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.

“…[2] 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.…”
