COLOR Ordering Templated by Hierarchized Supramolecular Porous FlatLANDS

Final Report Summary - COLORLANDS (COLOR Ordering Templated by Hierarchized Supramolecular Porous FlatLANDS)

In the field of supramolecular chemistry, covalent, non-covalent and dynamic covalent bonds are essential tools for the construction of functional architectures of increasing structural complexity. As a result, the expansion of this toolbox has attracted a lot of attention from the scientific community. In particular, the area of dynamic covalent chemistry, which combines the characteristics of the covalent (by its robustness) and the non-covalent bond chemistry (by its reversibility) have seen their interest growing over the last decades. Indeed, the wonderful advantages of the dynamic covalent chemistry (i.e. self-repair, self-healing, adaptive self-sorting) can lead to very sophisticated multicomponent architectures. Even though, a lot of progress has been done regarding dynamic covalent libraries, it is quite surprising to see that only a few examples of simultaneous multireaction systems in synthetic functional systems exist in the literature. Hence, our current achievements allowed us to develop a new multidimensional methodology combining the formation of three simultaneous dynamic covalent bonds. This allowed us to simultaneously assemble different chromophores onto a template that governs the spatial color orientation like in natural antenna systems. The development of this orthogonal methodology can prove to be a useful tool for building functional architectures of increasing complexity featuring an unlimited number of potential applications in catalysis, energy conversion, and materials science.

The development of new electronic and optoelectronic materials with superior properties like light weight, durability, flexibility is essential for improving a performance of modern electronic devices. Thus the understanding of structure-property dependence in the molecule and the ability to provide the material with programmed properties is the way forward to program novel materials with breakthrough properties. In the course of this project we developed new synthetic methodologies that allowed us to develop new heteroatom-doped molecular graphenes. By controlling the doping concentration, the doping topology and positions we could gain control on the optoelectronic properties of the resulting materials.
