new type of molecular rods consisting of two (or more) rigid units linked by a flexible joint. Consequently we called these constructs articulatedrods (ARs). The syntheses of ARs were carried out by a flexible and modular approach providing access to a number of compounds with various
functionalizations in terminal positions. First applications were presented with pyrene, cinnamoyl and anthracenyl labelled ARs.

One of the basic principles in living nature is based on shape-persistent and
). Herein we wish to report on the synthesis and properties of a new class of semi-flexible molecules which we called articulatedrods (ARs).
Results and Discussion
Synthesis of articulatedrods (ARs)
The synthetic strategy towards ARs has to address the following issues: i) synthesis of legs (short rods
