurzite structure with symmetry about the growth direction along [0001]. Based on the calculation of the lattice misfit between different families of crystal planes of ZnO and Zn2SnO4, Stran...

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
15 صفحه اولSynthesis, structure and molecular modelling of anionic carbosilane dendrimers.
Anionic carbosilane dendrimers of generations 1-3 have been synthesized containing carboxylate G(n)X(C(2)H(4)CO(2)Na)(m) and sulfonate G(n)X(C(2)H(4)SO(3)Na)(m) peripheral groups and derived from two different cores, 1,3,5-(HO)(3)C(6)H(3) (X = O(3)) and Si(C(3)H(5))(4) (X = Si). The peripheral anionic groups make these dendrimers water soluble, despite their highly hydrophobic framework. These ...
