Tweezering the Core of a Dendrimer: A Photophysical and Electrochemical Study

Abstract

Dendrimers[1] are complex, yet well-defined, branched compounds that exhibit a high degree of constitutional order, with the possibility of containing selected chemical units at predetermined sites of their structure (core, branches, periph-[*] Prof.

Glassy carbon electrode modified with hemin and new melamine compounds for H2O2 amperometric detection

“…Dendrimers are branched macromolecules with a fractal structure that exhibit a high degree of constitutional order, with the possibility of containing selected chemical units at predetermined sites of their molecules [11]. The dendritic architecture can serve as a versatile platform for host-guest interactions, e.g., in the design of novel encapsulation agents [12], and/or surface interactions with oppositely charged molecules [13].…”

Giant Shape‐Persistent Tetrahedral Porphyrin System: Light‐Induced Charge Separation

“…Pyridinium and bipyrididium chromophores (also known as viologens, namely, 1,1’‐disubstituted‐4,4‐bipyridinium salts) are extensively studied organic fragments due to their photochemical and electrochemical properties. [3] They are widely employed as electron‐acceptor recognition sites and redox switching units in supramolecular systems such as dendrimers,[ 4 , 5 , 6 , 7 , 8 ] rotaxanes,[ 9 , 10 ] and catenanes. [ 11 , 12 ] Moreover, they have been investigated as components for electrochromic displays, molecular batteries, redox mediators, and redox sensors.…”

Electrochemical behavior of a new s-triazine-based dendrimer

“…Compounds such as unsymmetric viologen dendrimers [20], iron-sulfur cluster core dendrimers [21], dendrimers containing meta-terphenyl peripheral groups and a 4,4¢-bipyridinium core [22], ferrocenecored dendrimers [3,23,24], ferrocene-containing carbohydrate dendrimer [25], arylalkyl ether dendrimers based on AB 2 and AB 4 monomer [26], viologenbased dendrimers [27], phenylazomethine dendrimers [28], 4,4¢-bipyridinium core of first, second and third generation dendrimers [1], dinuclear and hexanuclear dendritic ruthenium(II) bipyridine complexes with 2,3-bis(2-pyridyl)pyrazine (2,3-dpp) [29] have been synthesized and characterized.…”

“…Dendrimers are branched compounds with a fractal structure that exhibit a high degree of constitutional order, with the possibility of containing selected chemical units at predetermined sites of their molecules [1]. They are constructed from (AB) n monomers (n usually 2 or 3) in an iterative fashion, using convergent or divergent strategies.…”
