The spontaneous and sophisticated side of self-assembly
Previous methods for obtaining such architectures suffer from having very complicated synthetic methods, explains Hirsch. ‘Our aim was to develop a very simple and easy to perform concept for the construction of dendrimers,’ says Hirsch. ‘We were motivated by mimicking supramolecular construction principles that nature uses in biological systems.’
Hirsch says his aim is to provide simple and efficient ways to make functional nano devices. ‘For example, if electro- and photoactive components are brought together in a highly ordered way on a transparent and conductive surface, inexpensive access to new organic solar cells could be possible.’
However, there are several challenges facing future work in this area, Hirsch explains. An absence of any chemical interference between the building blocks ‘is an important requirement for the concept, because only in this way defined architectures can be formed spontaneously,’ says Hirsch.
