• ; phenylacetylene macrocycles; polydiacetylenes; topochemical polymerization; Introduction The self-assembly of molecular building blocks is an increasingly popular method for the preparation of new semiconducting materials. Rational design of building blocks and their assembly using non-covalent interactions can

Among other things, we have shown that inversion of the amide group configuration (acetanilide vs benzamide) at two different positions on phenylacetylene macrocycles (PAMs) leads to significant changes of the gelation properties and, consequently

To improve the self-assembly properties in the gel state and further yield to better topochemical polymerization yield, the
